View Full Version : Need Help Calibrating TDS Meter

07/14/2008, 05:22 PM
Hi, I have the following TDS meter and I accidentally changed the calibration after I got it. I read in the manual that there were a few ways to calibrate it using different fluids, but couldn't find anywhere to buy the fluids that the manual talked about.


I did, however, notice that there is an EC mode (electrical conductivity???) and I happen to have a solution that is used to calibrate my PinPoint salinity monitor (53 mU, I think) and was wondering if there was a way I could use that solution to calibrate my TDS meter? Thanks in advance for the help.

You can get TDS calibration solution if you haven't found that out by now. Kind of an old post I guess... maybe it'll help someone else. :D

Interesting. I don't know why but I never thought to look for TDS solution fluid before. I still don't feel the need to run out and buy it, but at least I know that it's available if I ever need to verify my TDS readings.
