Designed for finding faults fast, the Hikmicro B21L Handheld Thermal Camera is an accurate, adaptable infrared imager ideal for building, HVAC, and automotive applications. Equipped with a VOx detector, 256 x 192px IR resolution, 40mk thermal sensitivity, 25Hz frame rate, and image enhancement algorithms, the Hikmicro B21L Handheld Thermal Camera captures clear, smooth radiometric images. It can measure temperatures between -20°C and +550°C to an accuracy of ±2°C/2% and will automatically track the maximum, minimum, and centre temperatures. The Hikmicro B21L Handheld Thermal Camera also includes useful imaging functions such as selectable thermal colour palettes; a High Temperature Alarm; Macro Mode; and SuperIR function. Imaging is indicated on the 3.2-inch LCD and may be streamed via Wi-Fi to a smartphone/tablet with the Hikmicro Viewer App installed. Finally, Hikmicro’s Analyser Software can be used to analyse thermal data and create reports.
