B. Working Principle

The Metrix Plus MT 12A Infrared Thermometer works on the principle of infrared radiation measurement.

Every object emits infrared energy according to its temperature. The amount of infrared radiation emitted increases and changes as the surface temperature changes.

When the MT 12A is pointed toward an object, its focusing lens collects the infrared energy naturally emitted by the target surface.

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

The instrument then processes this signal and calculates the corresponding surface temperature. The measured temperature is displayed on the backlit digital screen.

Since this process does not require physical contact with the target, temperature can be measured quickly and safely from a distance.

How the 50:1 Distance to Spot Ratio Works

The MT 12A has a 50:1 distance to spot ratio.

This means that if the thermometer is positioned approximately 50 units away from a target, the measurement spot is approximately 1 unit in diameter.

For example:

At approximately 50 cm distance, the measurement spot is approximately 1 cm.

At approximately 100 cm distance, the measurement spot is approximately 2 cm.

For better measurement results, the target surface should be larger than the measurement spot.

Why Adjustable Emissivity Is Important

Different materials emit infrared radiation at different rates.

The MT 12A allows emissivity to be adjusted from 0.10 to 1.00, helping the user adapt the thermometer according to the surface being measured.

Correct emissivity settings are particularly important when measuring different industrial materials and surfaces.

C. Why Is the Metrix Plus MT 12A Used?

The Metrix Plus MT 12A is used when quick surface temperature measurement is required without physically touching the object.

High Temperature Measurement

With a maximum measuring temperature of 1150°C, the MT 12A can be used for many industrial processes involving elevated temperatures.

Non Contact Measurement

The thermometer does not need to touch the target. This makes it useful for surfaces that are hot, moving or difficult to access.

Safer Temperature Inspection

Technicians can inspect hot equipment from a greater distance, reducing the need to approach the target closely.

Electrical Preventive Maintenance

The MT 12A can be used to identify unusual temperature increases in electrical panels and equipment during maintenance inspections.

Motor Monitoring

Maintenance engineers can check motor surface temperatures and compare readings during routine inspections.

HVAC Diagnostics

The thermometer can be used for temperature checking and troubleshooting in heating, ventilation and air conditioning applications.

Industrial Process Checks

Production and maintenance teams can quickly check surface temperatures during industrial processes.

Fast Troubleshooting

The 500 millisecond response time allows technicians to obtain readings quickly when checking multiple components or areas.

Temperature Comparison

Maximum, minimum, average and difference measurement functions help users compare temperatures during inspection and troubleshooting.
