Update: 28 September, 2023

HI 98140 and HI 98150 are two of the most innovative portable pH meters ever offered. These instruments feature IP 67 waterproof protection, GLP (Good Laboratory Practice) capabilities and use the HANNA instruments®’ intelligent electrodes. These pH electrodes incorporate a chip which memorizes the calibration data performed with a specific instrument. When the “intelligent” electrode is attached to the meter again, it is automatically recognized. This technology allows the operator to optimize time and efficiency with unsurpassed safety. It avoids erroneous measurements taken in the event the pH electrode is substituted after calibration.
