1382 PPM using a 0.5 conversion factor at 25C.
The conductivity solutions are made of high quality Potassium Chloride with different strengths. The solutions are standardized with a conductivity meter, calibrated by high purity NIST 999 Potassium Chloride in deionized water. The concentration is also confirmed by NIST 2201 Standardized Silver Nitrate solution.
