D.O.A By Therepairman909 on 8/19/2013Therepairman909 wouldn't recommend this product to a friendDOA !! Controller would not calibrate. PH climbs to its Highest value even after calibration setting is turned back. Example: PH reading 12.1 with probe sitting in a 4.0 calibration fluid.. Sent back to Milwaukee and waiting on replacement. Hopefully their replacement will do a better Job.
