Description
Fieldpiece SRL8 Heated Diode Refrigerant Leak Detector — Professional Grade
The Fieldpiece SRL8 is a professional heated diode refrigerant leak detector built for HVAC technicians who need fast, reliable leak detection across all common refrigerants. With a flexible 16-inch gooseneck probe and audible/visual alarm, the SRL8 helps you find leaks quickly — even in tight spaces behind coils and in equipment rooms.

Why Technicians Trust the SRL8
- Heated diode technology — the gold standard for HFC/HCFC refrigerant detection
- Detects A2L refrigerants including R-32 and R-454B (the R-410A replacement)
- Replaceable sensor tip — extends tool life and reduces long-term cost
- USB-C rechargeable — no AA batteries to replace in the field
- Flexible gooseneck probe — reaches behind coils and into tight spaces
Frequently Asked Questions
Yes. The SRL8's heated diode sensor detects all HFC and A2L refrigerants including R-454B (Opteon XL41). As the industry transitions away from R-410A, the SRL8 is ready for the new refrigerant era.
The SRL8 sensor tip lasts up to 5 years under normal use. Replace it when sensitivity decreases or when the detector fails its self-test. Replacement tips are available separately.
Heated diode detectors are more sensitive to HFCs and HCFCs (like R-410A and R-22) but require periodic sensor replacement. Infrared detectors are longer-lasting but less sensitive at very low leak rates. For most residential and light commercial work, heated diode (like the SRL8) is the preferred choice.
