| Hanna Part No: HI-121
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 calibraton buffers.
The 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 Check, good calibration results can be easily viewed directly on the display with the percentage information regarding electrode condition and response.
The HI-121 is in compliance with GLP. This meter 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.
The HI-121 is supplied complete with HI-1131P pH electrode, HI-7662-T temperature probe, pH4 and pH 7 buffers, electrolyte solution, 12 vdc power adapter and instructions.
