Precise temperature control plays a central role in many industries – from industrial maintenance to food inspection. A pyrometer – also known as an IR thermometer or infrared temperature meter – lets you measure temperatures without contact, safely and within seconds. These tools are indispensable especially in hard-to-reach or hot areas.
Thanks to modern infrared technology, IR temperatures can be recorded efficiently – in industry, electrical engineering, research, building diagnostics or at home.
Every object with a temperature above absolute zero emits infrared energy. The working principle of a pyrometer is based on detecting this radiation and converting it into a temperature value. This enables IR temperature measurement without contact – ideal for hot, moving or dangerous surfaces.
Measuring the IR temperature is instant and highly accurate, without damaging or touching the object – a decisive advantage over conventional methods.
From compact IR thermometers for the home to professional pyrometers for industrial applications – the choice is large. While simple models are used to check heating, cooking temperatures or air conditioners, professional tools offer advanced functions and extreme temperature ranges.
In this category you will find Maxwell 3 and Maxwell 4. Compare the temperature range and measuring functions on the product pages. Maxwell 4 adds ambient air measurements to surface temperature measurement. Check current availability for each model.
A handheld pyrometer measures surface temperatures. It is no substitute for a thermal imaging camera for an area-wide temperature image, nor for material moisture measurement. For industrial process measurement, the tool must suit the material, temperature range and measuring set-up.
Before you buy an IR thermometer or buy a pyrometer, consider the following criteria:
These features are decisive in finding the right infrared temperature meter for your requirements.
An IR thermometers or A pyrometer is a smart investment – for precise, safe and non-contact temperature measurement in almost any application. Setting the correct emissivity is particularly important for reliable results.

A pyrometer measures surface temperature without contact via infrared radiation. It does not measure the temperature inside a component; the laser is used for aiming.
Material and surface finish affect infrared measurement. Set the emissivity according to the surface and the manual. Glossy or reflective surfaces require particular care.
The greater the distance, the larger the measuring spot. The surface being checked must cover the measuring spot sufficiently; note the ratio of measuring distance to spot diameter in the data sheet.
