Pixfra PFI-M625 LRF Thermal Monocular Camera Review

The Pixfra PFI-M625 LRF Thermal Monocular Camera brings thermal viewing and laser distance measurement together in a portable device. Its combination of a 640 × 512 detector, broad viewing coverage and integrated recording makes it an option for users who want to observe, measure and capture with one monocular.

Performance & Key Features

The 25 mm F1.0 lens provides a 17.4° horizontal field of view, covering 30.6 m at 100 m, alongside 1.2× visual equivalent magnification. A 50 Hz frame rate, ≤15 mK NETD sensitivity at F1.0 and PIPS 3.0 Pro technology form the core imaging specification. The laser rangefinder adds distance measurement to 1,000 m with ±1 m accuracy, distinct from the 1,300 m thermal detection distance. Six palettes, picture-in-picture and digital zoom provide further viewing options.

Build Quality & Handling

The magnesium alloy body and IP67 rating provide the main durability credentials, with operation specified between -30°C and +55°C. Dimensions of 167.7 × 61.4 × 50 mm and a net weight of no more than 313 g keep the design compact. A quick-change 18650 battery allows replacement when required.

Is It Easy to Use?

The three-function control wheel brings several controls together, while dioptre adjustment accommodates eyepiece focusing. Lens focus is manual, and users can choose automatic, semi-automatic or manual FFC calibration. Built-in video recording, snapshots and a local album keep capture and review functions within the monocular.

Key Takeaways

The PFI-M625 LRF combines a 640 × 512 thermal detector, wide viewing coverage and laser ranging in a compact body. Its 1.2× visual equivalent magnification is modest, with additional enlargement supplied by digital zoom. Battery endurance is rated at at least five hours at 25°C with Wi-Fi off. For Uttings customers seeking portable thermal observation with integrated distance measurement and recording, it is worth considering.
