MOLD DETECTOR
Infrared Thermometer with dew point
6. Getting started
• Open the battery compartment. The battery compartment is located inside of the handle.
Flip the battery compartment cover down.
• Connect the battery 9 V, polarity as indicated.
• Insert the battery into the battery compartment. Please pay attention to the connection
wires.
• Close the battery compartment again. The cover is properly inserted in the housing, as
soon as a click is heard.
• The device is ready for use.
7. Measuring procedure
• Press the red measuring button on the handle to activate the device. A click is heard.
• You can activate/deactivate the backlight and the laser by pressing the laser/backlight
button. With each press of the button the status changes as follows:
• Laser on/backlight off
• Laser on/backlight on
• Laser off/backlight on
• Laser off/backlight off
• appears on the display when the laser is activated.
• The measuring surface is in the middle between the two laser points.
• The surface temperature of the measuring surface is displayed in the lower part of the
display.
• The measured value of the thermo-hygro sensor is displayed in the upper part of the dis-
play.
• Each press on the MODE button in normal mode will change the display between:
• Ambient humidity (%RH)
• Dew point temperature (DP)
• Ambient temperature (AT)
• The LED lights (green/yellow/red) indicate the dew point status:
• Green light: no mould hazard
• Yellow light: Increased danger of mold, an intermittent alarm will sound
• Red light: Imminent danger of mold, a continuous alarm will sound
• There is a bar graph display located on the right side of the display. The more bars are
displayed, the higher the risk of mold.
• Press the °C/°F button, to change between °C (default) or °F as temperature unit.
• Press the red measuring button on the handle to deactivate the device.
• When the instrument is not used, it will automatically switch off after 15 minutes.
8. Distance, Spot Size, and Field of View
• As the distance (D) from the object increases, the spot size (S) of the area measured by
the device becomes larger at a ratio D:S = 12:1 (e.g. 120 cm distance = 10 cm spot size).
To get the most accurate temperature reading, aim at the target as near as possible.
• Should the distance be too great, there is a risk the temperature outside the aimed target
has also been taken. The double laser helps to aim the measuring spot exactly.
Please take note of the following:
• Not suitable for measuring shiny or polished metal surfaces (stainless steel, aluminium,
etc.).
• The device cannot measure through transparent surfaces such as glass or plastic. It will
measure the surface temperature of the glass instead.
9. Care and maintenance
• The sensor is the most delicate part of the infrared thermometer. Please protect the sen-
sor part from dirt.

11. Waste disposal
This product and its packaging have been manufactured using high-grade materials and compo-
nents which can be recycled and reused. This reduces waste and protects the environment.
Dispose of the packaging in an environmentally friendly manner using the collection systems
that have been set up.
Disposal of the electrical device
Remove non-permanently installed batteries and rechargeable batteries from the
device and dispose of them separately.
This product is labelled in accordance with the EU Waste Electrical and Electron-
ic Equipment Directive (WEEE).
This product must not be disposed of in ordinary household waste. As a con-
sumer, you are required to take end-of-life devices to a designated collection
point for the disposal of electrical and electronic equipment, in order to ensure
environmentally-compatible disposal. The return service is free of charge.
Observe the current regulations in place!
Disposal of the batteries
Batteries and rechargeable batteries must never be disposed of with household
waste. They contain pollutants such as heavy metals, which can be harmful to
the environment and human health if disposed of improperly, and valuable raw
materials such as iron, zinc, manganese or nickel that can be recovered from
waste. As a consumer, you are legally obliged to hand in used batteries and
rechargeable batteries for environmentally friendly disposal at retailers or appro-
priate collection points in accordance with national or local regulations. The
return service is free of charge. You can obtain addresses of suitable collection
points from your city council or local authority.
The names for the heavy metals contained are:
Cd=cadmium, Hg=mercury, Pb=lead.
Reduce the generation of waste from batteries by using batteries with a longer
lifespan or suitable rechargeable batteries. Avoid littering the environment and
do not leave batteries or battery-containing electrical and electronic devices lying
around carelessly. The separate collection and recycling of batteries and
rechargeable batteries make an important contribution to relieving the impact on
the environment and avoiding health risks.
