With a resolution selectable between 0.01 and 0.001 over the -2 to 16 pH range, the top-of-the-range PHB-212 and PHB-213 are designed for those users that need added accuracy. Both meters are supplied with opto-isolated RS232. The pH and temperature are displayed simultaneously and all pH measurements are automatically compensated for the temperature variance. With the probe detached, temperature can also be manually compensated for. PHB-213 also measures mV in the ±999.9 mV range when used with ISE’s and ORP electrodes. The large horizontal display shows both pH (or mV) and temperature at the same time. Calibration comes with prompts for the operator, thanks to the meter’s sophisticated custom microprocessor. 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 hi-tech stability indicator ensures a proper calibration is carried out and that all subsequent measurements are accurate. A particular measurement can be memorized and recalled at a later time at will. The front label carries clear and concise information about how to operate the meters.
