UNI-T UTi740MS Smartphone Thermal Imaging Camera for iPhone/ Android

The UNI-T UTi740MS is a compact thermal imaging camera module for Android and iOS smartphones (USB-C) with 400 × 300 pixel IR resolution and manual focus. The module turns any compatible smartphone into a professional thermal imaging device without its own battery – power is supplied directly via the smartphone's USB-C port. The super-resolution function improves image quality in real-time to 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 smartphone thermal imaging camera class
• Compatible with Android and iOS via USB-C – battery-free, plug-and-play with the "Thermal Mobile" app, no cloud registration required
• Manual focus via focus ring for precise focusing over various measurement distances – advantageous over fixed focus systems for near and far 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 separate charger or spare battery

Application examples:

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