氧气浓度报警器

The instrument is widely used in the coal mine is flammable combustible gas mixture in the working environment for the continuous monitoring of the concentration of oxygen gas, and sound and light alarm when reach the set concentration. Electrochemical sensor by diffusion of oxygen gas reaction directly with the environment to produce the current signal of linear change, by sampling, filtering amplifier, modulus conversion, software process in the LED screen display of oxygen gas density.

Oxygen concentration alarm
氧气浓度报警器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。氧含量报警器具有声光报警、零点跟踪，整机功耗低、精度高、寿命长、外形美观、便于携带。
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境中的氧气气体反可打零贰玖捌捌柒贰陆柒柒叁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。（cl）本文ation alarm is a kind of imported electrochemical sensor and single-chip microprocessor system is a new type of all-digital gas detection instruments, can calibration calibration without open the casing. Oxygen content alarm with sound and light alarm, zero tracking, low power consumption, high precision, long life, good appearance, please dozen zero two nine pure two lu and pure pure three easy to carry.
