Vanguard Toxic and Combustible WirelessHART® Gas Detector

Wire Less. Save More!

The Vanguard Toxic and Combustible WirelessHART® Gas Detector was born to be wireless. With a 5-year battery and 1-button calibration — the Vanguard is a gas detector built for the wireless world!

The new Vanguard WirelessHART gas detector’s flexible monitoring of toxic or combustible gas can save lives. Its ultra-long battery life saves maintenance trips. Its easy pushbutton calibration; mount-anywhere mobility; and seamless, plug-and-play interoperability save time and trouble. And of course, eliminating long wiring runs saves thousands in installation costs.

Vanguard: It’s the way you always wanted wireless to work!


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), an electrochemical hydrogen sulfide sensor (0-100 ppm), or an electrochemical carbon monoxide sensor (0-500 ppm).

Wireless gas detectors like the Vanguard can augment existing gas detection coverage with minimal financial and labor outlay. The Vanguard can be plugged-and-played anywhere in an existing WirelessHART® mesh and perform its role as a first line of defense for gas monitoring.
