mV controller without probe

Redox-potential (ORP) monitor and controller

The mV controller is designed for monitoring and controlling the redox potential (or ORP - oxidation-reduction potential) in aquaria. The unit has a broad controlling range from -500 to a +500 mV, and a measuring range from -1000 to +1000 mV. It can be used to control the supply of ozone in saltwater aquaria and / or for the control of nitrate removal in anaerobic biological filters (Nitratereductor). The unit is supplied with a BNC connection for a mV probe. 
The use of an original Aqua Medic plastic shafted electrode is recommended.
