Warranty
The warranty is for 12 months. Damages caused by incorrect use
by untrained people or start-up by unauthorised people are
excluded from the warranty.
The device complies with the fundamental health and safety
requirements of the applicable EU regulations and was tested at
the factory for perfect functionality multiple times. However, if
faults in the functionality occur and cannot be remedied with the
measures in the chapter Errors and faults, please get in touch
with your dealer or distributor. When making a warranty claim,
supply the device number (see the rear of the device). The invoice
acts as warranty certificate. When manufacturer's instructions or
legal regulations have not been followed, or after unauthorised
changes to the device are made, the manufacturer is not
responsible for the resulting damages. Changes to the device or
unauthorised replacement of individual parts can drastically
impact the electrical safety of this product and leads to the forfeit
of the warranty. Liability does not extend to damages to people or
property caused by the device being used other than as described
in the instructions in this operating manual. Subject to changes to
technical design and model changes as part of constant
development and product improvement without prior notice.
No liability is accepted for damages resulting from improper use.
In such cases, entitlements to a warranty are then also forfeited.

The infraredthermohygrometer comes equipped with the
functions of a thermohygrometer and a pyrometer.
The device can capture the following measured values:
• Air temperature (°C, °F),
3
• Relative (% RH) and absolute humidity (g/m
• Dew point temperature (dp °C, dp °F),
• Mixing ratio (g/kg, gr/lb),
• 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 MultiMeasure
Studio software.

By use of CAL a single-point calibration can be carried out for the
selected sensor indications. All sensors are already
factory-calibrated and have a corresponding characteristic
calibration curve. By stating a calibration value (offset) a global
shift of the calibration curve, which has an effect on the entire
measuring range, is performed for the single-point calibration!
The offset value to be entered is that value by which the
calibration curve will be shifted.
Example:
The displayed value is always 5 too high => change the offset
value for this measurement channel to -5.
The offset value's default setting is 0.0.

5. Switch the acoustic and visual signal on or off by use of

– If the bars (22) in the upper and lower measured
value display are flashing, the acoustic and visual
signal is activated.
– If the bars (23) in the upper and lower measured
value display are flashing, the acoustic and visual
signal is deactivated.
In IR DP mode the alarm function is activated automatically. Alarm
triggering and intensity are defined by the upper and lower alarm
threshold.
These two limit values can be calculated from the measured dew
point temperature (TdP) and the threshold values individually
determined in configuration mode: upper threshold (Hi) and lower
threshold (Lo).
The sum of dew point temperature (TdP) and upper threshold
value (Hi) constitutes the upper alarm limit value (TdP + Hi).
The difference of dew point temperature (TdP) and lower
threshold value (Lo) constitutes the lower alarm limit
value (TdP - Lo).
If the surface temperature falls below the upper alarm
limit (TdP + Hi) an acoustic and visual alarm (flashing laser and
flashing ALARM display) is triggered which intensifies in
proportion to the increased approximation to lower alarm limit.
The more the surface temperature drops, the faster increases the
repetition frequency of the acoustic and visual signals. Maximum
repetition frequency is triggered when reaching the lower alarm
limit (TdP - Lo).
Example: The current dew point temperature (TdP) is +10 °C.
You define the upper threshold (Hi) as 5 °C and lower
threshold (Lo) as 5 °C. Then the alarm starts at +15 °C (TdP + Hi)
and reaches maximum intensity at 5 °C (TdP - Lo).

• As soon as operating mode IR or IR DP is selected, the laser

The device can be connected to a PC via the USB interface (5).
See chapter PC software on page 12.
Switch-off
1. Press and hold the On/Off key (4) for approx. 3 seconds until
a beep is emitted.
– The device will be switched off.
2. If applicable, put the protective cap back on the infrared
sensor.
Measuring principle
The device comes with a measuring sensor for air temperature
and humidity.
It is further equipped with an infrared sensor for the measurement
of surface temperatures.
The degree of emission and the ratio of the distance to and the
size of the measuring spot play an important role when using the
infrared sensor for measurements.
Degree of emission
The degree of emission is used to describe the energy radiation
characteristics of a material.
The higher this value, the higher is the ability of the material to
radiate. Many organic materials and surfaces have a degree of
emission of approx. 0.95.
Metal surfaces or shiny materials have a lower degree of
emission and therefore only yield inaccurate measured values.
Please observe this when using the device.
In order to compensate this, the surface of shiny parts can be
covered with adhesive tape or matt black colour.
The device is unable to measure through transparent surfaces
such as glass. Instead it measures the surface temperature of the
glass.
A material's degree of emission depends on various factors such
as the material composition, its surface condition and
temperature. (In theory,) It can be between 0.1 and 1.
As a rule of thumb we can assume: When a material is rather dark
and its surface texture matt, it probably has a high degree of
emission. The brighter and smoother the surface of a material,
the lower will be its degree of emission, presumably. The higher
the degree of emission of the surface to be measured, the better
it is suited for non-contact temperature measurement by use of a
pyrometer or thermal imaging camera, since falsifying
temperature reflections become negligible. Nevertheless,
entering a degree of emission as appropriate as possible is
indispensable for a precise measurement.
In order to achieve precise measurement results the measuring
object must be larger than the device's measuring spot. The
determined temperature is the average temperature of the
measured area. The smaller the measuring object, the shorter the
distance to the device.
You can gather the precise diameter of the measuring spot from
the figure below.
For accurate measurements the measuring object should be at
least twice as large as the measuring spot.
