The mV monitor is a precision instrument for controlling permanently the redox potential in aquaria. The LED display continuously shows the current redox value of the aquarium water. The measuring range covers mV-values from -1,999 to +1,999. A 230 mV test solution, available as an accessory, allows checking and adjusting the electrode that is connected to the mV monitor via a BNC connection.
