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.
This document is the instruction manual for the Hanna Instruments HI 98140 and HI 98150 Portable Waterproof pH/ORP Meters. These instruments feature IP 67 waterproof protection, GLP capabilities, and utilize intelligent electrodes that memorize calibration data to ensure measurement safety and efficiency.
