Detailed Product Description
Portable Gas Detector Description
BX171 is a disposable portable single gas detector that can detect H2S, CO and O2 with small size and firm configuration. It is mainly intended for individual used to detect a confined space or the working environment where dangerous gases existed and harm to personal safety. It is normally clipped on belt, lapel or breast pocket.
Portable Gas Detector Application
It can be widely used in the oil and gas industries, steelworks, chemical plant, mining,marine, power plants, sewage treatment plant, environmental protection, city construction, labs etc.
Portable Gas Detector Working Principle
Gas detectors can be divided into electrochemical gas detectors, infrared gas detectors, thermal magnetic gas detectors, semiconductor gas detectors, ultraviolet gas detectors, etc. according to the principle of gas sensors.
The model of this product is E6000, and the gas sensor type is an electrochemical sensor. Its working principle is that the gas diffuses into the sensor, reaches the working electrode through the back of the porous membrane, and is oxidized or reduced on the working electrode. The electrochemical reaction generates a current, which passes through the external circuit. In addition to measuring, amplifying, and performing other signal processing functions, the external circuit also maintains the voltage across the sensor (for a two-electrode sensor, the voltage is between the working electrode and the counter electrode; for a three-electrode cell, the voltage is between the working electrode and the reference electrode). At the counter electrode, a reaction of equal magnitude and opposite direction occurs, that is, if the working electrode is an oxidation reaction, the counter electrode is a reduction reaction.
