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.
