Multi-Channel Gas Monitoring System

Datasheet

RM-590 Whether its in a chemical plant or engineering application, the model RM-590 provides continuous gas monitoring in hazardous locations.

The system is available in either a 4, 6, 9, or 12 channel wall mount housing making it easy to fit custom space requirements.

The brilliant three color bar graph display is quick and easy to read even from long distances. The RM-590's display changes colors, from green to orange to red, when the alarm set points are activated. For system flexibility, a built-in output signal of 4-20 mA can be used to interface with your existing Programmable Logic Controllers (PLC). The RM-590 is compatible with the widest range of detector heads providing the widest range of detectable gases in the industry. Detector heads can be either diffusion or sample drawing style which will ensure the most accurate delivery of samples given your particular facility or application.
