Test and Measurement Forum

Hi all,
I want to design a PH datalogger with the output is linear with voltage. I want to know whether the output of PH sensor linear with voltage or not.
Best Regards,

Hi

The output of the PH sensor is not linear. The DrDAQ uses a look-up table used to convert the measured voltage to a PH value.

I believe this is the case for all PH sensors / measurement devices.
