FUNCTIONS/APPLICATIONS

Infrared thermometer Maxwell 3 CONDTROL is designed for 

non-contact measurement of object surface temperature. 

Ergonomic, shock-resistant housing, small size and weight, 

intuitive interface, laser pointer, scanning mode provide ease 

and convenience of temperature measurement of dangerous, 

moving, hard-to-reach distant objects in less than one second 

at short press of the trigger.

The principle of operation of infrared thermometer is based 

on measuring the intensity of infrared radiation of the object 

surface.

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 

different surfaces but

equal temperature emit different 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 

Low

 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 serve as the reference to determine the size and 

position of measured spot.

1500       1000       500     -  distance (D)
