Advance Microprocessor pH/ORP Meter (LI-1122 pH)

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.
Automatic temp. compensation (ATC) ensures highly accurate measurement over the entire range.
Calibration due reminder prompts you to calibrate the meter regularly.
During ORP mode, single point offset calibration allows user adjusts displayed value to a known standard.
Absolute or Relative milli volt (R. mV) measurement provides accurate ORP readings.
Automatic endpoint function freezes the stable measured values for easy reading and recording data.
Help message as an operational guide to helps you understand how to use meter.
Setup menu lets user customizes buffer standards, calibration points, stability conditions, resolution,

Temperature units, date and time to meet measurement requirements.
