United Electric (UE) Vanguard WirelessHART Gas Detector for Methane, H2S, and CO

UE's Vanguard Toxic and Combustible WirelessHART® gas detector was designed and built specifically for safety applications where wiring is difficult. Its ultra-long 5+-year battery life saves maintenance trips. Its easy pushbutton calibration, mount-anywhere mobility, and seamless, plug-and-play interoperability save time and trouble. And eliminating wiring runs saves thousands in installation costs.

Each Vanguard detector has a WirelessHART transceiver, an antenna, a display, a long life power module, a gas sensor for hydrogen sulfide, carbon monoxide, or methane, and a signal processor for the gas sensor. Vanguard uses Flexsense, a trademarked sensor architecture that allows the sensor to identify its target gas and self-configure to a Vanguard transmitter on connection.
