The thermal imaging camera B20 is optimal for electrothermography, mechanical applications (also with higher temperatures) as well as construction thermography. Highlights of the camera are its automatic measuring range change, real-time transfer of the radiometric image to an external tablet or smartphone, a high frame rate of 25Hz for more continuous and stable image viewing, and a three-year warranty.
The camera (IP54 rating) is designed for rapid temperature measurements. It is equipped with a Hikmicro Vox detector with a resolution of 256 x 192 pixels and fixed focus (field of view/FOV 37.2° × 50°) and a visual camera with 2 megapixels. Thus, it also realizes a fusion image or a picture-in-picture, which can also be stored internally on the camera (up to 90,000 images). The measuring ranges extend from ‑20°C to 550°C and change automatically depending on the displayed object temperature. An image overlay function (image fusion — infrared and visual image) provides high detail recognition.
The B20 is just as suitable for electrical inspections as it is for the HVAC sector or for simpler building thermography tasks, e.g. identifying thermal bridges or areas where mold could develop (due to significantly lower temperatures causing humidity to condense there). However, because of its wide measuring range (up to +550°C), applications are also possible wherever rather high temperatures are reached (in the automotive industry, engines, furnaces, heaters and other high-temperature applications).
With its pure thermal image resolution of 256 x 192 (49,152) pixels and a good NETD < 40 mK (at 25 °C), the camera also enables more sophisticated measurements that were not previously standard in this price segment (the recommended retail price is 549€ plus VAT). Another trend-setting feature in this class: the high refresh rate of 25 Hz ensures a clear, jerk-free image (in contrast to the 9 Hz that is often common with simple thermal imaging cameras and which makes inspections not only more tedious but also much more strenuous).
Presets for measurements include spot center, hot spot, cold spot, and preset spot. Manually, different temperature ranges (Level & Span) can be set; certain (more narrowly selected) temperature ranges can result in more clearly discernible details in the thermal image. The large LCD screen (3.2 inches) contributes to the enhanced viewing experience, but with the integrated WLAN, users can also view, save or transfer and share images live on their cell phones. The camera features a USB‑C interface and a UNC ¼”-20 tripod mount. In continuous operation, the batteries last up to 6 hours. An alarm function is also on board: when the temperature exceeds a preset threshold, an audible and visual alarm is triggered.
