HI 122
pH Meter with Calibration Check ™ Professional, automatic data storage and built-in printer

HI 122 complements the wide range of products that HANNA proposed for the measurement of pH. In this instrument are enclosed all the features most important to make a reliable measurement.
addition to basic functions such as micron resolution and automatic temperature compensation, is the Calibration Check ™ system for assessing the state of the electrode being calibration; the combination of this feature the possibility to construct a calibration curve to 5 points in the calibration phase, makes this product suitable for any type of application, whether working at pH neutral pH to extremely acid or basic; if this is not sufficient, one can intervene manually to insert one or two additional points.
The instrument is capable of storing the measurements carried out together with the data of the corresponding calibration; these data acquired yearly can be printed thanks to the built-in printer to the instrument, as well as be transferred to a PC via RS232 serial port.
