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(bào)警器對(duì)其濃度進(jìn)行實(shí)時(shí)檢測(cè)。在工廠儲(chǔ)氣罐或氣瓶區(qū)，叉車充電區(qū)，機(jī)房等場(chǎng)所，要安裝氫氣濃度探測(cè)報(bào)警器，以確保員工生命和財(cái)產(chǎn)安全。
氫氣濃度探測(cè)報(bào)警器(Hydrogen Alarm )可選催化燃燒式氣體傳感器測(cè)爆，量程為0-99%LEL；也可以選擇電化學(xué)式氣體傳感器測(cè)毒，量程為0-1000PPM。
測(cè)可燃易爆性采用催化燃燒式傳感器，反應(yīng)慢些，價(jià)位便宜；測(cè)有毒性，采用專用電化學(xué)傳感器，反應(yīng)快、靈敏度高，價(jià)格也高；氫氣根據(jù)行業(yè)情況，測(cè)可燃易爆性即可。
氫氣氣體探測(cè)報(bào)警器由氣體探測(cè)器和氣體報(bào)警控制器兩部分組成，氣體探測(cè)探測(cè)器實(shí)時(shí)檢測(cè)氫氣濃度，氣體報(bào)警控制器接收氣體探測(cè)器檢測(cè)的濃度，并顯示，濃度一旦超標(biāo)可聲光報(bào)警提醒，并上傳電腦、發(fā)送手機(jī)短信等，防止危險(xiǎn)事故的發(fā)生。
氫氣氣體濃度探測(cè)報(bào)警器產(chǎn)品特點(diǎn)：
◆ 測(cè)量準(zhǔn)確：傳感器采用進(jìn)口氣體敏感元件，精度高，零點(diǎn)漂移小，抗中毒性能好。
◆ 防爆型設(shè)計(jì)：可用于工廠條件的1、2區(qū)危險(xiǎn)場(chǎng)合。
◆ 維修方便：傳感器采用數(shù)字化模組設(shè)計(jì)，現(xiàn)場(chǎng)更換時(shí)無需校零、標(biāo)定。
◆ 聲光報(bào)警：氣體檢測(cè)測(cè)器可選配專用的防爆聲光報(bào)警器，實(shí)現(xiàn)現(xiàn)場(chǎng)聲光報(bào)警。
◆ 濃度顯示：氣體檢測(cè)器可選配液晶濃度顯示，現(xiàn)場(chǎng)實(shí)時(shí)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.
