Azzota® Precision Benchtop pH Meter (mV/ºC/ºF & ORP included)

Precision benchtop pH meter, 1 to 5 points calibration, Automatic Temperature Compensation, setup menu contains 9 options, accuracy: 0.002pH.

pH Mode:

  • Precision benchtop pH meter is equipped with a large backlit LCD display.
  • 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
  • The automatic electrode diagnosis shows the pH slope and offset.
  • Automatic temperature compensation ensures accurate readings over the entire range.
  • Auto-Read function senses and locks the measurement endpoint.

ORP Mode:

  • 1 point offset calibration allows adjusting the displayed value to a known standard.
  • Relative and absolute millivolt modes provide reliable ORP measurements.



  • Calibration due alarm prompts the user to calibrate the meter regularly.
  • Setup menu allows setting the pH buffer group, the number of calibration points, resolution, stability criteria, date and time, auto-power off, etc.
  • Reset function automatically resumes all settings back to the factory defaults.
  • Expanded memory stores or recalls up to 500 data sets.
  • USB communication interface for data transfer and timed interval readings.
