When the salt has dis-
solved completely, add all
the content of the second
bottle of HI 7111.
•
Allow the solution obtained
to cool, and then pour it
into the chamber marked
"RH 11.1%", making sure
that no residue remains on
the walls of the glass con-
tainer.
•
Seal the chamber well when not in use,
as the LiCl solution is extremely hygro-
scopic and tends to capture the humidity
present in the air causing the solution to
expand in volume and to overflow from
the container.
•
Pour approximately 12 cc
of distilled water into the
other chamber marked
"RH 75.4%".
•
Add all the content of the
HI 7121 bottle containing
NaCl while continuously
shaking the container to
avoid the formation of
lumps. Seal this container
well when not in use.
•
The calibration kit needs
approximately 4 hours for
stabilization.
