recommended to use silicone oil supplied with the instrument.
3) Mix and Degassing
Samples should not be violently shaken or agitated. It is recommended to slowly roll
over sample vial to make solution evenly; Air bubble in solution will cause big error to
turbidity measurement. So air bubble must be eliminated before measuring. But
obviously mix and degassing is a process of contradiction, especially for solution with
precipitate, it's much more difficult to handle. Need some operating experience or
stipulate some measurement condition. For example, stipulate same mix condition and
stewing time for degassing, then compare measuring value.
4) Other Requirements
a) On the premise of ensuring uniform sample, sample should be measured immediately
to prevent temperature changing and precipitate from effecting measuring value.
b) As far as possible to avoid the sample dilution for measurement.
c) Avoid operating under direct sunlight.
d) Don't pour solution into measuring well, sample vial must be used for measurement.
e) Please don't try to wash measuring well, this may damage the optical structure of
measuring well.
