Detector de scurgeri de agent frigorific Extech RD350

HVAC technicians and refrigeration service professionals rely on the Extech RD350 to pinpoint refrigerant leaks in air conditioning and cooling systems. This handheld detector uses a heated diode sensor to identify CFCs, HCFCs, HFCs, and HFOs, including R-134a, R-410a, and R-1234yf, with a sensitivity of 0.1 oz/year for R-134a. The flexible 16-inch probe reaches into tight spaces, while the multi-color LED bar graph and variable frequency alarm provide clear visual and audible leak indication.
