Auto-calibration Bench pH/mV Meter

A microprocessor based pH, mV and temperature benchtop meter featuring an extra large LCD that displays pH or mV and temperature simultaneously. The extra large LCD (6.25” x 1.5”) can be viewed from a distance in a lab.

This instrument can measure pH from -2.00 to 16.00 and can be calibrated at 1 or 2 points using 5 standard buffers. During calibration, prompts on the LCD guide the user through the process. Temperature compensation of the pH measurement can be automatic or manual between -9.9 to 120°C. The dual mV range (±399.9 or ±2000 mV) can be used for ISE measurements, ORP measurements or to check the offset and slope of the pH electrode. Other features include a measurement memory function and a reading stability indicator.

The meter is supplied with a glass body combination pH electrode, temperature probe, electrode holder, power adapter and instruction manual. Buffer solutions are included to get you started. The meter has a 2-year guarantee (6 months for the electrode and probe).
