2. Product Overview and Features
The InfiRay P2 Pro is engineered for precision and versatility, offering advanced thermal imaging capabilities in a portable form factor.
2.1 Key Features
- Quick Identification with Magnetic Macro Lens: The P2 Pro includes a magnetic macro lens, enabling close-up observation for detailed analysis of PCBs and microcircuits. This allows for sharp imaging and identification of resistance in the millimeter range.
- Outstanding Performance: Features an IR resolution of 256 x 192 pixels and a fast frame rate of 25 Hz, providing high-resolution thermal imagery. It supports full-frame temperature measurement (Max, Min, Center Spots) across an extensive temperature range from -4 °F to 1022 °F (-20 °C to 550 °C).
- High Accuracy: Offers a measurement accuracy of ±2 °C or ±2% of the measurement range (whichever is greater), suitable for identifying hidden heat-related issues in various settings, including home inspections, HVAC troubleshooting, and professional electrical system checks.
- Batteryless and Secondary Analysis: Operates without an internal battery, drawing power directly from the connected smartphone. Captured infrared images can be used for secondary analysis directly within the software, allowing for point-line-surface analyses.
