Product information "HI98172 ISE/pH/ORP/°C Meter with CalCheck"

  • pH Calibration Check™
  • Five point pH calibration with seven standard and five custom pH buffers
  • Log on demand (500 samples)
  • User-selectable “calibration time out”
  • Tutorial messages on LCD
  • PC interface via USB


HI 98172 is a pH/ORP/ISE meter housed in a waterproof casing. Up to five point pH calibration is available with seven memorized pH buffers and five custom pH buffers to provide users with the flexibility necessary to adjust the calibration range to obtain the most accurate and precise readings.

Exchange out the pH sensor for an ORP sensor to obtain mV readings. ISE sensors are calibrated up to five points and measurements are displayed in ppm.

Calibration Check™ incorporates an electrode condition graph which alerts the user with regards to the electrode status. If readings are taken too far outside the calibration range, the unit will warn the user with a graphic signal. Users may set a reminder to notify when calibration is due.

HI 98172 features tutorial messages on the LCD and an auto-end mode to ensure readings are taken only when they are stable. Comprehensive GLP data are directly accessible by pressing the GLP key and log-on-demand holds up to 500 records. Data can be transferred to a PC via USB with optional HI 92000 software and HI 920014 USB connection cable.
