Title: TDS Calibration Solution 20ppm
Post by: The Seven Bays Window Cleaning Company on November 25, 2008, 04:25:34 am

Found this on Ebay.

With the postage, works out cheaper than buying direct from RO Man.

I think you dip your TDS meter in and it should read 20 if it does not you adjust your meter until it does.

Im going to get some as i want to check my reading is right.

Well worth it.

I've bought two new meters recently, neither was calibrated correctly, one is so inaccurate it varies by over 14% depending on the TDS of the water tested :o
