The HI70023P is a premium quality 5.00 ppt salinity calibration solution prepared for precise salinity meter calibration. Each batch is standardised with a conductivity meter calibrated using potassium chloride NIST 2202 Standard Reference Material in deionised water for analytical use, in accordance with ISO 3696 and BS3978 standards. Preparation is completed using certified weight-checked balances, Class A glassware, and certified thermometers to ensure consistent performance.

Supplied in individual single-use sachets, this solution is ideal for occasional calibration and field testing where convenience and portability are important. The light-block foil packaging helps protect the solution from UV exposure, while each sachet is marked with a lot number and expiry date for complete traceability. Hanna calibration solutions are specially formulated to provide a shelf life of 5 years from manufacture when unopened.
