Hanna Instruments Pool Line pH Checker HC Calibration Verification Kit (HI779-11)

Hanna Instruments Pool Line pH Checker HC Calibration Verification Kit

The HI779-11 is a calibration verification kit designed to validate the performance of the HI779 Pool Line pH Checker HC handheld colorimeter — Hanna Instruments’ dedicated pH meter for swimming pools, hot tubs, and spas operating across the 6.3–8.6 pH range. The kit consists of two sealed, pre-tinted standard cuvettes that allow pool owners and technicians to quickly and confidently confirm their instrument is reading accurately. Every kit is supplied with a Certificate of Analysis for full traceability.

What’s included

The kit contains a sealed cuvette to zero the meter and a pre-coloured reference cuvette, together with a Certificate of Analysis that states the lot number, the reference values and the expiry date. Together, they provide a performance check of the HI779 Checker HC without any additional reagents or equipment. The standards are reusable and have a long shelf life. Full instructions for use are included in the kit.

Compatibility

The HI779-11 is the dedicated calibration verification kit for the HI779 Pool Line pH Checker HC. It is not intended for use with other Hanna Checker HC models. Because the HI779 uses a colorimetric adaptation of the phenol red method, routine verification with the HI779-11 is the recommended best practice to maintain measurement confidence — no traditional pH meter calibration is required.
