Technical FAQ:
Portable optical pyrometers
What is a portable optical pyrometer?
It is a battery-powered non-contact temperature measuring instrument equipped with an advanced optical system (visual viewfinder, telescopic eyepiece, interchangeable optics, or two-color technology). It combines the portability typical of handheld pyrometers with the aiming precision of laboratory optical systems.
What is a portable optical pyrometer used for?
It is used to perform high-precision temperature measurements on specific objects, even at great distances, while on the move: inspection of furnaces and hightemperature systems, quality control in metallurgy, R&D measurements in the laboratory, inspection checks in iron and steel, glass, and ceramics industries.
In which sectors are portable optical pyrometers used?
They are used in metallurgy (checks on furnaces, rolling mills, foundries), glass industry (melting and forming furnaces), ceramics, cement, research and development, university laboratories, verification of high-temperature process systems, quality control on incandescent products.
What is the difference between a portable optical pyrometer and a portable laser pyrometer?
The portable laser pyrometer uses the laser as a pointing aid but has standard optics, optimized for general maintenance use. The portable optical pyrometer integrates a visual viewfinder (optical eyepiece with reticle) that allows the operator to see exactly the measurement area, fundamental for precision applications and at long distances.
What is a telescopic viewfinder in a portable optical pyrometer?
It is an optical system similar to a telephoto lens, with variable magnification (typically 2x–10x) and internal reticle highlighting the actual measurement area. It allows the operator to precisely aim at objects tens of meters away or of small dimensions,
providing a sharp view of the target.
When is a portable two-color pyrometer useful?
It is useful when the target is partially covered by smoke, dust, or vapor; has uncertain or variable emissivity (metals, colored ceramics); or is smaller than the nominal measurement area. The two-color pyrometer calculates the ratio between two wavelengths, eliminating these errors and ensuring stable measurements even in difficult conditions.
What temperature ranges do portable optical pyrometers cover?
They typically cover from +200 °C up to 3000 °C, with specialized models reaching 3500 °C for molten metals, plasma arcs, and advanced applications. For low ranges (below 200 °C), LWIR portable laser pyrometers are preferred, being more economical and versatile.
What interchangeable optics are available for portable optical pyrometers?
Standard optics for distances 0.3–3 m, telephoto for distances 3–30 m, macro for objects of a few millimeters, short focal for laboratory applications. Optics are quickly replaceable without additional calibration, since the IR sensor remains the same.
Do portable optical pyrometers have datalogging functions?
Yes, professional models integrate internal memory for up to thousands of readings with timestamps, downloadable via USB or Bluetooth to dedicated software. Some models also record the optical image of the target at the time of measurement, useful for documentation of audits and inspection reports.
How is emissivity correctly set?
Emissivity is set by selecting the material from the integrated database or by manually entering the value (0.01–1.00 with 0.01 resolution). For unknown or variable materials, it is preferable to use a two-color model, less sensitive to emissivity setting errors.
What is the battery life of portable optical pyrometers?
Typical battery life is 10–20 hours with rechargeable lithium batteries or standard alkaline batteries, sufficient for entire days of inspection. Models with illuminated viewfinder and continuous datalogging have slightly reduced battery life.
How accurate are portable optical pyrometers?
Typical accuracy is ±0.5% of the reading + 1 °C, with better repeatability (±0.1%). Premium metrology models achieve ±0.3%. Annual periodic calibration with a reference blackbody and ISO/IEC 17025 certificate ensures the maintenance of declared performance.
