氫氣，比較特殊的一種氣體，即具有可燃易爆性，又具有有毒有害性，也就是一種雙重性的氣體，可以通過氫氣氣體報警器對其濃度進行實時檢測。在工廠儲氣罐或氣瓶區(qū)，叉車充電區(qū)，機房等場所，要安裝氫氣濃度探測報警器，以確保員工生命和財產(chǎn)安全。
氫氣濃度探測報警器(Hydrogen Alarm )可選催化燃燒式氣體傳感器測爆，量程為0-99%LEL；也可以選擇電化學式氣體傳感器測毒，量程為0-1000PPM。
測可燃易爆性采用催化燃燒式傳感器，反應慢些，價位便宜；測有毒性，采用專用電化學傳感器，反應快、靈敏度高，價格也高；氫氣根據(jù)行業(yè)情況，測可燃易爆性即可。
氫氣氣體探測報警器由氣體探測器和氣體報警控制器兩部分組成，氣體探測探測器實時檢測氫氣濃度，氣體報警控制器接收氣體探測器檢測的濃度，并顯示，濃度一旦超標可聲光報警提醒，并上傳電腦、發(fā)送手機短信等，防止危險事故的發(fā)生。
氫氣氣體濃度探測報警器產(chǎn)品特點：
◆ 測量準確：傳感器采用進口氣體敏感元件，精度高，零點漂移小，抗中毒性能好。
◆ 防爆型設計：可用于工廠條件的1、2區(qū)危險場合。
◆ 維修方便：傳感器采用數(shù)字化模組設計，現(xiàn)場更換時無需校零、標定。
◆ 聲光報警：氣體檢測測器可選配專用的防爆聲光報警器，實現(xiàn)現(xiàn)場聲光報警。
◆ 濃度顯示：氣體檢測器可選配液晶濃度顯示，現(xiàn)場實時顯示濃度。

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.
