Lab Expo offers Benchtop pH Meter 25-BPM102 a high-performance pH meter with a large LCD to read pH & temperature measurements. With a -1.00 to 15.00 pH range it is suitable for daily measurement of pH in research laboratories as well as water quality testing units. Automatic calibration can be performed at 1-3 points using standard USA or NIST pH buffers. It offers automatic or manual temperature compensation of pH measurements.
