Pixfra Mile 3 M325 (384x288) Thermal Imager - 25mm

Pixfra Mile 3 M325 Thermal Imaging Monocular

The Pixfra Mile 3 M325 is a compact thermal imaging monocular built around a 384 × 288 vanadium oxide detector and a 25 mm F0.9 objective lens. Its ≤15 mK thermal sensitivity, PIPS 3.0 Pro image processing and 50 Hz frame rate deliver detailed thermal images across a detection range of up to 1,300 metres.

A lightweight magnesium alloy body, integrated three-function control wheel and replaceable 18650 battery system make the M325 practical for prolonged handheld observation. Video recording with audio, still-image capture and 64 GB of built-in storage provide extensive options for documenting observations.

Detailed Thermal Imaging

The M325 combines a 12 μm pixel pitch with class-leading ≤15 mK NETD sensitivity, helping it distinguish small differences in temperature under challenging environmental conditions. PIPS 3.0 Pro processing enhances fine detail, reduces image noise and improves detector responsiveness in colder conditions.

Its 25 mm focal length provides an 11° × 8.2° field of view, equivalent to 19.3 × 14.3 metres at 100 metres. A one-metre close-focus distance supports observation at shorter ranges, while the 1,300-metre detection capability extends its reach across open ground.

OLED Display and Viewing Options

The 0.49-inch OLED display has a resolution of 1920 × 1080 pixels. Six selectable colour palettes allow the thermal image to be adapted to different subjects and conditions: White Hot, Black Hot, Iron Red, Alarm, Green Hot and Sepia.

The monocular offers 1.8× visual-equivalent magnification with 1× to 8× digital zoom. A dioptre adjustment range of -5 D to +3 D and 15 mm eye relief allow the viewing system to be adjusted to the user.

Compact Construction and Handling

Measuring 160 × 52.6 × 50.5 mm and weighing no more than 300 g, the M325 is designed for comfortable handheld use and easy storage in a pocket or pack. Its magnesium alloy body provides a durable yet portable construction.

The integrated three-function control wheel brings focus, magnification and menu navigation together in one control, supporting convenient one-handed operation. Additional functions include picture-in-picture, hot-spot tracking, an electronic compass and automatic, semi-automatic or manual FFC calibration.

Weather Protection and Power

An IP67 protection rating equips the M325 for use in demanding outdoor conditions. It is specified for operation in temperatures from -30°C to 55°C and humidity levels of up to 95%.

The quick-change power system uses rechargeable 18650 lithium batteries. Battery operating time is rated at a minimum of 5.5 hours at 25°C with Wi-Fi switched off, while USB Type-C connectivity supports a 5 V DC power supply.
