mV computer-Set The mV computer-Set uses the same microprocessor technique as the pH Computer-Set. Waterproof touch keys are used to set the required values and calibrate the electrode. The mV computer-Set is ideal for controlling anaerobic biological filters such as the Nitratereductor which have negative redox potential or can control the supply of ozone to the...

mV 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...

pH computer-Set Microprocessor controlled pH monitor and controller The pH computer-Set utilises a modern microprocessor, which provides high precision measurement and control. The pH computer-Set is used to control precise values of pH in the aquarium or the Calciumreactor. The computer can switch up to 500 watts using the supplied external electrical...

pH controller (without probe) pH monitor and controller The pH controller is a precision instrument for controlling the pH value in aquaria. In combination with a CO2 system and a solenoid valve the pH can be maintained at a constant level, and the CO2 supply to aquatic plants or into a Calciumreactor can be controlled. The unit is supplied with a large LED...

Conductivity meter LF controller Conductivity monitor and controller The salt content of water can be determined by measuring the electrical conductivity. A special feature of the LF controller conductivity monitor and controller is the broad measurement and control range which is divided into 2 bands: from 0 to 2000 μS, the unit is used for monitoring...
