Description of the device
The infrared thermohygrometer comes equipped with the
functions of a thermohygrometer and a pyrometer.
The device can capture the following measured values:
• Air temperature (°C, °F),
• Relative (% RH) and absolute humidity (g/m
3
),
• Dew point temperature (dp °C, dp °F),
• Surface temperature (°C, °F).
The device features three different operating modes: TH mode, IR
mode and IR DP mode.
In TH mode the device can use the functions of a
thermyhygrometer. The device measures air temperature,
humidity and dew point temperature.
In IR mode the device can use the functions of a pyrometer. The
device measures the surface temperature of objects.
The IR DP mode serves to detect critical surfaces on which
condensation could take place due to drops below dew point. The
device simultaneously indicates the surface temperature of the
measuring object and the dew point temperature within the
measurement environment.
A minimum, maximum and average function is available for the
direct analysis of the measured data. Besides, the currently
measured value can be recorded via the hold function.
The device can be operated via a capacitive touchscreen control
panel.
When not in use, an automatic switch-off saves the battery.
The device is only intended for use inside buildings, because solar
radiation (also scattered or indirect sunlight) compromises the
measurement accuracy.
You can connect the device to a computer by using the USB cable
included in the scope of delivery. Then you can extract and
analyse your measured results with the optional SmartGraph
software.
