What do you multiply the offset by when performing a Solitax turbidity calibration?
Solitax sc Turbidity Calibration
Negative one (-1). This value is missing from the current User Manual. The reason is that when you put the probe into the DI water your goal is to make the probe read zero. Therefor, if the probe is reading 5 NTU in DI water you will make an offset of -5. Then the probe will read zero in the DI water.
