Aqua Medic Electrode Holder is designed to easily and securely hold four electrodes.
It can be attached directly to the side of the aquarium, to offer constant readings. The sturdy plastic housing will ensure that the delicate electrodes are able to offer the best results.
For an advanced system, take a look at the Aqua Medic AT Control System which is a modular system that can control a myriad of parameters in multiple aqauriums.
