Metrix+ MT 18 Infrared Thermometer 200C to 1850C 80:1 Pyrometer

A. Product Overview

The Metrix Plus MT 18 Infrared Thermometer is an industrial high temperature pyrometer designed for fast and safe non contact surface temperature measurement.

It offers a wide temperature measuring range of 200°C to 1850°C, making it particularly useful for applications where conventional contact temperature sensors may be difficult, unsafe or impractical to use.

The MT 18 features an 80:1 distance to spot ratio, allowing operators to measure relatively small targets from longer distances. This is valuable when checking extremely hot equipment such as furnaces, kilns, heated metals and industrial machinery.

The instrument also provides adjustable emissivity from 0.10 to 1.00, allowing it to be configured for different surface materials.

B. Working Principle

The Metrix Plus MT 18 Infrared Thermometer measures temperature by detecting infrared radiation emitted from the surface of an object.

Every object with a temperature above absolute zero naturally emits infrared energy. The amount of infrared radiation changes according to the temperature and characteristics of the surface.

When the MT 18 is pointed toward a target, its optical system collects infrared radiation from the selected surface. The radiation is focused onto an internal infrared sensing element.

The sensor converts the received infrared energy into an electrical signal. The instrument then processes this signal and calculates the corresponding surface temperature, which is displayed on the digital screen.

Because there is no requirement for physical contact between the thermometer and the object, extremely hot or difficult to reach surfaces can be measured safely.

The 80:1 distance to spot ratio is particularly important for industrial applications. It allows the instrument to measure a comparatively small target even when the operator is positioned farther away.

Adjustable emissivity also helps improve measurement accuracy when checking different materials and surface conditions.

C. Why Is the Metrix Plus MT 18 Used?

The Metrix Plus MT 18 is used when temperature needs to be measured quickly without physically touching the surface.

It is particularly useful for high temperature industrial applications where inserting a contact sensor may be unsafe, difficult or inconvenient.

Common reasons for using the MT 18 include:

High Temperature Measurement

The measuring capability up to 1850°C makes it suitable for extremely hot industrial processes.

Safer Temperature Checking

Operators can measure hot surfaces from a distance instead of approaching extremely hot machinery or processes.

Faster Measurements

The approximately 500 ms response time allows quick temperature checks during inspection and maintenance.

Measurement From Longer Distances

The 80:1 optical ratio helps technicians measure smaller targets from a comparatively greater distance.

Preventive Maintenance

Regular temperature monitoring can help identify overheating motors, bearings, electrical equipment and machinery before serious failure occurs.

Process Monitoring

Operators can quickly verify whether industrial equipment and processes are operating within the expected temperature range.

Non Contact Measurement

There is no requirement to place a probe directly on the hot surface.
