HI 7101 and HI 7102 portable
chambers allows you the capability
of calibrating your hygrometers. The
kits are composed of two thermally
isolated chambers, each one
equipped with a cap and three
bottles containing the appropriate precalibrated saturated
salts to produce a known RH value: two 15-gram bottles of
Lithium Chloride (LiCl) and one 33-gram bottle of Sodium
Chloride (NaCl).
HI 7101 is used with HI 8564, HI 9064, HI 9065,
HI 9161, HI 9261 and HI 91610 (HI7101).
HI 7102 is used with HI 93640 and HI 8666.
They measure only 190x115x110 mm.
You can check the status of your probe and perform a quick
recalibration (with an accuracy of ±5%) by using the
Hanna mini-calibration chambers HI 7101 and HI 7102.

OLUTIONS
:
• Pour approximately 26 cc of distilled
water into a glass container.
• Immerse this container into a bath of ice
and water and shake briefly.
• Slowly add the contents of a HI 7111
bottle containing LiCl into the glass con-
tainer while continuing to shake.
tainer while continuing to shake.
• When the salt has dissolved 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
"RH11.1%", making sure that no resi-
due remains on the walls of the glass
container.
"RH11.1%", making sure that no resi-
due remains on the walls of the glass
container.
• Seal the chamber well when not in use, as the LiCl
solution is extremely hygroscopic and tends to capture
the humidity present in the air causing the solution to
expand in volume and to overflow from the container.
