1、 Product Overview

GT-SY-2X00 series industrial and commercial point type combustible gas detectorThe gas detector developed by our company according to the latest national standards adopts a 32-bit high-performance main chip and an advanced, reliable, and stable sensor combination design, manufactured using SMT surface mount technology. When the instrument is working, the sensor samples the gas and transmits the data in real-time to the high-speed processing chip for real-time analysis and processing. Then it is transmitted in real-time to the main chip, which processes it into switch signals, analog signals, or digital signals for users to choose from. This instrument can still continuously detect gases in unmanned hazardous environments and can be widely used in all places where there may be dangerous explosive gases, such as petroleum, chemical, smelting, pharmaceutical, oil fields, oil depots, storage, environmental protection, fire protection, municipal, etc. It is an ideal monitoring instrument to ensure personal safety and equipment safety.
