1. Description


    TX721-A1B is a type of gas sensor developed based on non-dispersive infrared spectroscopy (NDIR) technology. It can detect gases such as methane and propane hydrocarbons. It adopts a diffuse air intake method and is suitable for gas detection and early warning in the industrial field. At the same time, it meets the requirements of intrinsically safe explosion-proof certification. The internal temperature/humidity compensation algorithm is added to adapt to different temperature environments. It has the characteristics of high sensitivity, anti-poisoning, long life, and use in hypoxic environments.


    The TX721-A1B gas sensor is equipped with an ultra-low power light source and detector. At the same time, the single light source and dual detector differential measurement principle is used to correct the test channel through the reference channel, which can effectively solve the influence of light source attenuation and environmental factors. The optical path part adopts coating processing technology to minimize the loss of infrared light during the reflection process and the problem of optical path oxidation. At the same time, the body is made of SUS304 material, which is non-toxic and not easy to get dusty or oily, and has a strong texture and is safe and healthy.
