Tried every little trick to clean my Aperia pH tester......damn thing will not calibrate right.....7.5 in the 7.0 solution and 4.5 in the 4.0 solution.....pool test kit had my res at about 7 and the Aperia said 7.6...so figure it has drifted up.....downed it till the pool kit said 6 and the Aperia said 6.4......ordered a GH test kit till I can figure out what pH tester I want to buy next....damn Aperia only lasted a year...
