pH/mV/°C Bench Meters
Models pH212 & pH213

With a resolution selectable between 0.01 and 0.001 over the -2 to 16 pH range, the top-of-the-range pH 212 and pH 213 are designed for those users that require added accuracy. Both meters are supplied with optoisolated RS 232. The pH and temperature are displayed simultaneously and all pH measurements are automatically compensated for the effects of temperature. pH 213 also measures mV in the ±999.9 mV range when used with ISE and 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. pH 212 and pH 213 are supplied complete and ready-to-use with a laboratory-grade glass pH electrode, stainless steel temperature probe, electrode holder, 12 VDC transformer and calibration buffers.
