Frequently Asked Questions
How does the Super Resolution feature enhance thermal image quality?
The UTi740MS's Super Resolution technology uses advanced algorithms to enhance the native 400×300 pixel resolution to 800×600 pixels, effectively quadrupling the image detail. This enhancement allows the visualization of smaller temperature variations and finer details that would be missed in standard resolution. The increased clarity is particularly valuable when inspecting complex systems with small components or when creating detailed reports for clients, providing professional-level imaging quality in a compact, smartphone-connected device.
What advantages does the manual focus capability provide?
The UTi740MS's manual focus capability allows technicians to adjust the focusing ring to achieve the sharpest possible image at various distances and for different applications. Unlike fixed-focus thermal cameras that may produce blurry images when working outside their optimal distance range, the manual focus ensures clear, accurate temperature readings whether you're inspecting close-up electronic components or distant building elements. This flexibility significantly improves measurement accuracy and detail recognition across a wide range of inspection scenarios.
How does the UTi740MS compare to standalone thermal cameras?
The UTi740MS offers several advantages over traditional standalone thermal cameras. By leveraging your smartphone's processing power and display, it eliminates the need for a dedicated screen and battery, resulting in a significantly smaller, lighter, and more portable device. This smartphone integration also provides superior connectivity options for sharing and reporting, all while maintaining professional-grade specifications like 400×300 pixel resolution, ≤45mK sensitivity, and a wide temperature range. For professionals who already carry a smartphone, the UTi740MS provides comparable performance to mid-range standalone thermal cameras at a fraction of the size and weight.
What are the different isotherm modes used for?
The UTi740MS provides five isotherm modes that help focus analysis on specific temperature ranges: Auto mode automatically highlights the most relevant temperature regions; Below mode highlights areas below a set threshold (useful for finding cold spots or air leaks); Above mode highlights areas exceeding a set temperature (ideal for electrical hotspots); Section mode highlights a specific temperature band (perfect for process monitoring); and Manual mode allows complete customization of the isotherm parameters. These specialized visualization modes help technicians quickly identify areas of interest and create more effective reports by visually emphasizing critical temperature patterns.
