PCE-555
hydrometer
handheld,
pocket-sized hydrometer, measures humidity,
temperature,
dew point and wet bulb globe
temperature
|
|
This
hydrometer has been developed to take quicker
measurements of humidity and temperature. The PCE-555
hydrometer also offers a calculation of dew point and
information about
wet bulb globe temperature.
This allows for the elimination of fungus in food
storage, as well as in food transportation. It is also
very useful in the construction industry for determine
condensation in walls.
Thanks to its solid design, this hydrometer is ideal for
taking measurements in situ, so long as the humidity
sensor is not touched, not manipulated or not placed
directly into liquid as it is a very sensitive component.
This
table
perfectly illustrates the relationship that exists
between dry bulb temperature, wet bulb temperature and
relative humidity.
This

shows another hydrometer, which is superior to this
model, with the ability to recalibrate it with two humidity standards.
Here you will find an overview of all our
hydrometers.

|
 |
 |
|
With the PCE-555
hydrometer you can measure ambient
conditions including humidity in the top
portion of the LCD and temperature shown on
the bottom and also calculates wet bulb
temperature and dew point, which are useful
for calculating thermal stress. There is a
small video to the right which shows the
device measuring humidity and temperature.
This
link
shows another hydrometer which can measure
relative humidity, temperature, calculate
dew point and has memory for storing
readings. We also have another type of
hydrometer which can measure relative
humidity, temperature, calculate dew point
and also measure absolute humidity with a
sensor. |

Dry bulb temperature is simply the environmental
temperature. It's the temperature that is
measured using any kind of thermometer.
Wet bulb temperature is determined by using a
mercury thermometer which is situated in the
shade with the bulb covered with a piece of wet
fabric under a current of air, measuring, for
example, a vent or a rotating electric fan. In
this way, the evaporation of water absorbs heat
lowering the temperature, reflecting the
decrease in the temperature reading. The lower
relative humidity is, the quicker the water in
the fabric will evaporate and the further the
resulting decrease with respect to the dry bulb
temperature. (this is used to give an idea of
thermal sensation)
Dew point is the temperature at which air vapour
turns into condensation, producing dew or mist,
or if the temperature is low enough, frost.
