The HI 98140N is the most innovative portable pH meters ever offerred.

This instrument features IP67 waterproof protection, GLP (Good Laboratory Practice) capabilities and use Hanna's intelligent electrodes. 

This electrode incorporates a chip which memorizes the calibration data performed with a specific instrument. When the "intelligent electrodice 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 measurement readings in the event that the pH electrode is substituted after calibration. This electrode is equipped with a built-in temperature sensor; no need for an additional probe here!

By pressing a button, these meters can store up to 500 measurements complete with date and hour. Stored data can be displayed later or downloaded to a computer through an RS232 serial port and the HI 92000 Windows^® compatible software.
