Preparation of buffer solution
1. FilI a clean beaker with 20 ml deionized/
distilled water.
2. Add one buffer tablet of the required pH-
value and shake or crush with a clean
stirring rod until the tablet disintegrates.
3. Allow to stand for about two minutes
to ensure that the buffer is completely
dissolved and to allow any insoluble
particles to settle.
4. Immerse the electrode into the beaker
and calibrate the SD 50 in accordance
with this instruction manual.
5. Remove the electrode and rinse it
thoroughly.
6. Use the buffer solution only once.
Note
It is important to rinse the
electrode before immersing
it in a buffer solution of a
different value.
Accuracy
Fresh buffer solutions should
always be made up in
deionized/distilled water. The
maximum tolerance based
on the pH values 4, 7 and 10
is ±0.05 pH.
Warranty
The waterproof SD50 is
guaranteed to be free from
manufacturing defects for 2
years and electrode (probe)
module for 6 months.
