A pyrometer is a highly specialised instrument for non-contact temperature measurement used in a range of industries. Pyrometers are known for their precision in measuring temperature. They measure temperature by detecting the IR emitted from an object to determine its temperature.
A pyrometer is an optical device that measures IR detection. Every object with a temperature above absolute zero emits IR. The amount of radiation an object emits depends on its temperature. A pyrometer captures this radiation, analyses it and determines the object’s temperature without needing to touch it. This temperature measurement method ensures readings are precise and can be measured in a vast range of materials and environments.
Pyrometers stand out due to their non-contact approach to temperature measurement. The pyrometer calculates the object’s precise temperature by capturing the IR emitted by an object and analysing its intensity and wavelength. This method is especially beneficial for objects that are extremely hot or in motion, ensuring accurate readings without direct contact.
Learn more about the advantages of pyrometers over contact thermometers.
Pyrometers have become an indispensable sensor in a wide range of industrial applications. Their unique non-contact temperature measurement capabilities make them ideal for measuring extremely hot or potentially hazardous objects. Pyrometers can be used to measure the temperature of almost any object, including molten metals and moving machinery. They are known for accurate and consistent readings, making them a trusted choice in many industries.
There are five main types of pyrometers. These are:
Single-Colour Pyrometers
Single-colour or single-wavelength pyrometers measure the IR radiation emitted by an object at only one wavelength. Models covering different spectral ranges or wavelengths need to be selected according to the material being measured and the required temperature range. A single-colour pyrometer will provide excellent measurement accuracy when selected correctly for given applications.
Dual-Colour Pyrometers
A dual-colour pyrometer, also known as a dual-wavelength or ratio pyrometer, uses two single-colour pyrometers to simultaneously measure an object’s temperature across two different wavelengths. This makes the measurement independent of factors that affect the signal intensity, such as contaminants in the air between the object and the pyrometer, including dust, steam or smoke. For some applications, the pyrometer is unaffected by emissivity changes as there is a neutral change in both measuring channels.
Fiber Optic Pyrometers
A fiber optic pyrometer is one in which the optics and electronics are separate but connected using a fiber optic cable. The IR radiation is collected by the optics and guided to the detector via a flexible fiber optic cable. As the receiving optics do not contain any electronics, it is a more compact size and ability to withstand higher ambient temperatures.
Transfer-Standard Pyrometers (TSP)
TSPs are the most accurate type of pyrometer and are used to calibrate other pyrometers. They do this by taking the reference temperature from a blackbody and transferring this reference to another pyrometer that needs their measurement verified.
Impac® IS 12-TSP and IGA 12-TSP
Portable Pyrometers
A portable or handheld pyrometer can easily be moved from one location to another for quick spot temperature measurements. The main advantage is that, for a modest investment, a single pyrometer can take accurate temperature measurements at multiple locations around the plant.
Explore the different types of pyrometers in our comprehensive guide.
A pyrometer is a type of thermometer; however, it measures the temperature of an object without contact. A pyrometer measures the amount of IR emitted by an object and uses this information to determine the object’s temperature. Your choice of temperature measurement device will depend on your intended application.
Accurate non-contact measurement is essential in all types of industries and processes. They are often used to measure hot objects such as glowing metal and molten glass, and specific models are available to suit almost all industries and applications.

When rebuilding one of our clamshell furnaces we opted for four Impac ISR 6 pyrometers for precise temperature measurement. I am very impressed with the quality of every component from the cooling jackets to the sensors themselves, which seem exceptionally well made. I would not hesitate to contact LIMAB in the future for any other applications that I may need help/equipment for.
