The Eutech/Thermo Scientific Alpha pH 560 pH controller is used alongside RO for the ultimate precision in water manipulation. The pH controller prevents pH crash when running RO on koi ponds.

Alpha pH 560 limit control meter simplifies the task of controlling several processes with two set-point relays. Separately adjustable high and low hysteresis ensures chatter-free signals, preventing false alarms and unnecessary down-times.

Use with the for best results. Can be used to operate the .
