UV PANEL METER RM-31

The mains-driven panel meter RM-31 provides a continuous and precise measurement of irradiances of lamps, especially in UV systems. Different UV and visible spectral ranges can be controlled with the corresponding UV sensors.

The RM-31 works as a UV monitor and lamp control. The device displays the current irradiance on a 0% to 100% scale and also the lamp condition with three colored LEDs. Two alarms (warning and failure) are available on relay contacts and can be used for process monitoring. An additional analog signal can be used to control the lamp power.
