RBR-4x
Four-gas portable detector for O2, CO, LEL and H2S with color display and data logging
Compact, rugged and simple to operate, built for reliable detection in demanding environments.
- 4 gases O2 · CO · LEL · H2S
- Ex d IIC T3 Explosion-proof · CE
- Up to 10 h Continuous operation
OVERVIEW
Four gases, one compact instrument
The RBR-4x portable multi-gas detector is a compact, high-performance instrument designed to monitor concentrations of oxygen (O2), carbon monoxide (CO), combustible gases (LEL) and hydrogen sulfide (H2S).
Operation is simple and intuitive through a four-button interface, allowing quick and efficient use in the field. Its color LCD display provides clear and immediate identification of each detected gas, while built-in data logging records up to 9,600 data points that can be downloaded to a PC via USB.
The rugged, water-resistant housing ensures reliable performance in demanding environments, and its high-sensitivity sensors — powered by City Technology (a Honeywell company) and Alphasense sensor technology — deliver accurate, dependable detection even under challenging conditions.
- Oxygen (O2)
- Carbon monoxide (CO)
- Combustible gases (LEL)
