Overview

The GT-SY-2000 combustible gas detector (hydrogen) is a gas detector developed by our company in accordance with the national standard GB12358-2006 and combined with GB/T50493-2019. It adopts a 32-bit high-performance main chip and a reliable and stable sensor combination design, and is 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.

Product Details

1、 Product Introduction

Combustible gas detector (hydrogen)According to national standards for our companyGB12358-2006At the same time, combiningGB/T50493-2019The developed gas detector adopts32High performance main chip and reliable, stable sensor combination design, usingSMTMade with SMT technology.

Combustible gas detector (hydrogen)During operation, sensors sample gases and transmit real-time data to high-speed processing chips 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 places such as petroleum, chemical, smelting, pharmaceutical, oil fields, oil depots, storage, environmental protection, fire protection, municipal and other places where there may be dangerous explosive gases. It is a monitoring instrument for personal safety and equipment safety.
