🌡️ Digital eyes that read temperature and humidity to the nearest tenth of a degree.
The T/H probe is the combined sensor that detects temperature and relative humidity inside the incubator. It sends the data to the EVO Plus or MiniLed Advanced control unit, which adjusts heating and humidification accordingly.

Available in the sensor-only version or complete with sensor + protection + cable

Quick diagnosis: display showing "ERR" or asterisks (**), incorrect readings, temperature or humidity not matching the control thermometer, frozen values.

Solution: Original FIEM Temperature/Humidity probe for EVO Plus and MiniLed Advanced control units.

Slight decimal fluctuations are within the normal characteristics of this type of sensor.

⚠️ When to replace it: If the probe isn't working, the control unit can't properly regulate temperature and humidity. The incubator will operate "blind," and you risk losing the entire brood.

⚙️ How the EVO Plus / MiniLed T/H Probe works

The T/H probe is a combined digital sensor that simultaneously measures temperature and relative humidity inside the incubation chamber. It is the component that "sees" environmental conditions and communicates them to the electronic control unit.

It uses a professional precision sensor with self-calibration, capable of detecting minimal variations: accuracy of ±0.1°C for temperature and ±1.5% for relative humidity. This data is processed by the EVO Plus or MiniLed Advanced control unit, which decides when to activate the heating element to heat or the humidifier to increase humidity.

Without a functioning probe, the control unit has no way of knowing what's happening inside the incubator. It's like driving a car with the dashboard off: you don't know how fast you're going or how much gas you have.

📋 Exploded technical reference: this component corresponds to the number 19 in the exploded diagrams of FIEM COSMO incubators. Useful for identification during maintenance.


🔍 When to replace this part

Replace the T/H probe if you notice:

  • Message "ERR" or asterisks (**): the display shows error instead of temperature or humidity values.
  • Wrong readings: the indicated temperature does not correspond to the control thermometer (deviation greater than 1°C).
  • Humidity always at zero or 99%: fixed values that do not change despite real variations.
  • Values that jump: unstable readings that change abruptly for no reason.
  • Resistance always on or always off: the control unit does not receive correct data and does not regulate.

⚠️ Why it happens and what you risk

The T/H probe deteriorates primarily from prolonged exposure to the high humidity typical of incubation. Over time, condensation can infiltrate the sensor, causing oxidation of the contacts or damage to internal components. Repeated temperature changes can also accelerate wear.

A faulty probe is a serious problem: the control unit can't regulate properly, and the incubator operates uncontrollably. The temperature could rise too high (killing the embryos) or fall too low (stopping development). Improper humidity levels cause embryos to fail to break their shells. The control unit is often thought to be the problem, but in 70% of cases, the probe is the culprit.


✅ Compatibility verified

This probe is specific for FIEM incubators with advanced digital control units:

📦 Advanced Mini LED Control Unit
Version with 2.4 inch color LCD control unit and preset programs for species


📦 Central EvoPlus
Version with 3-digit digital display and temperature/humidity control

⚠️ Important note: This probe is NOT compatible with the old Miniled versions with Red Display or the Analog version (which do not have a digital humidity sensor).

🔧 Assembly in 4 simple steps

⏱ Estimated time: 10-15 minutes | 🔧 Tools: Phillips screwdriver (for possible fixing)

  1. Turn off and unplug the incubator
    Unplug the machine from the electrical outlet. Let it cool if it was running.
  2. Photograph the current connection
    Before disconnecting the old sensor, take a picture of the connector on the control unit. This will help you reconnect the new one correctly.
  3. Replace the probe
    Disconnect the old probe's connector from the control unit (gently pull it out). Remove the probe from its housing. Place the new probe in the same spot and connect the connector.
  4. Final test
    Plug the incubator back in and turn it on. Verify that the display shows the correct temperature and humidity (not "ERR"). Compare it to the control thermometer to verify accuracy.
💡 Tip: After replacing the sensors, let the incubator stabilize for 30-60 minutes before checking the accuracy of the readings. New sensors require a short "break-in" period.

