• Calibration data (buffer values, expiration date)
• Date and time
• Multi-language interface
• ID number
• Manual or automatic temperature compensation
• Temperature measure unit (degree K, °C, °F)
• Relative mV scale
• Incremental ISE methods
• Auto end point mode
• Data logging

The two measurement channels of the HI 4212 are galvanically isolated to eliminate noise and instability. In ISE mode these instruments provide the user with a choice of several incremental methods. Communication is via opto-isolated USB and RS232 ports.

HI 120• HI 121 - Professional pH Meters with Calibration Check and Automatic Data Logging

When pH measurements need to be performed, the calibration phase is very important. It is often necessary for the user to measure extreme pH values or values far from standard calibration buffers.

HI 120 and HI 121 can offer help in these situations, thanks to automatic calibration in up to 5 points. Users can select each point from among the 7 factory stored values and up to 2
more values manually entered for specific applications. Moreover, thanks to Calibration CheckTM, good calibration results can be easily viewed directly on the display with the percentage information regarding electrode condition and response. Both meters are in compliance with GLP. HI 121 can also perform ORP and ion-selective measurements, and store data that can be easily downloaded to a PC thanks to an RS232 port and our optional HI 92000 software.
