ADVANCE MICROPROCESSOR pH/ORP METER
Product Code : LI-1122 pH
Product Description

LI 1122 pH is a high precision pH meter with backlit LCD display. The meter can displays many useful

Prompt messages to helps you quickly and easily measuring the samples.


SALIENT 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.

  • 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.

  • Reset function can resume all setting to factory default values.

  • Expanded memory stores and recalls up to 500 readings.

  • Built-in real-time clock stamps stored data to meets GLP standards.

  • Stored data can be transferred into computer via USB communication interface.
