UNI-T UTi740M Smartphone Thermal Imaging Camera for Android

The UNI-T UTi740M is a compact thermal imaging camera module for Android smartphones (USB-C) with 400 × 300 pixel IR resolution and manual focus. The module turns any compatible Android smartphone into a professional thermal imaging instrument without its own battery – power is provided directly via the smartphone's USB-C connection. The super-resolution function improves image quality in real-time up to 800 × 600 pixels through software interpolation.

Features:

• 400 × 300 pixel IR resolution (VOx detector) with super resolution up to 800 × 600 pixels in real-time – highest resolution in the Android smartphone thermal imaging camera class
• Exclusively for Android via USB-C – battery-free, plug-and-play with “Thermal Mobile” app without cloud registration or driver installation
• Manual focus via focus ring for precise focusing at various measurement distances – beneficial for both close-ups and long-range inspections
• Temperature measurement range -20 to 550 °C with ±2 °C or ±2% measurement accuracy and thermal sensitivity ≤45 mK at 25 °C
• Seven color palettes, PIP mode, fusion mode, and up to five simultaneous measurement points in the “Thermal Mobile” app for flexible image analysis
• Compact, battery-free design – ideal for mobile field inspections without a separate charger or spare battery

Application examples:

• Building inspections for thermal bridges, missing insulation, and moisture in walls and ceilings with Android smartphone integration
• Electrical inspections of distribution boxes, switches, and fuses for early detection of overheating without de-energizing
• HVAC diagnostics on heaters, air conditioners, and heat pumps for leak and flow analyses
• Photovoltaic inspection: Detection of defective solar cells and hot spots on PV modules directly with the Android smartphone
• Product development and quality assurance for temperature profiles of electronic assemblies and circuit boards in the laboratory
