I tried measuring supposedly saturated kalkwasser with my TDS meter (TDS-3 from HM Digital). I got a reading of 260 x10 (2600ppm).
According to other threads on this forum a fully saturated kalkwasser solution should read approx. 5150ppm TDS.
I also tried to put 2 teaspoons of kalk in a glass of water. This should ensure a fully saturated sample. My TDS meter is still reading max 2600 ppm.
Is my TDS meter defective?
