Salt Package Calibration
Certificates
Vaisala's ready-dosed salt packages are delivered with
calibration certificates given on the basis of a batch check.
In other words, a sample of packages are taken from a batch
and salts are prepared according to the instructions given in
this manual. These salt solutions are then checked at Vaisala
Oy's Measurement Standards Laboratory (this calibration
laboratory is accredited by FINAS, a member of the
European Cooperation for Accreditation of Laboratories).
The calibration certificate certifies that the equilibrium
humidities generated by these salt solutions correspond to
Greenspan's calibration table within the specified accuracy
(see Chapter 7 Technical Data on page 35).
