The HI70038P solution is an analytical-grade TDS calibration solution at 6.44 g/L, intended for the verification and calibration of total dissolved solids measuring instruments. It ensures reliable and reproducible measurements.
The solution is standardized using a conductometer calibrated with NIST 2202 SRM potassium chloride, in demineralized water for analytical use, in accordance with ISO 3696 and BS3978 standards.
The preparation uses certified equipment, including verified weight scales, class A glassware, and certified thermometers, guaranteeing high precision of the calibration value.
The packaging in individual sachets is particularly suitable for users who do not perform frequent calibration as well as for field use due to its excellent portability.
Each sachet contains a fresh solution, protected by a light-blocking package to prevent UV-related alteration. Each unit is identified by a batch number and an expiration date ensuring complete traceability.
