Product Specification

Reference radiometer MUV 2.4 WR with DVGW and/or ÖNORM sensor

MUV 2.4 WR Reference Radiometer Description
The UV measuring device MUV2.4WR in connection with UV sensors is designed as a reference measuring unit according to DVGW/ÖNORM. It is set for the check-up of UV systems which are used for drinking water disinfection. Based on comparison measurements between field sensor and reference sensor, it is possible to figure out, whether the field sensor must be re-calibrated or exchanged.

A closed sturdy metal housing protects the unit against external hazard and ensures the IP65 degree of protection. The device is run by rechargeable batteries, equipped with a LCD display with backlight, automatic measuring range changer and can be controlled easily by only 3 buttons. Battery recharge and power supply can be done by a wall power supply and it is possible to connect a printer or computer. The measuring device comes in a transport case.
