Hanna Instruments Laboratory Division has released the pH 212 and pH 213, bench meters for users that require added accuracy. They have a resolution that is selectable between 0.01 and 0.001 over the -2 to 16 pH range. The pH and temperature are displayed simultaneously and all pH measurements are automatically compensated for the effects of temperature.

The pH 213 also measures the mV range when used with ORP electrodes. The large horizontal display shows both pH (or mV) and temperature. Calibration can be at one or two points aided by automatic buffer recognition at pH 4.01, 6.86, 7.01, 9.18 and 10.01. A stability indicator ensures proper calibration and accurate measurements. Any particular measurement can be stored and recalled at a later time. The front label carries clear and concise information about how to operate the meter.

The pH 213 is supplied with an HI 1131B interchangeable pH electrode, an HI 76404 electrode holder, a 1m BNC cable, an HI 7669/2W temp. probe, pH 4 and 7 calibration solution, electrolyte solution and a 12V dc adapter.
