Pixfra Arc A613 PRO (640x512/12µm) Thermal Imager

Pixfra Arc A613 Pro Thermal Performance

The Arc A613 Pro uses a 640×512, 12µm vanadium oxide uncooled thermal detector with a thermal sensitivity of less than 18mK NETD. This high level of sensitivity is designed to maintain reliable thermal detection even when weather conditions make temperature differences harder to distinguish.

A 13mm f1.0 objective lens extends detection capability to as far as 700 metres, while the 50Hz frame rate helps maintain a fluid image when following moving wildlife or scanning an observation area.

Wide Field of View

With a 32.3° horizontal and 25.8° vertical field of view, the Arc A613 Pro provides broad scene coverage while retaining useful longer-range detection performance. This makes it particularly suitable for ecological surveys, bat observation, monitoring woodland and estate boundaries, and general nocturnal wildlife observation.

The wider visible area can also make recorded survey data more informative by allowing more activity to remain within the scene at any one time.

Magnification & Close Focus

The Arc A613 Pro provides 1.1x native magnification together with 1x, 2x, 4x and 8x digital zoom settings. A minimum close focus distance of 0.5 metres also provides flexibility when observing subjects at shorter distances.

Pixfra Arc A613 Pro Display & Viewing

Thermal imagery is presented on a 0.41-inch OLED display with a 1440×1080 resolution. The high-resolution display is designed to provide a crisp, clear view of the thermal image, while a -4D to +5D diopter adjustment allows the eyepiece to be tailored to the user's eyesight.

Six colour palettes are available: white hot, black hot, iron red, alarm, amber and emerald. Hot spot tracing is also supported, providing an additional tool for identifying warmer areas within the observed scene.

Pixfra Arc A613 Pro Connectivity

Built-in Wi-Fi allows the Arc A613 Pro to connect to the free Pixfra app for Android and iOS devices. Up to four smartphones or tablets can connect at the same time, allowing several people to observe the live thermal image simultaneously from within 20 metres of the monocular.

This makes the Arc A613 Pro particularly useful for collaborative surveys and group observations, removing the need for multiple users to take turns looking through the viewfinder.

Pixfra Arc A613 Pro Construction & Field Use

The Arc A613 Pro retains a compact, ergonomically designed body with conveniently positioned controls for straightforward handheld operation. At 370g excluding the battery, it remains lightweight enough for prolonged field use and easy transport in a pocket or pack.

A magnesium alloy casing provides protection against everyday knocks and scrapes, while an IP67 protection rating helps safeguard the device against water ingress in wet conditions. It is also designed to operate across temperatures from -30°C to +55°C.

Battery Performance

The Arc A613 Pro uses a rechargeable 3,200mAh 1850 lithium battery, delivering up to six hours of operating time. Two replaceable rechargeable batteries are supplied, allowing one battery to be exchanged for the other during longer observation sessions.

The device also supports a 5V Type-C power supply.
