Ingsoc Reviewed by Ingsoc on . pH controller recommendations Can anyone please give me some suggestions for a good all in one pH controller. My requirements are that it includes two dosing pumps (1 for up and 1 for down), can interface with a PC for remote access and data logging. Also the probe should be included as well. Also if you have any recommendations for a similar unit that does EC/TDS that would be appreciated too. :S5: Rating: 5
