OVERVIEW
One gas, monitored with precision
The RBR-1x portable single-gas detector is a compact, high-performance device designed to monitor individual concentrations of oxygen (O2), carbon monoxide (CO), combustible gases (LEL) or hydrogen sulfide (H2S).
It incorporates high-sensitivity sensors — powered by City Technology (a Honeywell company) and Alphasense sensor technology — ensuring reliable and accurate performance even in the most demanding environments.
Featuring a compact and rugged design, the device offers IP67 protection and an explosion-proof rating of Ex d IIC T3, making it a reliable solution for use in harsh and hazardous conditions.
- Oxygen (O2)
- Carbon monoxide (CO)
- Combustible gases (LEL)
- Hydrogen sulfide (H2S)
