MSR-Electronic PolyGard® ARB2 Stand-Alone Gas detector
PolyGard® ARB2 is a Stand-Alone type gas detector that senses oxygen, toxic gases, flammable gases, and vapors in spaces without danger of explosion and goes off alarms when it's dangerous.
It is possible to utilize various types of sensors, including EC, CAT, and IR sensors. The device offers outputs such as standard 4-20 mA analog output and relay function. An LCD display inside shows real-time gas concentrations, and it can be connected to sensors installed at distances of up to 500 meters.
