Detailed Product Description

Fixed Gas Detection Description
GTQ-WD6200 fixed gas detection is designed for industrial use. By adopting high-performance gas sensor and MCU technology, combined with sophisticated SMT manufacturing process, this detector has good repeatability, high accuracy and long lifespan.

The detector is widely used in oil refineries and chemical plants in the petroleum and petrochemical industries, as well as industries where flammable gases may cause explosions such as metallurgy, electric power, gas, catering, and aquaculture.

Fixed Gas Detector Detection Method
Natural diffusion is to use natural air flow to slowly flow the gas into the instrument for detection as the air flows freely, so as to obtain the results. Natural diffusion can accurately check whether the air contains toxic and harmful substances in real time. It is generally used in open places, such as open workshops. This method is affected by the detection environment, such as ambient temperature, wind speed, etc.

Fixed Gas Detection Key Features
