Johnlen pH Controller

Johnlen pH Controller

CS077-1 Johnlen pH Controller, with pH electrode included, determines the pH of your aquarium, with an accuracy of 0.03pH, without the need of copious testing, but the pH controller has the unique ability to control the pH of your aquarium. This is due to the unique HI/LO function that has adjustable max/min pH which, when connected to a signal sensing Automatic Dosing Pump  (CS077-2), will send a signal to allow for dosing of an according solution that will either increase or decrease pH levels in your aquarium automatically. The pH controller and electrode hanging attachments are included.
