This devicecombines the latest in gas sensor technology, using electrochemical, catalytic combustion, infrared, thermal conductivity, andphotoionization technologies to detect gases. It is ideal for industries suchas oil, chemical, and environmentalprotection.
The device integrates sensors that support real-time concentrationdetection for CO, H2S, O2, Ex, and CO2, and boasts excellent anti-interference capabilityand high measurement accuracy. It is designed in compliance with international safety standards, featuring explosion-proof, waterproof,and dustproof protection, and can be used in harsh environments such as high humidity, dust, and high temperatures.
Working Principle
The Nexisense BTYQ-MS500-5 Handheld Multi-Gas Detector integrates various advancedgas detection technologies, with each detection gas principle as follows:
Electrochemical Principle: Used fordetecting CO, H2S, O2, andother gases, utilizing the oxidation-reduction reaction of the gas onthe electrode surface to generate a current signal, which isconverted into gas concentration.
Catalytic Combustion Principle: Mainly used for detecting combustible gases(Ex), when the gas reacts witha catalyst, the heat generated is converted intoa signal via a thermocouple, indicating gas concentration.
Infrared Principle: Measures the absorption ofspecific wavelengths of infrared light by gasmolecules to determine the concentration of gaseslike CO2.
ThermalConductivity Principle: Usedto detect gases by comparingthe difference in thermal conductivitybetween the gasand air.
Photoionization Principle (PID): Used for detecting VOCs and other volatile organic gases, by ionizing the gas molecules with UV light and measuring the changes in ion flow to calculate the concentration.
