TDS Calibration

[Jason McK]

Just wondering what solution do you use to cal your TDS meter. I have the In-Line unit and believe it needs to be calibrated

Hey there J I didn't think that they needed to be calibrated. I have a inline one too that is connected to my RO/DI lines one going from the membrane out and one for the DI out. Let me know what you come up with ok.. I might have to calibrate mine too. Had it for like 2005 til now and never new that it had to be calibrated...:sad:
