Description
The SNDWAY SW-743A is a precision-engineered digital halogen gas detector designed for the rigorous demands of HVAC/R maintenance and industrial leak detection. This handheld unit utilizes advanced semiconductor sensing technology to identify halogenated refrigerants including CFCs, HCFCs, and HFCs with high sensitivity. The device features a flexible gooseneck probe allowing for deep penetration into complex machinery and ductwork to pinpoint leaks in evaporator coils and compressor fittings. The integrated digital processing unit offers a measurement range up to 1000 PPM, providing real-time feedback via audible and visual alarms. Original Engineering ensures high stability and interference resistance against background environmental factors, ensuring accurate diagnostics in variable industrial conditions.
