一、 產(chǎn)品用途和適用范圍
用途:
CD4多參數(shù)氣體測(cè)定器(以下簡(jiǎn)稱測(cè)定器)可同時(shí)連續(xù)檢測(cè)CH4、O2、CO、H2 S共4種氣體的濃度,并可超限報(bào)警,測(cè)定器采用8位微控制器作為控制單元,
采用高精度檢測(cè)元件,靈敏度高、響應(yīng)速度快,屏幕采用寬溫范圍的128*64液晶,顯示清晰可靠。當(dāng)環(huán)境中檢測(cè)到待測(cè)氣體的濃度達(dá)到或超過(guò)或低于預(yù)置報(bào)警值時(shí),
測(cè)定器立即發(fā)出聲光報(bào)警。
適用于:

1:液晶2:載體催化元件 3:功能鍵4:硫化氫傳感器5:一氧化碳傳感器 6:LED報(bào)警透明窗 7:氧氣傳感器 8:開(kāi)機(jī)鍵 9:充電口
二、 產(chǎn)品特點(diǎn)
配備硅膠套,跌落性能好
三、 技術(shù)原理
測(cè)定器工作原理如下:環(huán)境中的被測(cè)氣體及溫濕度經(jīng)過(guò)測(cè)定器陣列,轉(zhuǎn)化為數(shù)字信號(hào),該信號(hào)送至MCU內(nèi)部進(jìn)行運(yùn)算處理和補(bǔ)償,最終顯示在240×64點(diǎn)陣液晶上。根據(jù)測(cè)定器的測(cè)量結(jié)果,測(cè)定器作出相應(yīng)的動(dòng)作,同時(shí)控制狀態(tài)指示、語(yǔ)音提示、電池電壓、報(bào)警輸出以及鍵盤輸入并做出相應(yīng)的處理。
采用專用的充電芯片,配合CPU全程監(jiān)控,并采用不間斷電源切換方式,實(shí)現(xiàn)系統(tǒng)的斷電后連續(xù)運(yùn)行。

Applications:
CD4 portable Multi-gas detector is an intrinsically safe and explosion-proof instrument and is designed to deter the gases.
It can simultaneously monitors up to four atmospheric hazards including carbon monoxide (CO), oxygen (O2),
combustible gas (%LEL), and hydrogen sulphide(H2S). Compact and lightweight, CD4 portable Multi-gas detector activates audible, visual and vibrating alarms in the event of a low or high alarm condition.
CD4 portable Multi-gas detector is unparalleled in its versatility, capability and overall value. Water-resistant line of portable gas detectors has transformed the market with its matchless array of features.
It is used at the underground coal mine and mine safety inspection mainly.
Certainly, it is also applied to fire fighting, confined space, chemical industry,
oil and all kinds of environment that needed to measure the hazardous and toxic gases
