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 
temperature probe detached, manual temperature compensation 
is possible. PHB-213 also measures mV in the ±999.9 mV range 
when used with ISEs 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 4.00, 6.86, 7.00, 9.18 and 10.00. 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.
