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.
