Hanna HI98128 pHep®5 | Waterproof High-Resolution pH & Temperature Tester

Small pH changes can matter in laboratory work, water treatment, and quality control, so a basic 0.1 pH tester may not provide the detail you need. For finer portable measurement, we recommend the Hanna HI98128 pHep®5 with 0.01 pH resolution.

The tester measures -2.00 to 16.00 pH with ±0.05 pH accuracy and supports automatic calibration at up to three points. This makes it easier to check performance across acidic, neutral and alkaline samples. Its built-in temperature sensor automatically compensates pH readings from -5.0 to 60.0°C. A stability indicator tells you when to record the result, while the waterproof body suits wet work areas. The replaceable HI73127 electrode also helps reduce long-term replacement costs.

Calibration Tip: Use two or three calibration points when your samples cover a wide pH range. Buy Hanna HI98128 from Kamadi Pakistan for accurate portable pH testing.
