高精度氧气测试器
High precision oxygen tester
氧气测定器-CYH25是一种采用进口电化学传感器和单片机微处理器系统的新型全数字式气体检测仪器，无需打开机壳便可进行校准标定。氧气测定器-CYH25具有声光报警、零点跟踪，整机功耗低、精度高、寿命长、外形美观、便于携带。
氧气测定器-CYH25广泛适用于煤矿井下存在易燃易爆可燃性气体混合物的工作环境中连续监测氧气气体的浓度，并在达到设定浓度时进行声光报警。电化学传感器以扩散方式直接与环请打零贰玖捌捌柒贰陆柒柒叁境中的氧气气体反应产生线性变化的电流信号，经采样，滤波放大，模数转化，软件处理后在LED屏上显示氧气的气体浓度值。Oxygen meter - CYH25 is a kind of imported electrochemical sensor and single-chip microprocessor system a new type of full digital gas detection instruments, no
Open the casing can be calibrated calibration. With sound and light alarm is oxygen meter - CYH25, zero tracking, low power consumption, high precision and life
Long, good appearance, easy to carry.
Oxygen meter - CYH25 is widely used in the coal mine is flammable combustible gas mixture in the continuous monitoring of oxygen gas in the working environment
Concentration, and concentration when setting for sound and light alarm is reached. Electrochemical sensor directly with ring please dozen zero spread way two nine pure two lu and pure and pure
3 in oxygen gas in the linear change of current signal generated in the reaction, the sampling, filtering amplifier, modulus conversion, software in LED screen after processing
According to the oxygen gas density.
本仪器广泛适用于煤矿井下存在易燃易爆可燃性气体混合物的工作环境中连续监测氧气的浓度，并在超限时进行声光报警。当仪器用于测量空气中的氧气时，电化学传感器以扩散方式直接与环境中的气体反应，产生线性变化的电压信号。信号经线性放大器放大后输入单片机内的A/D转零贰玖陆捌伍捌壹柒零一换器转换为数字信号，经过微处理器数据处理，由数码管显示出氧气浓度，当氧气浓度低于设定的报警点后，仪器发出声光报警信号。仪器具有电池欠压报警和自动关机功能。
