Professional Benchtop pH/mV Meter with Built-in Printer


The HI122 is a professional pH/mV and temperature benchtop meter with a built-in printer. The built-in impact printer incorporated into the HI122 allows measurement information to be printed while in various modes. The meter comes with Hanna’s HI1131P glass pH electrode and the temperature probe HI7662-T to allow for automatic temperature compensation. The HI122 also allows for ORP measurements when used with the HI3131B ORP electrode (supplied seperately). The HI122 offers many features including CAL Check™, five-point pH calibration, data logging, comprehensive GLP data, and PC connectivity to provide users with a simple way to organize and manage their data.

•  Automatic Temperature Compensation
•  CAL Check™
•  Data Logging

Features at-a-glance :

Automatic Calibration
•  Auto pH calibration can be performed up to five points with seven standard buffers and two custom buffers.

  Build-in Impact Printer
•  The built-in impact printer incorporated into the HI122 uses regular paper that does not fade with time.
•  The information related to measurements being taken can be printed while in measurement mode, GLP or Setup mode.
•  This meter also allows users to print detailed information in four languages for specific help screens and instrument set-up.

  CAL Check™
•  Hanna’s exclusive CAL Check™ diagnostics system ensures accurate pH readings every time by alerting users of potential problems during the calibration process.
•  The CAL Check™ system eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated pH buffer solutions during calibration.
•  After the guided calibration process, the probe condition is evaluated and an indicator is displayed informing the user of the overall pH electrode status.

  Data Logging
•  The log-on-demand feature accepts the recording of 50 samples.
•  Interval logging allows up to 1000 data points to be recorded and allows the user to specify time intervals from 5 seconds to 180 minutes.

Data Transfer
•  With a built-in logging function, measurements are stored in non-volatile memory, and can be transferred to a PC through the RS232 port.

GLP Data
•  The calibration data for each channel including date, time, standards used, offset, and slope can be accessed at any time through the HI122 menu.

HI1131P pH Electrode
•  The HI122 is supplied with the HI1131P glass body, double junction, refillable pH electrode with an indicating sensor made of High Temperature (HT) glass.
•  The double junction and HT glass design allows the HI1131P to be used in a wide variety of applications ranging from samples with metals and Tris buffer
to samples at elevated temperatures.

 Temperature Compensation
•  Temperature for pH measurements can be compensated for automatically (ATC) or manually (MTC) from -20.0 to 120.0°C with the use of the supplied HI7662-T temperature probe.
