standards in scientific applications. In the test
chamb er of the cell, a saturated salt solution is
created with a defined level of relative humidity.

both laid down or overhead mounted positions.
The complete humidity range of 11 % to 97 % rH is
covered through different models, which differ in
salt content. For checking purposes, at least one
cell is required. For adjustment of sensors, at least
two different cells (e.g. 11% rH and 75 % rH)
should be used. Complete sets are available for

With proper usage, the reference cells can be used
for over many years. If there is change in liquid
level, the cells can be returned to our customer
service department for regeneration or re-filling.
For each service order, you can get a test report
with record of accuracy. Further information on
handling is enclosed with the cells.
The cells are available in two physical shapes with
nine different salt fillings each. The salts used are
of most pure laboratory grade. An overview of the
delivery program is available on our homepage.
Besides the standard models, unfilled membrane
containers as well as special designs are also
available. For further information, please contact
