pH/ ORP/ Temperature Meter with Built-in Printer HI 122

HI 122 is a benchtop instrument featuring a built-in printer, Calibration Check™ , electrode response time and condition monitoring, and enhanced diagnostic messages during calibration. This meter uses HANNA’ s “ P” series of electrodes. For more accuracy, these meters also check if the measurement is outside the calibration range and warns the user in case measurements are too far outside the calibration points. Calibration can be performed in up to five points using the standard seven buffers that are automatically recognized, or by using two custom buffer values. The buffer( s) used during calibration are displayed on the LCD even when in measurement mode.
