Please make sure that you read these instructions carefully in order to avoid injury when using
the tool. Follow all health and safety rules and regulations. If in doubt and available please
contact a more knowledgeable source.
The product is marked with a sticker to show the laser aperture. Please make sure you are
aware of where this is before beginning.
• Maintain tool in good and clean condition for best and safest performance.
• Keep the work area clean, uncluttered and ensure there is adequate lighting.
• Maintain correct balance and footing. Ensure the floor is not slippery and wear
non-slip shoes.
• Keep children and unauthorised persons away from the work area.
• If the thermometer is damaged do not use.
• Do not point the laser directly at eyes or indirectly off reflective surfaces.
• Do not use the thermometer in the environment of explosive gas, steam or dust.
To avoid damaging the thermometer or the target please protect from the
following situations.
• Do not leave the thermometer on or near objects of high temperature.
• EMF (electro-magnetic fields) from arc welders, induction heaters.
• Thermal shock (caused by large abrupt ambient temperature changes. Allow
30 minutes for the thermometer to stabilise before use).
Safe use
The BlueSpot Infrared Thermometer is used for measuring the temperature of the objects surface,
which is applicable for various hot, hazardous or hard to reach objects. The thermometer consists
of optics, temperature sensor signal amplifier, processing circuit and an LCD display.The optics
collect the infrared energy emitted by an object and focus onto the sensor.The sensor then
translates the energy into an electricity signal.The signal will be shown digitally on the LCD.
The infrared thermometer boasts single dot laser targeting as well as a back light to illuminate
the screen in dark conditions.The readings are available in both Celsius and Fahrenheit. For more
accurate readings the thermometer features a hold function. Ideal for industrial and home use.

Distance to Spot Size
Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in
the thermometer). Inaccurate readings will result from measuring shiny or polished metal
surfaces.To compensate, cover the target surface with masking tape or flat black paint.
Measure the tape or painted surface when the tape or painted reach the same temperature as
the material underneath.
Emissivity
1. Open the battery compartment and insert 2 x 1.5V
AAA batteries.
2. Pull the trigger to turn on the thermometer.
3. Aim the thermometer at the target surface and pull
the trigger.The temperature will then be shown on the
LCD screen.The thermometer is equipped with a laser,
which should only be used for aiming.
How to Use the Infrared Thermometer
• When taking the measurement pay attention to the distance to spot size. As the distance
(D) from the target surface increases the spot size (S) of the area measured becomes
larger.The distance to spot size of the thermometer is 12:1.
The thermometer is equipped with a laser which you use for aiming.
• Field of view: Make sure the target is larger than the laser spot size.The smaller the target
the closer measure distance should be. When accuracy is critical, make sure the target is at
least twice as large as the spot size.

To find a hot spot, aim the thermometer outside of
interest and then scan across with an up and down
motion until you locate the hotspot.
