3 Express COUNTER MAT
Place the colorimeter on the left side of the counter mat, then place both
racks on the mat. Insert the UDVs (Unit Dose Vials) for each test factor into
the corresponding row.
NOTE: The timing sequence for Unit Dose Vials color development on the
counter mats is very important. Note that the test for free chlorine should be
read immediately.
UNIT DOSE VIALS (UDVS)
Each box contains 100 UDVs (20 pouches of 5 each) for one specific
1.
test factor. Remove one pouch from each box for tests to be conducted
over the next 24 hours.
Avoid opening more pouches than you need for one day. Some UDVs
2.
have a limited shelf life and should not be exposed to the humidity in
the air more than necessary. A foil storage bag with a desiccant packet
is included that can extend the shelf life to several days.
Open pouches by tearing them, or cutting them with scissors,
3.
horizontally across the top, then remove the group of 5 UDVs.
Place each set of individual UDVs in the rack directly behind their
4.
respective test factor as noted on the counter mat.
