Thermal imaging has become an indispensable tool for electronics enthusiasts and professionals alike, allowing for detailed inspection and analysis of printed circuit boards (PCBs) and electronic components. In this review, we take a closer look at the Infiray P2 PRO, a compact and affordable thermal camera that promises to deliver impressive performance for PCB inspection tasks.
Designed specifically for PCB work, the Infiray P2 PRO stands out with its high-resolution 256×192 pixel sensor and a blistering 25Hz refresh rate, ensuring smooth and detailed thermal imaging. With a temperature range spanning from -20°C to a scorching 550°C, this camera is well-equipped to handle even the most demanding applications.
One of the key highlights of the P2 PRO is its optional macro lens, which allows for incredibly close-up inspections of PCBs and individual components. With a working distance of approximately 30mm, you can easily identify hotspots and thermal anomalies on silicon dies, IC packages, and even tiny 0402 resistors – a capability unmatched by many competing products in this price range.
The camera’s compact size and included USB-C extension cable make it highly versatile, allowing you to easily maneuver it into tight spaces and enclosures for thorough inspections. The intuitive Android app offers a wealth of features, including multiple color palettes, emissivity and ambient temperature adjustments, and advanced measurement tools like spot, line, and area measurements.
While the P2 PRO doesn’t offer image merging capabilities found in higher-end thermal cameras, it does provide a picture-in-picture mode for general orientation. Additionally, the ability to record video and audio simultaneously proves invaluable for documenting your findings and observations. Compared to alternatives like the UNI-T UTI260B, which lacks a dedicated macro lens out of the box, the Infiray P2 PRO shines in its out-of-the-box readiness for PCB inspection tasks.
Its combination of high resolution, macro capabilities, and user-friendly software make it a compelling choice for hobbyists, repair technicians, and electronics professionals on a budget.
