The Thermal Master T2S Pro is a professional macro thermal camera that transforms your iOS smartphone into a high-precision temperature measurement tool. With a 256 × 192 IR resolution and a frame rate of 25Hz, it delivers sharp thermal images with excellent responsiveness. Its standout feature is the 8mm adjustable macro lens (“Smart Spin”) that allows manual focus for extreme close-up inspections, making it ideal for detecting tiny components such as 0.25mm resistors.
The camera operates in a wide temperature range of -20 to 450°C with an accuracy of ±2°C or ±2% and a NETD of ≤40mK. It’s suited for various applications, including detailed PCB analysis, HVAC troubleshooting, electrical system diagnostics, and structural inspections. Features include customizable measurement ranges, dual-range view modes, digital zoom (up to 15×), and support for picture-in-picture and fusion modes for advanced thermal visualisation.
This is the iOS version with a lightning connection. There is also an Android version with a USB-C connection.
