One,               Product use and scope

use:

A) 多参数气体测定器(以下简称测定器)可同时连续检测 CH 4 O 2 CO CO 2 4 种气体的浓度, CD4 ( A) Multi-parameter gas measuring device (hereinafter referred to as measuring device) can continuously detect the concentration of four kinds of gases: CH 4 , O 2 , CO , and CO 2 .

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, The alarm can be exceeded. The tester uses an 8 -bit microcontroller as the control unit. It uses high-precision detection elements with high sensitivity and fast response speed.

128*64 液晶,显示清晰可靠。 The screen adopts 128 * 64 LCD with wide temperature range , and the display is clear and reliable. When the concentration of the test gas in the environment reaches or exceeds or falls below

When the alarm value is preset, the detector will give an audible and visual alarm immediately.

Applies to:   Underground emergency shelter environment.

two,               Features

CO 2 含量的多参数气体测定器 Multi-parameter gas detector capable of measuring CO 2 content

Equipped with silicone sleeve, good drop performance

three,               Technical principle


内部进行运算处理和补偿,最终显示在240 × 64点阵液晶上。 The working principle of the tester is as follows: the measured gas and temperature and humidity in the environment pass through the tester array and are converted into digital signals, which are sent to the MCU for arithmetic processing and compensation, and finally displayed on the 240 × 64 dot matrix LCD. 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。 According to the measurement result of the tester, the tester makes corresponding actions, and at the same time controls the status indication, voice prompt, battery voltage, alarm output and keyboard input and makes corresponding processing.

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。 It adopts a dedicated charging chip, cooperates with the CPU to monitor the whole process, and uses an uninterruptible power supply switching method to achieve continuous operation after the system is powered off.
