Guide TK421 Thermal Imaging Monocular

A thermal imaging monocular with an infrared detector equipped with a 25 mm lens to facilitate observation both during the day and at night.

The thermal imager is equipped with a sensor with a resolution of 400 × 300 pixels, with a pixel spacing of 17 μm. The 0.4-inch display with a resolution of 1280 × 960 pixels makes the image clearer and softer, which affects the comfort of observation. The FLCOS anti-fog eyepiece prevents condensation and evaporation so that the observed object is clear all the time.

The device allows you to use 3 image display modes for easy recognition and identification of the observed objects:
- Natural mode allows comfortable observation of objects without amplification of individual areas,
- Enhanced mode amplifies the brightness of high temperature objects,
- Highlight mode enhances the highest and lowest temperature areas.

The monocular is equipped with 6 color palettes to choose from: White Hot, Black Hot, Iron Red, Blue Hot, Green Hot and Adjustable Red Hot. The device features Picture in Picture mode, which allows you to zoom in on your target and highlight its details.

The TrackIR app (available for Android and iOS) allows for live video streaming. Integrated Wi-Fi and Micro HDMI output allows you to use, for example, a phone with the TrackIR app as an external display.

Built-in rechargeable batteries (2x 18650) with a total capacity of 6,000 mAh allow the thermal imager to operate for up to 5 hours. A built-in USB-C port is used for charging, as well as connecting to an external power bank. 

The body of the thermal imager is made of a shock- and mechanical-resistant material, meeting the IP66 waterproof rating, which provides complete protection against dust ingress and protection against water jets coming from all directions at up to 100 liters per minute.  

The set includes:
- thermal imager,
- charger,
- USB-C cable,
- Micro HDMI cable,
- lens cover,