🛡️ How to make it last longer

  • Positioning: make sure the probe is not in direct contact with water or condensation drops.
  • Cleaning: Gently wipe the probe with a dry cloth between cycles.
  • Calibration: Periodically check that the readings match the control thermometer. If you notice any discrepancies, use the control unit's calibration function.
  • ⚠️ DO NOT do: Do not immerse the probe in water, do not use aggressive detergents, do not pull the cable.

Anti-Vibration Metal Supports for CIP 28 and 40...

€1.28
Availability: 1000 In Stock
CIP 28 and 40 Metal Fan Motor Brackets – Small but essential. These brackets keep the fan perfectly aligned, ensuring uniform air circulation in the incubation chamber. Without them, abnormal vibrations and noises can compromise thermal stability and therefore hatching success.

A customer from Vicenza called me worried: he could hear a metallic rattling noise from his CIP CIP 40 incubator on the 12th day of incubating pheasant eggs. After checking, we discovered that one of the fan's metal supports had come loose. Once fixed, the machine went silent again, and the hatching was successful.

When are they needed? If you hear abnormal vibrations, metallic noises, or rattling coming from the fan compartment, or if you notice that the fan isn't perfectly centered, the bearings probably need replacing. Even during preventative maintenance , when you replace the fan motor, it's good practice to check the condition of the bearings.

⚠️ Before ordering: Unplug the fan, open the control panel, and visually inspect the brackets for damage, rust, or missing parts. Sometimes, a thorough cleaning of the fan is enough to eliminate the noise.

📸 Not sure? Send us a photo on WhatsApp (incubator open, fan visible): we'll help you determine if the supports are the problem or if there's something else.

📦 Logistics: Ships in 1 business day, delivery 2-4 days. Warranty: 24 months for private customers / 12 months for VAT number. Since 1975, FIEM has been synonymous with reliability in the poultry sector.

Fiem CIP 40 Metal Support for Humidity Channel

€6.71
Availability: 1000 In Stock
CIP 40 Humidity Channel Metal Support – The bracket that holds the water channel in place. This metal support ensures stability and proper positioning of the humidity tray on the bottom of the incubator.

A customer in Rovigo was having strange problems: the drain was constantly shifting, water was pouring out of one side, and the humidity was unstable. Upon inspection, the metal support had warped and was no longer holding the tray in place. The support was replaced, and the problem was solved in 5 minutes.

When is it needed? If the channel moves, wobbles, or doesn't stay in place , the metal support is probably warped, bent, or missing. Even when replacing the channel itself, always check the condition of the support.

💰 Price: €5.50 (excluding VAT, shipping) – FIEM WAREHOUSE COMO

⚠️ ATTENTION: This support is specific for CIP CIP 40. The CIP CIP 28 model has a different support (SUPP.BAC.CIP28).

Minimum order €20: Add the channel (€6.50), thermometer (€22.05) or other spare parts.

Fiem Smart Fan Protection Net (Exploded View 10)

€11.50
Availability: 1000 In Stock

🛡️ The fan guard isn't just a safety net: it's what prevents accidental contact with the moving blades and protects the fan itself from feathers and debris!

At €9.45 (excluding VAT) , the PROT.SMART is the protective metal mesh that covers the fan of your Smart incubator. It's not an optional accessory: it prevents objects, feathers, or worse, curious fingers from coming into contact with the rotating blades, and at the same time prevents debris from obstructing the fan and compromising ventilation.

🔧 This protective grille maintains optimal airflow while filtering out large particles that could damage the engine. The mesh is sized for maximum protection without impeding vital air circulation for embryos.

⚠️ When should you replace it? If the mesh is broken or bent, leaving dangerous gaps, if the mesh is warped and no longer fits properly, if it's rusted or corroded, or if it's missing after maintenance.

💡 Using the incubator without the protective grille is dangerous and can cause damage to the fan if objects enter the blades.

Compatible with the Smart model as indicated in the FIEM price list.

📱 Is your grill damaged? Send us a photo on WhatsApp to check compatibility.

Fiem Anti-Condensation Humidity Probe...

€3.54
Availability: 999 In Stock

💧 The humidity sensor cover is essential protection that keeps the humidity sensor safe from the harsh incubator environment! (dust, washing, etc.)

