Compact handheld thermal camera with a visual camera and a 640 × 480 screen
The B20S is the everyday handheld in the HIKMICRO range: a 256 × 192 thermal detector, a 2 MP visual camera and a 3.2-inch 640 × 480 screen in a body that survives a 2 m drop. It is focus-free, so there is nothing to set before reading, and the wide 37.2° × 50° lens takes in a full switchboard or wall section at once. Wi-Fi sends images to a phone; the optional clip-on macro lens takes it down to 500 micron detail.
Key features
-
256 × 192 VOx detector — NETD < 40 mK, with SuperIR on live view and captured images
-
2 MP visual camera — thermal, visual, fusion and PIP modes make the hotspot easy to place in the real scene
-
3.2" 640 × 480 display — high-resolution preview so faults are visible on the camera, not just back at the office
-
Wide 37.2° × 50° focus-free lens — covers a full switchboard or wall section from 0.3 m upwards, with nothing to adjust
-
−20 °C to 550 °C measurement range — accuracy ±2 °C / ±2 %
-
Macro capability — with the optional HM-B201-MACRO clip-on lens, resolves detail down to 500 microns
