Temp Master This app is exclusively compatible with the following Thermal Master devices: P1 / P2 Pro / P3. Thermal Master offers two main series of thermal imaging devices—Temp Master (traditional smartphone thermal cameras) and Thermal Master (thermal monoculars)—covering a wide range of use cases from home temperature monitoring and industrial inspections to long-range (up to 1500 meters) outdoor night vision. What's new in this version: Resolved compatibility issues with the X³ super-resolution algorithm on some models. Now fully supports enhanced infrared resolution of 512×384. P2 now supports high-accuracy temperature detection within ±2.7℉ (±1.5℃). With an upgraded IQ+ precision algorithm, temperature readings for HVAC systems, electrical circuits, PCB diagnostics, and automotive inspections are now even more reliable. The P2 pioneered ultra-low power consumption in thermal imaging—just 0.3W. We've further optimized the algorithm, battery life can now reach 5–7 hours or more. Upgraded professional data analysis software: view, save, and export images and temperature data even offline. Enhanced the Razor X image algorithm, reducing background noise by approximately 20% and achieving a frame rate of 25Hz, ensuring smooth performance even during fast movements. All Thermal Master devices now support up to 15x digital zoom for pinpoint accuracy when locating faults. As a global leader in smartphone thermal imaging, Thermal Master is committed to creating smarter and sharper thermal cameras. We hold the largest number of smartphone thermal imaging patents worldwide and offer lifetime free software updates for all products.
