氢气气体探测报警器由气体探测器和气体报警控制器两部分组成，气体探测探测器实时检测氢气浓度，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，并上传电脑、发送手机短信等，防止危险事故的发生。

◆ 测量准确：传感器采用进口气体敏感元件，精度高，零点漂移小，抗中毒性能好。

◆ 防爆型设计：可用于工厂条件的1、2区危险场合。

◆ 维修方便：传感器采用数字化模组设计，现场更换时无需校零、标定。

◆ 声光报警：气体检测测器可选配专用的防爆声光报警器，实现现场声光报警。

◆ 浓度显示：气体检测器可选配液晶浓度显示，现场实时显示浓度。
 

Hydrogen Gas Alarm

Hydrogen is a more special gas, flammable & combustible, toxic & harmful, a dual nature gas. The concentration of hydrogen can be detected in real time by hydrogen alarm. It is necessary to install hydrogen gas detect & alarm in the area of hydrogen gas containers or cylinders, to ensure the safety of worker's lift and  business property.
 
Hydrogen gas alarm detects the leakage of hydrogen, utilizing two sensors. The sensor of catalytic combustion type for the flammable & combustible, slower, but cheaper. The sensor of electro-chemical type for toxin, faster, more sensitive, but more expensive. According to the industry situations, detects the flammable & combustible for hydrogen.
 
Hydrogen gas alarm consists of gas detector unit and alarm controller. Gas detector detects the concentration of hydrogen in real time and sends the data to gas alarm controller via cables. The controller displays the concentration, sends audible and visual alarm if the concentration exceeding the scheduled standard, and uploads to computer, sends short messages to mobile, to avoid the dangerous accident.
 
Product feature
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.
