Vanguard Toxic & Combustible Gas Detector

Brand: United Electric Controls Ltd

The device is an explosion-proof and intrinsically safe, WirelessHART point gas detector used for the detection and monitoring of harmful gases in air, in order to help maintain a safe environment. A field-interchangeable gas sensor module provides detection of hydrogen sulfide (H2S) or methane (CH4) gas.

Gas measurement readings in parts per million (ppm) or lower explosive limit (%LEL) are communicated along with network and battery status via a local, digital display, and WirelessHART 7.2 communication protocol. The device seamlessly integrates with existing supervisory control and data acquisition (SCADA) or asset management (AMS) systems.
