Best Non-Contact Temperature Measurement Solutions for UAE Industries
By Telos Instruments · Exclusive Sensortherm Distributor (GCC) · Al Uthman Building, Deira, Dubai, UAE
Quick answer: For hot, fast-moving, or hard-to-reach industrial targets, the best non-contact temperature measurement solution is usually an industrial infrared pyrometer: a 1-color pyrometer where the target’s emissivity is known and the view is clear, a 2-color pyrometer where emissivity is uncertain or the view is dusty or smoky, a high-speed pyrometer for laser and rapid-heating processes, and a handheld pyrometer for inspection rounds. Sensortherm, a German manufacturer of digital pyrometers, offers all of these (METIS, CAPELLA, FELIS, HELIOS, DIADEM) plus scanners, PID controllers, and calibration equipment. Telos Instruments, based in Deira, Dubai, is the exclusive distributor of Sensortherm in the GCC.
This guide matches non-contact temperature solutions to the problems UAE industries actually face, and shows which Sensortherm instruments fit each one.
Why Non-Contact Measurement Matters
Contact sensors such as thermocouples and probes are excellent where you can touch the target. In many industrial settings you can’t:
- The target is too hot. Molten metal, glowing steel, glass melt, and furnace interiors can destroy contact sensors or shorten their life.
- The target moves. Rolling mills, continuous casting, conveyors, and rotating parts make contact impractical.
- Contact would affect the process. A probe can cool the target, contaminate a product, or mark a surface.
- The measurement must be fast. Laser welding, induction heating, and additive manufacturing need response times contact sensors can’t match.
- Safety and access. Some targets are dangerous or physically hard to reach.
Infrared pyrometers solve these problems by measuring the radiation a hot object emits, from a distance, without touching it.
The Main Non-Contact Options
1-Color Pyrometers
A 1-color pyrometer measures radiation in one spectral band. It gives very accurate readings on most targets provided the material’s emissivity is set correctly, the target is larger than the measuring spot, and the line of sight is clear of fumes, smoke, and dust. It is the most economical and straightforward choice when conditions are stable.
2-Color Pyrometers
A 2-color (ratio) pyrometer measures in two spectral bands simultaneously and calculates temperature from the ratio of the two signals. Because emissivity cancels out in the ratio, it handles unknown or changing emissivity, targets smaller than the measuring spot, and dirty lenses, dusty or smoky environments. For wavelength-dependent emissivity (for example some bare metals), the emissivity slope must be considered.
High-Speed Pyrometers
These respond in tens of microseconds and are used where measurement drives fast control, such as laser processing, additive manufacturing, and rapid heating.
Handheld Pyrometers
Portable instruments for maintenance rounds, spot checks, and quality audits, where a fixed installation isn’t practical.
Scanners
Scanners record temperature profiles across many points, useful for moving products and profile monitoring.
Infrared Switches
Instead of outputting a temperature, these output a switching signal when a temperature threshold is crossed, useful for simple presence and over-temperature detection.
Sensortherm’s Range for Industrial Applications
Sensortherm develops and produces its pyrometers in-house in Germany, with more than 30 years of experience in digital pyrometry, ISO 9001:2015 certification, and a 2-year warranty. All Sensortherm pyrometers use fully digital signal processing, which supports reproducible measured values and consistency from device to device.

How to Choose the Right Solution
- Define the target. Material, surface condition, and whether it is solid, molten, glowing, or a flame.
- Define the temperature range. Choose a model whose range covers your minimum and maximum with margin.
- Check the spot size against the target. The target should fill the measuring spot; otherwise the reading is affected by the background.
- Choose 1-color or 2-color. If emissivity is known and the view is clear, 1-color is simple and accurate. If emissivity is uncertain, changing, or the view is dusty or smoky, 2-color is more tolerant.
- Choose the spectral range. Short-wave ranges generally suit metals, ceramics, glass melt, and flames; longer-wave ranges suit non-metals, flue gas, and glass surfaces.
- Consider response time. Fast-moving targets and control loops need faster response.
- Plan sighting and optics. Laser sighting, a viewfinder, or a camera module helps alignment; fixed, manual, or motorised focus affects flexibility.
- Think about outputs and integration. Switching outputs, analogue or digital interfaces, Ethernet, and PID control matter for automation.
- Plan for the environment. Heat, dust, and vibration may call for protective housings and air purge.
- Plan calibration. Pyrometers need periodic verification; Sensortherm offers calibration and adjustment service and calibration sources.
A Note on Limits
Non-contact measurement has limits worth knowing:
- Pyrometers don’t measure through materials that block infrared radiation (they can measure through windows only if the window’s transmission properties are known and constant).
- Emissivity errors affect 1-color readings, so set it correctly.
- Dust, smoke, and dirty optics reduce signals, which 2-color designs tolerate better, within limits.
- Sensortherm’s models start at around 50 °C, so very low-temperature general measurements may need a different type of instrument.
When in doubt, send the application details to Telos Instruments for review.

Frequently Asked Questions
For hot, moving, or hard-to-reach industrial targets, an infrared pyrometer. A 1-color model suits stable conditions with known emissivity, and a 2-color model suits uncertain emissivity or dusty, smoky views.
Telos Instruments, based in Al Uthman Building, Deira, Dubai, is the exclusive distributor of Sensortherm in the UAE and GCC.
A 1-color pyrometer measures in one spectral band and needs the target’s emissivity set correctly. A 2-color pyrometer uses the ratio of two bands, so it tolerates unknown or changing emissivity and partial obstruction.
Short-wave 1-color or 2-color pyrometers are commonly used for metals. Sensortherm METIS models cover wide ranges (some up to 3300 °C), and 2-color models help when emissivity is uncertain. A heavy-duty measuring system suits harsh conditions. An application review is recommended.
