· 产品介绍
一、 产品用途和适用范围
用途:
CD4多参数气体测定器(以下简称测定器)可同时连续检测CH4、O2、CO、H2 S共4种气体的浓度,并可超限报警,测定器采用8位微控制器作为控制单元,
采用高精度检测元件,灵敏度高、响应速度快,屏幕采用宽温范围的128*64液晶,显示清晰可靠。当环境中检测到待测气体的浓度达到或超过或低于预置报警值时,
测定器立即发出声光报警。
适用于:

二、 产品特点
配备硅胶套,跌落性能好
三、 技术原理
测定器工作原理如下:环境中的被测气体及温湿度经过测定器阵列,转化为数字信号,该信号送至MCU内部进行运算处理和补偿,最终显示在240×64点阵液晶上。根据测定器的测量结果,测定器作出相应的动作,同时控制状态指示、语音提示、电池电压、报警输出以及键盘输入并做出相应的处理。
采用专用的充电芯片,配合CPU全程监控,并采用不间断电源切换方式,实现系统的断电后连续运行。

CD4 portable Multi-gas detector is an 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
