We have a problem in PH Measurement with PH Transmitter from Yokogawa (Flexa). The problem is, we already calibrate the PH Tx with 4,7,10 PH Buffer, and then we've compared to the PH Meter Portable, when measuring the Buffer (4,7,10) the PH Tx and Portable PH Meter shown a same number, but when we comparing to the Actual Water in Proccess, there's a deviation +- 1,5 between the PH Meter Portable and PH Tx.
Anyone in here have any advise?
Thankss
