Hygrometers
|
|
In our
web pages, you will find hygrometers that can
measure relative air humidity, or combine d devices that
can also measure temperature. These hygrometers
measure different ranges of humidity depending
on the
model. Relative air humidity is an important factor in
most sectors, including industrial, transport and
gardening. They are versatile in that they can take
measurements, store them to memory and transfer data to
a computer for further detailed analysis. There is also
the calibration standards for the device which makes it
easy to ensure that measurements are their most accurate.
Many of our hygrometers come with an ISO
calibration certificate and some models are legally
validated. They are very useful in evaluating damage in
a warehouse. If you don't find the hygrometers
you are looking for, please contact us and we will help
you find the best solution to suit your needs by calling

All hygrometers come calibrated, but as their
sensor's accuracy deteriorates with use, they should be
recalibrated on a regular basis. A calibration can be done
by the user of the device by using that optional calibration
standards or the device can be sent to us and we will
perform a recalibration that will meet ISO standards. (Calibration
/ recalibration of hygrometers).

Information
about relative humidity: Relative humidity (r.h.)
shows the relationship between absolute humidity (the amount
really there) and the saturation state of water vapors. Relative
air humidity is measured using hygrometers, that
show on their displays from 0% (absolutely dry air) up to 100%
(air that is completely saturated, such as fog, clouds or steam
bath). Some models of hygrometers have an unlimited measurement
range. The physical area is between 40 and 65% r.h. Given that
hot air possesses the ability to absorb more water vapour than
cold air, people feel that in winter, air is too dry and in
summer it is too humid. If air heats up it increases the amount
of water vapour to that of saturation. The consequence is that
the % of relative humidity decreases while the real quantity of
water remains constant. Something similar occurs when air is
cooled, decreasing the quantity of water vapour. This increases
the percentage value of relative humidity. Condensation forms
when there is an excess of water in saturated conditions. Some
of our hygrometers offer the ability to not only measure
relative humidity and temperature, but can also calculate dew
point and dew point temperature. Dew point temperature is
defined as the temperature at which the actual vapour content of
air is the maximum (100% relative humidity). Dew point
temperature is independent of the actual temperature. One
possibility of dew point temperature is freezing metal until its
surface forms condensation. The temperature of the metal will
then be the dew point temperature. As we have mentioned, many of
our hygrometers show dew point on their display. |
