Wall Mounted LCD Display Gas Detector with 0-2000 ppm CO Sensor
The K500 series wall-mounted gas detector, made with imported high sensitivity sensors and an explosion-proof design, has a long service life. This wall mounted gas detector works as part of an integrated system (with 4-20 mA analog output) or only as an independent system. It has two alarm levels (high level & low level), with different audible and visual alarm signals.
