GJG100H infrared methane sensor

infrared methane sensor,non-dispersive infrared detection.quick response, long calibration cycle,wide measuring range

Application

With the adoption of an embedded micro-controller and non-dispersive infrared detection technology, this product has overcome the failures that the catalytic sensor’s calibration cycle is short and can be poisoned easily. The sensor has a built-in temperature compensation circuitry of high accuracy so that the measurement accuracy will not drift due to temperature changes. Characterized by accurate measurement, quick response, long calibration period, wide measuring range, low power consumption, long working life, stable performance and high reliability, it can be used together with various types of coal mine safety monitoring systems to continuously monitor the methane concentration in the working environment, and it is immune to other gases.
