TDS meter Calibration

[houstonreefer]

I calibrated my meter but reading was not show the exact number of the calibate liquid. It was a little bit higer. Does it normal? and is it ready to use?

BTW it read my tap is 255, my RO/DI is 5.


Thanks in Advance

Did you purchase the calibration fluid make for your TDS meter. My Hanna uses 1382 ppm calibration fluid but it seems like each meter calibrates with different fluid.

Yes it does come with the same like you.
