AreaRAE Steel is a multi-gas, wireless monitor. Housed in a stainless-steel enclosure, it is rugged, portable and weather resistant, ensuring that it can withstand harsh environments. The AreaRAE Steel can monitor up to five threats, including VOCs, LEL, Oxygen, and two user-selectable toxic sensors. Strategically placed AreaRAE Steel monitors can be used to quickly establish a perimeter, allowing individuals to back off to a safe position and receive readings from up to 2 miles (3 km) away.
