System 4

High-precision, single-spot pyrometers provide exceptional flexibility across a wide range of temperatures, operating wavelengths and applications.


System 4 brings together AMETEK Land’s world-leading range of highly accurate infrared and fibre optic thermometers with our Landmark signal processors, delivering plant operators a complete temperature measurement system capability.

A flexible solution tailored to your application, System 4 brings operators numerous safety, cost and product quality benefits. Operators can choose the components suited to their process, confident that they will work together reliably without the need for recalibration or constant maintenance. With thousands of installations in industrial environments System 4 has proven its durability and accuracy over many years of operation.

With its combination of focusable optics that don't require the thermometer to be removed from its protective mounting jacket and through the lens sighting for clear, guaranteed target confirmation is assured. Optional close up lenses enable System 4 to provide accurate, drift-free measurements for targets as small as 0.45mm (0.02in).

Landmark signal processing delivers intelligent and stable process temperature measurements.

Highly accurate and offering fast response speeds, System 4 is designed for continuous quality and process monitoring, that can easily be used for process control in numerous glassindustrial processing and steel applications.

System 4’s advanced range of 38 models – single wavelength, ratio, fibre optic and fibre optic ratio versions – is fully interchangeable with four System 4 Landmark signal processors and a series of mounting options, which means there’s an ideal temperature measurement solution to fit your application.

System 4 pyrometers are rugged, precise and reliable, using through-the-lens sighting from as close as 90mm (3.5in), or flexible fibre optics for normally inaccessible areas - ensuring continuous product temperature measurements, whatever the process conditions.

Suited to applications ranging from 0 °C (50 °F) to 2600 °C (4700 °F), the versatile System 4 range offers precise, dependable options designed to handle processes in harsh conditions, including high temperature and high RF environments.

System 4 is AMETEK Land’s complete family of flexible non-contact temperature measurement solutions with an extensive choice of options.
