Gas leakage measurement in a range of 0-1000 ppm. 3 built-in digital alarm output and 1 analog 4-20 mA output. The sensor can be set up using a PC with the HB Configuration Tool.The sensor element has a lifetime of 2 years and can easily be replaced. On the front, you can find 4 integrated LEDs for displayof the supply (green) as well as 3 alarm levels (red, orange, and yellow). The sensor is factory calibrated and verification during the lifetime can be done with high gas concentrations. The sensor is optimized for use in areas where cleaning solvent are used.Built-in heating element ensures low ambient temperatures down to -30 ° C.
