Product Details

1、 Product Introduction

GQ-SY-2X00 new national standard toxic and harmful gas detector point type gas detectionThe gas detector is developed by our company based on 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.

GQ-SY-2X00 new national standard toxic and harmful gas detector point type gas detectionWhen the sensor is working, it 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 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.
