B. Working Principle

The Metrix Plus MT 4xL Infrared Thermometer works by detecting infrared energy naturally emitted from the surface of an object.

Every object emits infrared radiation depending on its temperature. As the surface temperature changes, the intensity of infrared radiation also changes.

When the MT 4xL is pointed toward a target, its focusing lens collects the infrared energy emitted by the surface.

This infrared radiation is directed toward an internal thermopile sensor. The sensor converts the detected infrared energy into an electrical signal.

The internal electronic circuit processes this signal and calculates the corresponding surface temperature. The result is then shown on the backlit digital display.

Since the instrument does not need to physically touch the surface, measurements can be taken quickly from hot, moving, difficult to access or sensitive objects.

How the 12:1 Distance to Spot Ratio Works

The Metrix Plus MT 4xL has a 12:1 distance to spot ratio.

This means that at a distance of approximately 12 units, the instrument measures an area approximately 1 unit in diameter.

For example:

At approximately 12 cm distance, the measurement spot is approximately 1 cm.

At approximately 60 cm distance, the measurement spot is approximately 5 cm.

For reliable measurement, the target should generally be larger than the measurement spot.

Preset Emissivity

The MT 4xL has a preset emissivity value of 0.95.

This setting is commonly suitable for many non reflective surfaces such as painted surfaces, plastics, rubber and many other materials typically encountered during maintenance and inspection work.

Highly polished or reflective metal surfaces may require additional consideration when performing infrared temperature measurements.

C. Why Is the Metrix Plus MT 4xL Used?
