The CTlaser MT is engineered to facilitate non-contact temperature measurement through flames, covering an extensive temperature range from 200 °C to 1650 °C. The infrared sensors versatile applications include monitoring workpieces inside fire-heated ovens, measuring within chemical reactors, and observing brick temperatures in combustion chambers. These pyrometers offer a spot size starting from 1.6 mm, ensuring precision in temperature readings. With a distance to spot size ratio of 45:1 and a two-piece sensor design, these infrared thermometers guarantee configurability and ease of use, enhancing its suitability for various industrial settings.
One notable aspect of the CTlaser MT is the infrared sensors spectral range of 3.9 μm, accommodating temperature ranges of 200 °C … 1450 °C for the standard MT model and 400 °C … 1650 °C for the MTH model. This broad temperature measurement range allows for accurate and precise temperature measurement through flames and combustion gases, making these pyrometers an indispensable instrument in heat treating applications where long wavelength infrared and visual cameras is impractical. The online pyrometer offers a system accuracy of ±1% and repeatability of ±0.5% or +0.5 °C.
A distinguishing feature of the CTlaser MT series is its incorporation of double laser aiming marks, which ensure precise aiming and minimize alignment issues. This innovative system utilizes two laser beams to trace the infrared optical path accurately, indicating the spot’s position and size depending on the distance. This feature enhances the reliability and accuracy of temperature measurements, even in challenging environments such as flame-heated furnaces.
The two-piece design of the CTlaser MT includes a separate electronics box, enabling advanced signal processing capabilities. Offering a wide range of analog and digital outputs, including 0/4 – 20 mA, 0 – 5 V, 0 – 10 V, USB, RS485, RS232 interface, relay outputs (2 x optically isolated), Profibus DP, Modbus RTU, Modbus TCP, Profinet, and EtherNet/IP, it ensures seamless integration into various industrial processes and control systems.
Operational in ambient temperatures up to 85 °C without requiring additional cooling, the CTlaser MT includes an automatic laser shut-off feature at 50 °C, ensuring little power usage. Additionally, the pyrometer can be enhanced with Optris accessories such as air purging, cooling jackets, and mounting flanges, further expanding the infrared sensors applicability in diverse manufacturing and annealing process applications.
Manufactured and calibrated in Germany, the CTlaser MT pyrometers undergo meticulous calibration processes to meet stringent government standards such as PTB or NIST, ensuring accuracy and reliability. Customization options such as different cable sizes are available to accommodate specific customer requirements, enhancing flexibility and usability.
Optris provides comprehensive support for the CTlaser MT series, including consultation on industrial applications and after-sales support, ensuring optimal performance and user satisfaction. With its precision, versatility, and reliability, the CTlaser MT proves to be a valuable instrument for temperature measurement in various glass processing applications and beyond.

Thermography software optris PIX Connect is included and license-free.All infrared cameras are delivered with the thermography software optris PIX Connect, developed specifically for the extensive documentation and analysis of thermal images. The Windows-based PIX Connect software enables users to tailor the infrared cameras to meet specific requirements. It analyses live and recorded temperature data and triggers alarm signals for process integration. The key to leveraging the Optris infrared camera is a correct configuration. This includes detailed device-specific configurations such as frame rate, measurement range adjustments, external communication settings, and USB/Ethernet configurations. Moreover, PIX Connect facilitates firmware updates and the download of configuration files over the Internet.
Optris offers several different SDKs for our Xi and PI thermal imaging cameras. Depending on the operating platform, the infrared camera, the coding language, and the hardware platform, different software interfaces can be utilized:
The Optris IRmobile allows users to set up and commission an Optris infrared pyrometer or infrared camera with an Android smartphone or tablet. This tool becomes handy for commissioning and aligning the infrared camera’s field of view or adjusting the configuration. The app analyzes the connected infrared camera‘s live infrared image stream with auto hot and cold spot detection. For pyrometers, a temperature-time diagram or the video signal is displayed. This app works on most Android devices running 5.0+ with a USB port supporting USB-OTG (On The Go).
