Hanna precision pH meter
Model pH 212
Description
| General description | Selectable resolutions between 0.01 and 0.001 over a pH range of -2 to 16 designed for added accuracy. Large horizontal display shows both pH (or mV) and temperature at the same time. A stability indicator ensures a proper calibration. HI 1131B pH electrode, combination, glass, interchangeable, 1 m cable included. pH calibration: automatic 1 or 2 points with 5 memorized buffers (pH 4.01, 6.86, 7.01, 9.18, 10.01) |
| Help in selecting the correct electrode can be viewed at Electrode Selection Guide Hints on Electrode Maintenance |
