Stand Alone  or Network Toxic and Explosive Gas Monitoring

Serving as the sensor in a gas detection network, the VA-201T provides accurate readings of toxic and explosive gas levels through its RS-485 communication link with the VA-201C Vulcain Controller, or directly back to a DDC or BMS through a 4-20mA output.
