Vaisala Humidity Calibrator HMK15 for multi-point on-site calibrations.
Humidity Instrument
Calibration
In calibration, the humidity reading
of an instrument is compared against
a portable reference. The reference
should be regularly calibrated and
provided with a valid certificate.
When selecting one of the many
calibration methods, time, cost,
technical requirements, expertise,
and the unique needs of the
organization must be balanced.
Portable meters and products that
can be removed from the installation
can be calibrated in an approved
laboratory or returned to the
instrument provider for calibration.
Vaisala has four Service Centers
around the world available for
calibration.
Instruments installed in processes
that operate within narrow
boundaries can be calibrated using
on-site one-point calibration that can
be performed without disconnecting
the instrument. One-point calibration
can also be used to identify the
need for further calibration and
adjustment.
Some portables such as the Vaisala
HUMICAP
®
Hand-Held Humidity
and Temperature Meter HM70 or
the Vaisala DRYCAP
®
Hand-Held
Dewpoint Meter DM70 can be directly
connected to the installed product
and the readings compared to those
on the portable meter’s display.
In environments with large
variations in humidity, multi-point
calibration is recommended. Two-
point or three-point calibrations
can be accomplished in the
field with the help of humidity-
generating equipment, as long as
the local environment is at a stable
temperature. The advantage of multi-
point calibration compared to one-
point calibration is higher accuracy
over the entire measurement range.
Multiple humidity levels can be
created with the Vaisala Humidity
Calibrator HMK15, for example.
Calibration of Dew Point
Instruments
It is a demanding task to perform
high-quality calibrations on low
dew point instruments. For this
reason, Vaisala doesn't recommend
customers perform calibrations
on Vaisala DRYCAP
®
products.
Instead, they should be calibrated in
professional calibration laboratories,
such as Vaisala Service Centers.
However, it is possible to perform a
field check on a dew point instrument
to identify whether adjustment is
needed, using the Vaisala DRYCAP
®
Hand-Held Dewpoint Meter DM70.
