GDC series combustible gas detector / gas detector

GDC series combustible gas detectors/gas detectors are made of high-performance imported gas-sensitive elements, combined with Gewee’s patented intelligent sensor technology and zero-point temperature compensation technology. They are accurate in detection, sensitive in response, have good temperature and humidity characteristics and linear output, and are easy to operate, easy to maintain, and have clear display. They are particularly suitable for use in industrial places with complex environments and strict requirements such as petroleum, chemical, metallurgy, electric power, pipe corridors, and laboratories.
