  Toxic and combustible Wireless Hart® gas detector   
your inquiry


The Vanguard WirelessHART® gas detector is ideal for the monitoring of toxic and combustible gases without the need for costly and fixed wiring. With a five year battery life and one button calibration, the Vanguard  detector is easy to operate and maintain.

Each Vanguard detector has a
WirelessHART® transceiver, an antenna, a display, a long life power module, a gas sensor, and a signal processor for the gas sensor. Vanguard uses a sensor architecture trademarked “Flexsense,” which allows the sensor to identify its target gas and self-configure to a Vanguard transmitter upon connection.

It is currently available with either a non-dispersive infrared (NDIR) methane sensor (0-100% LEL) or an electrochemical hydrogen sulfide sensor (0-100ppm).
