1:for lpg, co, h2s gas etc 2:catalytic,electrochemical, pid sensor 3:Explosive-proof 4:ISO9001&CE 5:4~20mA output

It's a lpg gas detector, Gas Analyzer, Alarm with HBUS  signal transmission.It can network with our gas monitor JB-TB-AT2020SH,JB-TB-AT2020DH and JB-TB-AT2020FH.

Feature:

1.Adopts imported sensor with high measurement accuracy, high stability, strong anti-poisoning and anti-interference ability.

2.Automatic recognition and protection the concentration of sensors , short-circuit and open-circuit of sensors, and automatic fault detection .

3. Explosion -proof design, it is suitable for II gas environment.

4. Adopts HBUS four buses communication mode ,power wire and signal wire both use non-polarity  design.

5: With automatic protection function to avoid damage to hardware caused by short -circuits in the course of construction and in the use.

6:Built-in one passive switching output contacts,and easily to network with Sound and Light Alarm or spot site control.

7:Pipe-mounted,ceiling-mounted and wall-mounted optional.
