Compact thermometer -
hygrometer with optional external
temperature probe
This model is designed to measure temperature,
relative humidity and dew-point temperature by internal
sensor, moreover one additional external temperature
probe Pt1000/E can be connected. Internal sensors
are located under the grid on the front of the device.
The device also measures the temperature
from an external probe and the difference between
this temperature
and the dew point temperature.
If the surface temperature of the material is measured
by an external probe, the risk of condensation of water
vapor on the surface to be measured can be determined
immediately.
The device alone is suitable for measuring
in places where there is no rapid change in temperature
or relative humidity, and there is no condensation
of water vapours. If water vapour condensation occurs
inside the datalogger, then the resulting water
will remain there and may damage its electronics.
The device is placed directly in the measured area,
while the installation needs to ensure sufficient level
of GSM signal at the installation location. As the internal
battery creates a parasitic heat during the charging
period, the measurement accuracy may be affected by up
to 1 º C.
We recommend calibrating the relative humidity
and temperature of this device in the laboratory
with a sufficient air flow (at least 1 m / s), the reading can
be performed only after thorough settling, which can take
up to 4 hours.
The maximum length of each probe lead should not
exceed 15 m. It is recommended to use shielded cables.
To maintain the IP rating, the unused probe connector
should be provided with a supplied closing cap.
