SKU: HI122-01

Ships within 1-2 Business Days

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 an HI7662-T temperature probe 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

The HI122 pH/mV and temperature benchtop meter features CAL Check, a clear and informative LCD display, data logging capability, and computer connectivity. The HI122 has a single input channel that allows for measurement of pH and ORP. Readings for pH can be manually or automatically compensated for temperature variations with the separate HI7662-T temperature probe from -20.0 to 120.0°C.

The HI122 can be calibrated up to five points with a choice of seven standard buffers or two custom buffers. All GLP data regarding pH and relative mV calibration is stored for the user to review when necessary. The built-in impact printer incorporated into the HI122 allows for on demand printing of a complete set of information based on the measured, set or recorded data while in various modes such as, measurement mode, GLP or Setup mode.

Features at-a-glance

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.

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

Built-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.

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.

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.

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.
