Testo Spare Sensor Head for Refrigerant Leak Detector

This Testo spare sensor head (0554 3180) is essential for keeping your refrigerant leak detector calibrated and ready for service, ensuring accurate detection of even the smallest leaks. In Australia's demanding climate, reliable leak detection prevents costly refrigerant loss and helps maintain system efficiency. You know how frustrating it is to chase a phantom leak or miss a real one because of a tired sensor.

Best for: HVAC technicians, refrigeration mechanics, service teams, and apprentices performing routine leak checks on refrigerant systems.

Compatibility

Designed for Testo leak detectors, this sensor head handles common refrigerants like CFCs, HFCs (partially and fully halogenated), and hydrogen (H2). It's crucial for R32, R410A, and other modern HFC systems. If you're running a different model, check fittings and specs before ordering.

Features

• Compatible with a wide range of refrigerants including CFC, HFC, and H2.
• Detects tiny leaks with an extremely high sensitivity of <3g/year.
• Quick and easy sensor head replacement on compatible Testo leak detectors.
• Compact and lightweight design, ensuring minimal impact on tool handling.

Technical Specifications

What's in the Box

• 1 x Spare head for leak detector (0554 3180) for CFC, HFC (partially and fully halogenated), H2 refrigerants.

Using It on the Job

1. Always power off and disconnect your leak detector before attempting sensor replacement.
2. Carefully remove the old sensor head according to your detector's manual.
3. Install the new 0554 3180 spare head, ensuring it's seated correctly.
4. Power on and allow the detector to warm up and calibrate as per manufacturer instructions before use.
5. Perform a known leak test (e.g., using a test cylinder) to confirm sensitivity after replacement.

Limitations & Safety Notes

• Only use this spare head with compatible Testo leak detector models.
• Refrigerant handling and leak checking should only be performed by ARCtick licensed professionals.
• Always follow the safety guidelines in your leak detector's operating manual.
• This sensor is not designed for ammonia (NH3) leak detection; ensure you have the correct sensor for your application.

Tradie Pro Tip: Keep a spare sensor head in your kit. Nothing worse than a critical leak detection job and a tired sensor; swapping it out on site saves a heap of time and call-backs.
