Features:

During the pH mode, Up to 5 points push-button calibration with auto- buffer recognition.
Selectable pH buffer standards and temperature units.
Automatically calculates and displays electrode slope after calibration.
During ORP mode, Single point offset calibration allows user adjusts displayed value to a known standard.
