Integrity first, quality first and affordable price!
This product uses internationally advanced non-dispersive infrared detection technology to overcome the shortcomings of thermal catalytic principle sensors such as short calibration cycles and easy poisoning. It also uses embedded microcontroller technology to build in an accurate temperature compensation circuit so that the detection accuracy will not change due to temperature. And drift.
The instrument has the characteristics of accurate measurement, fast response speed, long calibration cycle, not affected by other gases, wide measurement range, low power consumption, long service life, stable performance and high reliability.
The instrument can easily set the working point through the remote control and at the same time output ~ Hertz frequency signals and digital signals to facilitate use with various types of coal mine safety monitoring systems.
It is mainly suitable for continuous measurement of gas concentration in coal mine underground mining working faces, return air tunnels, electromechanical tunnels and other environments with gas explosions. The instrument has functions such as measuring and displaying instantaneous gas concentration, over-limit alarm and output power-off control signal, infrared remote control adjustment, and digital communication.
