TBS toxic gas detector

● Sewage and sewage treatment

Pump room, water collecting well, grille well, chlorination room, etc.


TBS toxic and combustible gas detector uses high-performance electrochemical sensors. Sensor elements of different gases can be used to detect a variety of different toxic and harmful gases. At the same time, the measured harmful gas concentration value can be converted into a 4-20 mA standard signal output. TBS The single-point wall-mounted gas alarm is mainly used for gas detection and alarm in non-explosion-proof occasions on industrial sites. It is equipped with one AC220V and one passive switching control signal output, which can control exhaust fans and other equipment.
