RAE Systems AreaRAE Inert RAE Systems Get Quote



AreaRAE Inert is a one- to five-sensor gas detector equipped with a wireless RF (radio frequency) modem which allows the unit to communicate real-time sensor readings with a remotely located host controller PC. Wireless remote monitoring ensures worker safety, while sensitive sensing technology measures toxic and flammable gases in inert atmosphere without the need for dilution fitting.
