TUNZE® digital measuring instruments have been developed especially for use in aquarism. The instruments with their electrodes operate at a high accuracy and are comparable with laboratory instruments in quality. The clearly arranged operating panel with key pad and adjustment knobs ensure fast and easy handling. The controller comes with parts for two different types of wall mounting.

mV controller
(7071/2)

This pocket-sized measuring instrument has been designed to match the pH controller. The measuring instrument is mounted by means of two types of wall holding device. The electrode also comes with a universal holding device and thus solves almost all mounting problems. The controller is supplied with a long-life high-quality glass electrode, a cleaning solution and a 9V battery. The measuring instrument has been provided with an auto power off function so that the battery lasts for a very long time. Along with the switched socket outlet, the mV controller can be extended to a complete ozone control station, for example.

mV Controller Set
(7075/2)

This set consists of mV Controller 7071/2 and switched socket outlet 7075.12. The switching output has an Ohmic load of 1,800 W at 230 V (900 W / 115 V). The switched socket ouelt also serves as a power supply for the controller.
On account of the adjustable time interval metering system, a careful ozone distribution is possible to prevent an overdose.
