Factory-Calibrated High-Temperature Lens for Industrial Process Excellence

The UTi740XH's specialized high-temperature lens (UT-Z052) represents a critical capability for industrial thermographers working with extreme-temperature processes. Unlike standard thermal cameras limited to 1000°C-1200°C (1832°F-2192°F) maximum measurement, the UTi740XH extends thermal imaging capability to an extraordinary 2200°C (3992°F) through its factory-calibrated 18mm high-temperature lens. This calibration is performed at the UNI-T factory with additional high-temperature calibration points to ensure measurement accuracy of ±1.5% across the entire 1000°C to 2200°C (1832°F to 3992°F) range, providing reliable thermal data for critical process control and equipment monitoring applications.

The high-temperature lens features the same 18mm focal length as the standard telephoto lens, providing a 14.6°×10.9° field of view and 0.66mrad spatial resolution optimized for industrial process imaging at safe working distances. Like all lenses in the UTi740X system, the high-temperature lens uses UNI-T's Pre-Cal Technology with a built-in storage IC for automatic recognition and calibration—simply install the lens and the camera handles calibration automatically. Professional thermographers can swap between the high-temperature lens and any of the five standard lenses (standard UT-Z048, wide-angle UT-Z049, telephoto UT-Z050, ultra telephoto UT-Z051, and macro UT-Z053) as inspection requirements change, providing complete flexibility for comprehensive industrial facility surveys that include both extreme high-temperature processes and conventional equipment inspections.

Smart Interchangeable Lens System with Automatic Calibration

Beyond its high-temperature capability, the UTi740XH features the same smart interchangeable lens system as the UTi740X, with automatic lens recognition and calibration across all six lenses. Each lens contains a built-in storage IC that records lens-specific temperature calibration data. When any lens is installed, the camera automatically recognizes it and reads the stored calibration data, completing the entire calibration process without any manual intervention. This Pre-Cal Technology eliminates the traditional requirement of sending the camera back to the factory for recalibration after lens changes, saving significant time and cost while ensuring measurement accuracy is maintained every time you swap lenses.

The complete six-lens system covers every industrial inspection scenario. The 9.6mm standard lens (UT-Z048) provides the ideal balance for general inspections with its 27.7°×20.6° field of view. The 6mm wide-angle lens (UT-Z049) expands coverage to 46°×34° for large equipment surveys. The 18mm telephoto lens (UT-Z050) offers focused 14.6°×10.9° imaging for mid-range targets. The 36mm ultra telephoto lens (UT-Z051) provides an exceptionally tight 7.2°×5.5° field of view for long-range surveys from safe distances. The 18mm macro lens (UT-Z053) enables detailed close-up inspection of small components. This comprehensive lens selection ensures the UTi740XH serves as a complete industrial thermal inspection solution for both extreme high-temperature processes and conventional equipment maintenance.
