Portable Infrared Refrigerant Gas Leak Detector-AM4209AM4209

Cubic portable gas detector AM4209 leverages over 20 years' mature NDIR (non-dispersive infrared) technology platform to provide multiple refrigerant gas leakage detection solutions. It could customized to detect HFCs, HFOs and blends refrigerant gases including R32/R290/R410A/R134a/R454A/R454B/R454C/R1234ze/R1234yf, with the superior features of fast response, ppm-level detection limit, strong anti-interference ability and longer lifespan.

AM4209 has the design of TFT LCD screen which provides clear and quantitative real-time refrigerant leakage indication. Besides AM4209 has multiple indicators (loud beeper alarm & red LED flashes) at the tip to enable detection much easier to track down even minor leakage in various environments. And the AM4209 can be easily recharged and holds a charge for up to 10 hours, benifit from large-capacity batteries and the type-C charging interface.

In the HVAC and industrial inspection fields, AM4209 provides the most credible and reliable sensing and detection solutions for our customers.
