由气体探测器(Gas Detector)和气体报警控制器(Gas Controller)两部分组成。气体探测器，又称气体检测器，实时检测乙醇(酒精）浓度，气体报警控制器接收气体探测器检测的浓度，并显示，浓度一旦超标可声光报警提醒，并可联动喷淋、排风等外接设备，或者上传电脑、发送手机短信等，防止危险事故的发生。

Alcohol Gas Alarm
Summary
Alcohol gas 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 mobiles, avoiding the dangerous accidents.
Feature of Alcohol Gas Alarm
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.
