Metrix+ MT 16 Infrared Thermometer -18C to 1650C 50:1 Pyrometer

A. Product Overview

The Metrix Plus MT 16 Infrared Thermometer is an industrial handheld pyrometer designed to measure surface temperatures without physically touching the target.

It provides a wide temperature measuring range of minus 18°C to 1650°C, making it suitable for both general industrial maintenance and high temperature processes.

The instrument features a 50:1 distance to spot ratio, which allows technicians to measure relatively small target areas from a greater distance. This is particularly useful when the equipment being inspected is extremely hot, moving, electrically live or difficult to reach.

The MT 16 also provides adjustable emissivity from 0.10 to 1.00, allowing measurement settings to be adapted for different surface materials.

B. Working Principle

The Metrix Plus MT 16 Infrared Thermometer works by detecting infrared radiation naturally emitted from the surface of an object.

Every object above absolute zero emits infrared energy. The amount of infrared radiation produced depends mainly on the temperature and surface properties of the object.

When the MT 16 is pointed toward a target, its optical system collects the infrared radiation emitted from the selected surface. This energy is focused onto an internal thermopile sensor.

The sensor converts the infrared radiation into an electrical signal. The internal electronics then process this signal and calculate the corresponding surface temperature, which appears on the digital display.

How the 50:1 Ratio Works

The 50:1 distance to spot ratio describes the relationship between the measurement distance and the diameter of the area being measured.

For example, at approximately 50 cm distance, the measurement spot is approximately 1 cm in diameter.

This allows the user to measure smaller areas while remaining at a safer distance from hot equipment.

For reliable measurement, the target should normally be larger than the instrument's measurement spot.

Why Emissivity Matters

Different materials emit infrared radiation differently.

The MT 16 provides adjustable emissivity from 0.10 to 1.00, helping the user compensate for differences between surfaces such as painted materials, oxidized metals and other industrial surfaces.

Highly reflective or polished metallic surfaces can require special attention when taking infrared temperature measurements. 

C. Why Is the Metrix Plus MT 16 Used?

The Metrix Plus MT 16 is primarily used when temperature needs to be checked quickly without touching the object being measured.

High Temperature Measurement

Its measuring capability up to 1650°C makes it suitable for many high temperature industrial processes.

Safer Temperature Measurement

Hot machinery, furnaces, electrical components and moving equipment can be measured from a distance without bringing the instrument into direct contact with the target.

Preventive Maintenance

Maintenance personnel can use infrared temperature measurements to identify unusual heating in electrical panels, motors and machinery.

Unexpected temperature increases can be an indication that equipment requires further inspection.

Faster Inspection

The approximately 500 ms response time allows technicians to perform multiple temperature inspections quickly.

Hard to Reach Equipment

The 50:1 optical ratio is useful when the target cannot be approached easily because of heat, height, movement or physical obstructions.

Non Contact Process Monitoring

The instrument can be used to check temperature during industrial processes without attaching a probe to the product or equipment.

Frequently Asked Questions

1. What is the temperature range of the Metrix Plus MT 16?

The Metrix Plus MT 16 measures temperatures from minus 18°C to 1650°C, equivalent to approximately 0°F to 3002°F.

2. Is the Metrix Plus MT 16 a contact thermometer?

No. It is a non contact infrared thermometer that measures surface temperature by detecting infrared radiation emitted from the target.

3. What is the distance to spot ratio of the MT 16?

The instrument has a 50:1 distance to spot ratio, making it suitable for temperature measurements from comparatively greater distances.

4. What does 50:1 mean in an infrared thermometer?

A 50:1 ratio means that at a distance of approximately 50 units, the thermometer measures a spot approximately 1 unit in diameter.

For example, from approximately 50 cm away, the measurement spot is approximately 1 cm.

5. Can the MT 16 measure furnace temperature?

The MT 16 can measure surface temperatures up to 1650°C, making it suitable for many furnace related temperature inspection applications.
