- Packaging has been designed to keep air and light from damaging the solution
- TDS solutions are produced with high quality potassium chloride in various concentrations
- They are standardized using a conductivity meter calibrated with NIST potassium chloride
- TDS value: 1500 ppm (mg/L) at 25 degree C
- TDS conversion factor 4-4-2: 0.65 ppm = 1 microsiemens/cm (approximately)
