ODM Industrial and Commercial Gas Detector Shield SD2100A Series Manufacturer, Factory
Product Overview
The GTYQ-SD2100A series point-type gas detector (hereinafter referred to as the detector) is an intelligent bus and branch line product. It forms a gas alarm detection system with the matching controller to conduct real-time detection of target gases that may be present in the working environment. It displays the real-time concentration of the gas on-site, and when the concentration exceeds the limit, the controller issues an audible and visual alarm signal. The controller can monitor the normal, fault, or alarm status of the detector, and can also use the controller or remote control to perform zero point calibration, concentration calibration, and set parameters such as high/low alarm limits.
Application
This leak detector is widely used in the petroleum, chemical, environmental protection, metallurgy, refining, gas distribution, biochemical medicine, and agriculture industries
