Mashgas alarm composed of gas detector and controller.The detector monitors in real time the concentration of methane. The controller receives the detection results from detector, and displays the concentration. The controller sends the audible & visual alarm once the concentration over the scheduled value, and starts the linkage devices (sprayer, fan, etc.), or uploads to PC, sends short messages to s, avoiding the dangerous accidents.

1. Accurate measurement: sensor with imported gas sensory unit, high precision, less zero shift, strong anti-poisoning.

2. Explosion-proof design: suitable for 1-area and 2-area dangerous site in firm.

3. Maintenance-free: sensor designed with digital module group, no need to zero setting and calibration.

4. Audible and visual alarm: gas detector if equipped with explosion-proof audible and visual alarm, sending audible & visual alarm on the spot.

5. Concentration display: gas detector if equipped with LCD, displaying the concentration on the spot.
