Single Gas Detector A single-gas detector is a device that detects the presence of any gas within an area, usually as part of a safety system. This type of Single-Gas Detector Equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. A gas detector can also alert operators in the vicinity of the leak, allowing them to leave the area. We supply an immense choice of gas finders and screens for various applications like oxygen, combustible gases, and carbon monoxide. The gas detector adopts an embedded MCU controller detector adopts and is easy to operate, These units can be provided with sensors to recognize the most well-known gases as well as a scope of more extraordinary gases for changing applications. VS-70 xx portable gas detector locators are additionally accessible with a PID sensor to identify the presence of volatile natural compounds and with infrared IR sensors for the estimation of CO2 and other combustible gases. FEATURES : Single gas detector individually we can provide gas detectors for the following gases: Oxygen Combustible Gases LPG Hexane Hydrogen Carbon Monoxide Hydrogen Sulphide Chlorine Sulfur Dioxide Ammonia Hydrogen Chloride Hydrogen Nitric Oxide Nitrogen Dioxide Ethylene Phosphine Phosgene Ozone And Many More
