Abstract

The invention relates to technologies for testing or analyzing gas, in particular to a detector for multiple types of gas. The detector can detect concentrations of multiple types of gas at the same time. The detector for multiple types of gas comprises a shell, a detection box, a gas inlet pipe, a gas outlet pipe, a lower computer and a control computer, wherein a plurality of electrochemical gas sensors are arranged in a cavity inside the detection box; the gas outlet pipe is provided with a sampling pump. The detector has the advantages that the multiple electrochemical gas sensors are provided and can detect concentrations of multiple types of gas at the same time, so that it is achieved that one device detects concentrations of multiple types of gas at the same time. The detector is particularly suitable for occasions with the limited space and needing to measure multiple types of gas.

Description

technical field [0001] The invention relates to testing or analyzing gas technology, in particular to a multi-gas detector. Background technique [0002] A gas detector is an instrumentation tool for gas leakage concentration detection, mainly referring to a portable / handheld gas detector. Gas sensors are mainly used to detect the types of gases existing in the environment. Gas sensors are sensors used to detect the composition and content of gases. It is generally believed that the definition of gas sensors is based on the classification of detection targets, that is to say, any sensor used to detect gas composition and concentration is called a gas sensor, regardless of whether it uses physical methods or chemical methods. [0003] Most of the traditional gas detection instruments are single gas or fixed gas type single gas detection instruments; the detection gas type is single and fixed; there is no historical data record. For example, a common single-point gas detecti...
