Hanna HI98129 | Waterproof pH/EC/TDS Tester – Low Range

The Hanna HI98129 Combo Tester combines pH, low-range conductivity, TDS and temperature measurement in one waterproof pocket instrument. It is designed for routine checks of drinking water, reverse-osmosis systems, aquariums, hydroponic solutions and other samples where conductivity remains within the microsiemens range.

The tester measures pH from 0.00 to 14.00, conductivity up to 3999 µS/cm and TDS up to 2000 ppm. Automatic temperature compensation supports consistent readings as sample temperature changes, while the adjustable EC temperature coefficient and TDS conversion factor allow better alignment with different water types. Its graphite conductivity probe resists contamination from salt deposits, and the exposed temperature sensor improves response time. The replaceable HI73127 pH electrode means the complete tester does not need replacement when the sensing cartridge reaches the end of its service life.

Water Testing Tip: Rinse the probe with a small amount of the next sample, immerse it to the correct level and wait for the stability indicator before recording results. Buy Hanna HI98129 from Kamadi Pakistan for convenient multi-parameter water testing and dependable technical support.

Low-Range Combo Tester Selection Guide

Choose the HI98129 for low-to-medium conductivity water up to 3999 µS/cm and TDS up to 2000 ppm. Select the HI98130 instead when testing concentrated nutrient, brackish or process-water samples.
