Pool Line pH Checker® HC - HI779

HI779 Pool Line pH Checker HC is a professional handheld colorimeter engineered for fast and reliable pH testing in pool and spa water. Combining the convenience of a chemical test kit with the accuracy of photometric instrumentation, this device is ideal for operators, service technicians, and facility managers who demand consistent water quality control.

This meter measures pH in the range of 6.3 to 8.6 with a high resolution of 0.1 pH and delivers results with an impressive accuracy of ±0.2 pH. It leverages a fixed wavelength LED light source at 525 nm and a sensitive silicon photocell to precisely determine absorbance and pH concentration, eliminating the subjectivity commonly associated with color disc test kits.

• Accurate digital pH measurement for pool and spa water analysis.
• Measurement range: 6.3–8.6 pH, resolution: 0.1 pH, accuracy: ±0.2 pH.
• Light source: LED @ 525 nm, detector: silicon photocell for stable readings.
• Adaptation of Phenol Red Method ensures specificity and repeatability.
• Simple one-handed operation with automatic shut-off after 10 minutes of inactivity.
• Supplied in a compact form factor (86.0 mm x 61.0 mm x 37.5 mm, weight 64 g) for easy storage and field use.
• Powers via a single 1.5V AAA battery for on-the-go measurements.
• No reagent mixing or manual color comparison required—digital readout prevents human error.
• Well-suited for routine pool maintenance, compliance verification, and spot checks in hotels, clubs, and public swimming facilities.
• Low-maintenance alternative to traditional pH meters and paper tests.
