Spare Head for Ammonia (NH3) Leak Detector

When your Testo 316-4 ammonia leak detector needs a new sensor, this genuine 0554 3181 spare head is the part you need. It's designed to bring back the critical sensitivity required for pinpointing even the smallest NH3 leaks, keeping your plant safe and compliant.

In Australian industrial refrigeration, accurate ammonia leak detection isn't just about efficiency; it's a critical safety measure. Swapping out a worn sensor head is a quick job that saves a lot of headaches on site, especially when you're under pressure to get a system back online without any lingering gas.

Best For

• HVAC/R technicians servicing industrial ammonia (NH3) refrigeration systems.
• Maintenance teams in food processing, cold storage, or chemical plants.
• Anyone requiring precise leak detection for ammonia.

Compatibility

This 0554 3181 sensor head is specifically designed as a direct replacement for Testo 316-4 leakage detectors when set up for ammonia (NH3). It ensures your detector maintains its high sensitivity for ammonia leaks. If you're running a different model, check fittings and specs before ordering.

Features

• Ammonia (NH3) Specific: Precisely calibrated for detecting ammonia gas.
• High Sensitivity: Detects leaks as small as <3g/a, crucial for safety and compliance.
• Easy Replacement: Designed for quick and straightforward sensor head changes in the field.
• OEM Quality: Genuine Testo part ensures reliable performance and accurate readings.

Technical Specifications

What's in the Box

• 1 x Spare head for ammonia (NH3) leak detector (0554 3181)

Using It on the Job

1. Ensure your Testo 316-4 leak detector is powered off before attempting sensor replacement.
2. Carefully remove the old sensor head by unscrewing or unlatching it according to the Testo manual.
3. Install the new 0554 3181 ammonia sensor head, ensuring it clicks or screws into place firmly.
4. Power on the detector and allow it to warm up as per manufacturer instructions.
5. Perform a functional check with a known ammonia source or calibration gas to verify detection and sensitivity.
6. Regularly clean the sensor intake area to prevent dust and debris from affecting performance.

Limitations & Safety Notes

• This sensor head is exclusively for detecting ammonia (NH3) and is not suitable for other refrigerants.
• Always follow safety procedures when working with ammonia systems, including proper ventilation and PPE.
• Refrigerant work, including leak detection on active systems, generally requires a current ARCtick licence in Australia.
• Ensure the main Testo 316-4 unit's firmware is up-to-date for optimal sensor performance.

"After changing any sensor head, give your Testo 316-4 a good few minutes to warm up and stabilise. Always do a quick functional test with a known ammonia source before you start trusting it on a critical leak check."

Pair With

Pair with the Testo 316-4 Leak Detector itself if you're replacing a faulty unit, or grab some calibration gas for regular functional checks to ensure your readings are always spot on.
