UVRRM

Reference UV Radio meter RRM according to DVGW and ÖNORM

The Reference Radiometer RRM is designed to check and recalibrate duty sensors for water sterilisation systems according DVGW and ÖNORM. This mobile radiometer consists of a handheld unit with sensor type selection switch and two sensor heads.
The sensors are built according to DVGW W294-3 and ÖNORM M5873.
They are identical in construction with the duty sensors.
The radiometer is calibrated to microbicidal weighted irradiance at λ = 254 nm against a PTB traceable standard. Medium pressure calibration can be done on request.
