FUNCTIONS/APPLICATIONS

Infrared thermometer Maxwell 4 CONDTROL is designed 
to measure object ’s surface temperature by non-contact 
method. It is equipped with temperature and humidity sensors 
as well as an infrared sensor for object surface temperature 
measurement, which can detect the «cold bridges» and places 
where mildew can form. One touch on the trigger allows to 
identif y poorly insulated areas in windows or to detect leaking 
areas in external walls. 

PACKAGE

Infrared thermometer Maxwell  4 – 1pc.
Power supply (1.5V A A A) - 2 pcs.
User manual - 1 pc.

4) Emissivity

All objects emit thermal energy. The volume of radiated 
energy depends on the surface temperature
and emissivity of the object. The IR-thermometer measures 
the intensity of radiation and
uses it to calculate the temperature of the object. Objects with 
dif ferent surfaces but
equal temperature emit dif ferent amount of thermal energy. 
Most of the objects and materials, for example, painted 
metals, wood, water, leather, fabric have a high emissivity 
(0.9 and more) and emit more energy than shiny surfaces and 
unpainted metals with emissivity less than 0.6. Adjustment 
of emissivity allows the device to take it into account and to 
minimize the measurement error.

Measurements

Switch on the device. Aim the device at the object of 
measurement and press the trigger. Keep the trigger 
pressed to enter continuous measurement. Symbol of active 

measurement           will appear on the display. Measurement 
results will appear on the display in real time mode. 
If measurement result is beyond the set limit, LED indicator 

turns red, the symbol 

Hi

 or

 appears on the display. When 

the trigger is released, the device keeps the last measured 

values on the display. The symbol           appears on the display.

OPTICAL RESOLUTION

As the distance from the device to the object increases, the 
size of the measured spot on object surface increases as well. 
To determine the size of the spot (S) you need to divide the 
distance from the device to the target (D) by 12.
Laser points ser ve as the reference to determine the size and 
position of measured spot.
