The Klein Tools ET160 Refrigerant Gas Leak Detector identifies leaks of CFCs, HFCs, HCFCs, and refrigerant blends using an 18-inch flexible gooseneck for access in tight spaces. Audible and visual LED alarms intensify proportionally as gas concentration increases, enabling technicians to pinpoint leak sources quickly. Housed in durable polycarbonate, it runs on 4 AAA batteries and includes a storage pouch. Designed for HVAC and refrigeration technicians servicing commercial and residential refrigeration systems. Backed by a 1-year limited warranty.
What refrigerants does the ET160 detect?
CFCs, HFCs, HCFCs, and their blends — covering R-22, R-410A, R-134a, R-404A, R-407C, and most common HVAC and refrigeration refrigerants. It uses a heated diode sensor tuned for halogenated refrigerant gases.
Can the ET160 detect CO or combustible gases?
No — the ET160 is designed exclusively for halogenated refrigerant detection. For carbon monoxide use the ET110; for combustible gas leaks (methane, propane) use the ET120 or ET190.
How does the alarm intensify as I approach a leak?
The ET160 produces audible and visual (LED) alerts that increase in frequency and LED count as refrigerant concentration rises near the probe tip. Moving slowly toward fittings, valves, and coil connections allows you to home in on the source by following the rising alarm rate.
Where should I probe when checking HVAC systems?
Key locations: service valve stems, flare or braze fittings at evaporator and condenser coil connections, schrader valve cores, and line set connections at equipment cabinets. Refrigerants are heavier than air — probe below fittings and joints where escaping gas pools.
Does the ET160 require calibration or sensor replacement?
Heated diode sensors have a finite service life and may drift over time. If the detector fails to alarm on a known refrigerant source, sensitivity has degraded and service or sensor replacement is indicated. No field calibration procedure is provided — contact Klein Tools support for service.
