Keterangan :

With a resolution selectable between 0.01 and 0.001 over the -2 to 16 pH range, pH 212 and pH 213 are designed for those users that require added accuracy.

pH 213 also measures mV range when used with ORP electrodes. The large horizontal display shows both pH ( or mV) and temperature. All pH measurements are automatically compensated for the effects of 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.

These meters are equipped with a stability indicator and support proper calibration and accurate measurements. Store readings and recall them 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 electrode, stainless steel temperature probe, electrode holder, 12 Vdc power adapter and calibration buffers.

Both meters are also supplied with an opto-isolated RS232 port for PC connection.
