pH Calibration Check™

  • Electrode response time
  • Five pH calibration points
  • Seven standard and two custom buffers
  • Out of calibration range warning
  • Large, custom LCD
  • Built-in impact printer
  • Automatic data logging of 2000 records and log on demand
  • GLP capabilities
  • High and low audible alarms


HI 122 is a benchtop instrument featuring a built-in printer, Calibration Check™, electrode response time and condition monitoring, and enhanced diagnostic messages during calibration.

This meter uses HANNA’s “P” series of electrodes. For more accuracy, these meters also check if the measurement is outside the calibration range and warns the user in case measurements are too far outside the calibration points. Calibration can be performed in up to five points using the standard seven buffers that are automatically recognized, or by using two custom buffer values. The buffer(s) used during calibration are displayed on the LCD even when in measurement mode.

Users can log on demand up to 50 samples (50 samples per channel for dual channel model). These meters have automatic data logging of up to 1000 points (1000 points per channel for dual channel model) with flexible starting and stopping criteria.

This instrument provides GLP capabilities that allows for the storage and retrieval of all data regarding pH, rel mV, EC and NaCl calibration as well as data regarding the maintenance and status of the electrode.


The built-in impact printer incorporated into the HI 122 uses regular paper that does not fade with time. A complete set of information based on the measured, set or recorded data can be printed on demand (for current reading in measurement mode, GLP and SETUP modes) or automatically (for autolog and log on demand modes). These models also allow users to print detailed information in four languages for specific help screens and instrument set-up.
