ETI 8000 Operating Instructions

BUFFER SOLUTIONS/CAPSULES
It is recommended that you use buffer solutions closest to
your expected measurement range. If you are measuring
approx. 5 pH then calibrate using 7.00 & 4.01 pH buffer
solutions.
Rinse the pH & temperature probes in de-ionised water
before placing in each buffer solution, if this is not
available tap water is acceptable. The buffer solution's
value changes with temperature and so the instrument
automatically compensates for this during calibration.
Therefore only buffer solutions that follow the temperature
coefficients shown in the table below should be used with
these instruments for best accuracy.
