Larson Electronics released an explosion-proof hydrocarbon gas sensor with a Class I, Division 1 and 2 (Groups B, C, D) rating for combustible environments. The device is used to test and monitor levels of toxic gas in the air. The EXP-SNR-TG-EC-ITS-ALG-HC200 is configured to uncover hydrocarbon vapors with a detection range of 0-200 ppm. Equipped with a sensor, amplifier and memory module, the compact unit offers non-digital, analog output (4-20 mA output range). An integral sensor holder keeps the device stable during use. For seamless monitoring, the explosion proof hydrocarbon sensor features an LCD graphic display. In three-wire mode, a backlight is available for viewing in low-light environments. The sensor is cast aluminum and designed for flammable environments with a temperature range of -25º C to +55º C.