The CUST.S.UMID protects the delicate humidity probe from the extreme conditions inside the incubator: constant high humidity, heat, and possible splashes of water when filling the trays. Without this protective case, the probe rapidly deteriorates, compromising the vital 47-62% humidity readings required for the various phases.

🛡️ This case allows the sensor to properly detect humidity while protecting it from physical damage and excessive condensation. It is designed with calibrated openings that allow humid air to pass through for measurement, but prevent direct water from entering.

⚠️ When should you replace it? If it has cracks or breaks, if it no longer protects the probe adequately, if it is deformed by heat, if the openings are blocked by deposits, or if it is missing after humidity probe maintenance.

💡 A damaged case exposes your expensive humidity probe to premature failure. It's better to invest in a new case than to have to replace the entire probe!

Compatible with FIEM humidity probes .

Fiem Smart Automatic Egg Turning Grid (Exploded...

€12.10
Availability: 1000 In Stock

🥚 The 32/A egg turning grid is not a simple divider: it is the system that gently rolls the eggs, replicating the natural movement of the hen!

At €9.98 (excluding VAT) , this grid (part no. 8 in the exploded view) neatly divides the rows of eggs and, connected to the tensioning system, rolls them with precision. Just like a mother hen turns each egg with her beak several times a day, this grid, moving back and forth for 30 minutes, gently rolls each egg, preventing the embryo from sticking to the shell.

🔄 Movement is vital: without regular rotation, the embryo adheres to the internal membrane and dies. As specified in the FIEM manual, the gearmotor moves the grid in hourly cycles (30 minutes forward, 30 minutes backward), causing the eggs to roll on their axis. It's this constant action that increases hatching rates from 20% without voltage to 80-90% with the correct voltage!

⚠️ When should you replace it? If the dividers are bent and the eggs don't roll evenly, if it no longer engages the gearmotor pin, if it has breaks that block some eggs, or if wear and tear after many cycles compromises the smooth movement.

💡 The dividers are not random: they keep the eggs at the right distance to roll without bumping into each other, organize the space for maximum capacity, and ensure that each egg receives the necessary movement.

Compatible with Smart only , designed for Smart automatic or manual voltage system.

📱 Eggs not rolling properly? Send a WhatsApp video of the movement for immediate diagnosis.

🚚 Shipping from Como in 1 day. Minimum order €20. FIEM since 1975 , natural movement for excellent results. 24-month warranty for private individuals, 12 VAT numbers.

Fiem Smart Transparent Lid (Exploded View 14)

€37.20
Availability: 999 In Stock

🔝 The clear lid isn't just a window onto your eggs: it's the thermal barrier that keeps temperature and humidity stable, determining the success of your hatchings!

At €30.50 (excluding VAT) , the Smart Lid (part #14 in the exploded view) is much more than just a clear plastic cover. It's designed to create the perfect climate chamber that maintains a constant 37.7°C and the necessary humidity, while allowing you to observe development without constantly opening the lid.

🌡️ The transparency of the material is no accident: it allows you to visually check the thermometer and eggs without losing heat. Any unnecessary opening can cause fluctuations of 2-3°C, which slows embryonic development, which is why an intact and well-sealed lid is essential.

⚠️ When should you replace it? If it has cracks or breaks, even small ones, that cause heat and moisture leaks. If the plastic is cloudy from years of use and you can't see clearly inside. If it no longer seals tightly, leaving gaps. If it has been deformed by excessive heat or impacts.

🔧 As the manual indicates, during the last two days of hatching, the lid must be kept tightly closed to maintain humidity at 62%. It's tempting to open the lid to watch the chicks hatch, but each opening compromises subsequent hatchings!

Compatible exclusively with the Smart model . The specific design with the correct curvature ensures optimal air circulation studied by FIEM.

📱 Not sure about the condition of your lid? Send us photos of the complete incubator and lid from various angles on WhatsApp .

🚚 Protected shipping from Como in 1 business day. Reinforced packaging to prevent breakage. FIEM since 1975 , Padovan Avicoltura guarantees original spare parts. 24-month warranty for private individuals, 12 VAT numbers.
