The L-com SRAQ-G021 gas sensor module is used to detect the presence and concentration of various refrigerants including R11, R22, R113, R134, R409A, R410A. This device requires a 5 VDC ± 0.2 V power supply, a < 150 mA working current, and has a detection range of 10-1000 ppm. Our 5 VDC ± 0.2 V sensor module is well suited for freon gas detectors, gas leakage, refrigeration units, and air conditioning systems.
The various refrigerants including R11, R22, R113, R134, R409A, R410A etc. sensor module has 4 pin male header which allows for easy integration into gas detection devices. The sensor module features a MQ139 sensing element with good sensitivity and selectivity to various refrigerants including R11, R22, R113, R134, R409A, R410A etc., which makes it less affected by temperature and humidity. This SRAQ-G021 sensor module has a analog and TTL level output modes and it operates at temperatures ranging from -10 to 50 Degrees C.
