PH meter issue: The PH values are all low

2009-02-15View Original

Thread Content

Problem with pH meters? We use Honeywell pH meters, and after calibrating them using buffers with concentrations of 6.86 and 9.18 and verifying the readings, the pH values obtained during online measurements remain low (they used to be around 9.30; now they are around 8.70). This has been a problem that hasn’t been explained yet, and it applies not just to one particular meter but to all online pH meters. Last edited by Welcome on 2009-2-15 13:15]
