Professional Lab pH ORP Temperature Data Logger

  • Widely used in laboratory, research & development, environmental studies.
  • During the pH mode, Up to 5 points push-button calibration with auto-buffer recognition.
  • Expanded memory stores and recalls up to 500 readings.
  • Selectable pH buffer standards and temperature units.
  • Automatically calculates and displays electrode slope after calibration.
  • Automatic Temperature Compensation (ATC) ensures highly accurate measurements 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 millivolt (R.mV) measurement provides accurate ORP readings.
  • Automatic endpoint function freezes the stable measured values for easy reading and recording data.
  • Manual temperature calibration provides accurate temperature value.
  • Help message as a 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 to allow all settings back to factory default values.
  • Built-in real-time clock stamps stored data to meets GLP standards.
  • Stored data can be transferred into computer via USB communication
