Help. I just calibrated new conductivity probe. (No temp probe so comp set at 0.0). Waited for dry measurement to settle. Selected matching solution type. Added probe to solution and waited for measurement to settle. Conductivity measures around 23... Shouldn't it be around 35 for salinity of 1.026 (which is what my tank measures with calibrated refractometer).
This is the second time I have calibrated. Both times same result. BYW, I rinsed the probe with Ro/Di water and allowed to dry overnight between attempts.
What's wrong?
Thanks
