Pawkit

• Fill the cup no more than half-full of the sample.
Pawkit does not require a large sample size to
make its reading. As long as the bottom of the
cup is covered by the sample and that the sam-
ple is representative of the product you wish to
measure, you should be able to make accurate
readings. If the sample cup is too full, you risk
contaminating the sensor, which will lead to
inaccurate readings.
• Make sure that the rim and outside of the sam-
ple cup are clean. Wipe any excess sample
material from the rim of the cup with a clean tis-
sue. Material left on the rim or the outside of the
cup will be transferred to subsequent samples
and can affect the accuracy of your readings.
The rim of the cup forms a vapor seal with the
sensor. Therefore, any sample material left on
the cup rim may prevent this seal, and contami-
nate future samples.
• If a sample will be read at some other time, put
the sample cup’s disposable lid on the cup to
restrict water transfer. To seal the lid, place tape
or Parafilm completely around the cup/lid
junction. It is necessary to seal the cup if it will
be a long time before the measurement is made.
