Description: This pH controller utilizes a microprocessor to monitor and control pH levels in aquatic systems. Unlike other controllers, this one has two independent 5A relay systems. One relay will turn a device on if the pH goes below a preset point. The other activates if the pH goes above a preset point. Controllers feature easy calibration, turn screw set point adjustment and relay indicator lights. Includes pH probe w/10' cable, calibration pouches and a 5' 115V/60 Hz power cord.

I have used the unit for more than two years, no problems. The readings are always spot on, no drift at all. I am still using the original probe, did not even recalibrate, still it gives very fast response.
