Hanna 1500PPM Calibration Solution

TDS solution are produced with high-quality potassium chloride in various concentrations. They are standardized using a conductivity meter calibrated with NIST potassium chloride.

The 1413 ?S/cm solution is the one best suited for general use. This solution is also available in combination kits with the pH 7 buffer for the easy calibration of multiparameter instruments.
