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.
