The Hanna Combo HI98131 is a pocket and waterproof pocket tester that measures pH, conductivity (EC), TDS (ppm) and temperature. The modern and compact design make is ideal for field measurement: this meter easily fits in your hands or in a pocket. The large LCD displaying pH, EC, TDS and temperature enables clear reading of the results. The HI98131 meter is the ideal 3in1 device to measure pH, Conductivity, TDS and temperature with a single instrument. This combo meter is very convenient and versatile tool for agronomists and producers to check the characteristics of soil solution, water samples or nutritive solution in hydroponics, greenhouse and agriculture applications. The pH results have a pH resolution of 0.01 with an accuracy of +/-0.05 pH, while the EC and TDS readings are displayed with a 0.01 mS/cm and 10 ppm (mg/L) resolution and 2% full-scale accuracy. The EC range of the HI98131 is from 0.01 to 6.00 mS/cm and TDS is from 0 to 3000 ppm.


Package includes: 1.5V battery (4 pcs.) • Instruction manual • Quality Certificate • HI73127 pH Electrode • HI73128 Electrode removal tool • Electrode Cleaning Solution sachet (1 pc.) • Quick Cal pH and EC one-point calibration solution sachet (4 pcs.
