Hanna 1500PPM Calibration Solution microbes Minimal impact on honey beesTDS 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.
