Detailed Product Description

Fixed Gas Detector Description

GTQ-WD6200 fixed point gas detector 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.

Fixed Gas Detector Application

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.

Different sampling method

Natural diffusion is that the gas in the detected area flows slowly into the instrument for detection with the free flow of air, and needs to be placed on site. This method is affected by the detection environment, such as ambient temperature, wind speed, etc., and is not suitable for gas sources with low pressure. The advantage is low cost.

 

The pump suction type is that the instrument is equipped with a gas sampling pump. Its working method is that the power supply drives the gas sampling pump to extract and sample the gas in the test area, and then the sample gas is sent to the instrument for detection.

The characteristics are fast detection speed, long-distance measurement of dangerous areas, and safety of maintenance personnel. It is suitable for occasions where the gas detector cannot be placed on site and has special requirements for reaction speed, pressure difference, etc.
