HI 98140 is a portable Calibration Check™ pH meter that utilizes HANNA’s SMART electrode technology.
SMART electrodes incorporate a chip, which stores the calibration data performed with a specific instrument. When the “SMART” electrode is attached to the meter again, it is automatically recognized. This allows the operator to optimize time and efficiency with unsurpassed safety. It also avoids erroneous measurements taken in the event the pH electrode is substituted after calibration.
