AS8903(2合1）气体检测仪Gas detector
产品特点
气体检测仪是一种气体泄露浓度检测的仪器仪表工具，主要是指便携式/手持式气体检测仪。主要利用气体传感器来检测环境中存在的气体种类，气体传感器是用来检测气体的成份和含量的传感器。一般认为，气体传感器的定义是以检测目标为分类基础的，也就是说，凡是用于检测气体成份和浓度的传感器都称作气体传感器，不管它是用物理方法，还是用化学方法。比如，检测气体流量的传感器不被看作气体传感器，但是热导式气体分析仪却属于重要的气体传感器，尽管它们有时使用大体一致的检测原理。

AS8903 (2 1) Gas detector gas detector
Product features
Gas detection instrument is the instrument tool for gasleak detection, mainly refers to the portable / handheldgas detector. The main use of gas sensor to detect thegas species present in the environment, the gas sensor is used to detect the composition and content of gas.Generally, the definition of gas sensor is to detect targetclassification based, that is to say, every sensor for detecting gas composition and concentration are known as gas sensors, whether it is physical method, or bychemical method. For example, detection sensor of gas flow was seen not as a gas sensor, but the thermal conductivity gas analyzer is gas sensor is important,even though they sometimes use the detection principle of roughly the same.
