Description

The HIKMICRO B21L is a pure thermal imaging camera for capturing infrared images.

It detects temperature changes and measures in real time for the central, hot and cold point respectively.

3 measuring points are user-definable, 4 colour palettes are available for display.

A laser pointer facilitates precise targeting of the desired measurement area.

For live viewing and recording, the 16 GB internal memory provides space for approx. 90,000 images. Can be installed on a tripod using a standard thread

Enhanced Thermal Clarity with SuperIR

Powered by HIKMICRO SuperIR image enhancement technology, it upscales the resolution of captured thermal images to 320 x 240 (76,800 Pixels) (after firmware version V5.5.50)

Macro option

With the optionally available macro lens, the thermal imaging cameras can also be used for detailed thermal images of smaller objects and circuit boards.

Wide angle

With a wide-angle lens, the HIKMICRO B20 (B20S) and B21L offer a field of view of 50° × 37° and are ideal for scanning walls, floors and facades to detect problems such as water leaks, insulation problems and air pockets. With the optional macro lens, the thermal imaging cameras can also be used for detailed thermal imaging of smaller objects and circuit boards.

Smooth display with 25 Hz

The high frame rate of 25 Hz ensures that thermal video recordings are smooth and jerk-free and that no detail is lost in the recording.

High Image Quality

Features a highly sensitive (NETD < 40 mK) VOx detector, along with optimized image enhancement algorithms to provide clear thermal images.

4 Images Modes (B20, B20S only)

Thermal, Fusion, PIP, and Optical modes to suit your preferred view.

Measurement

Supports capture of full-screen radiometric images and automatically tracks max/min/center spots to pinpoint temperature anomalies at a glance. Accurately measures temperatures from -20 °C to 550 °C ( -4 °F to 1,022 °F) with a temperature accuracy up to +/-2 °C (+/-3.6 °F) or +/-2 % of reading.

Wi-Fi

Connect to mobile devices via built-in Wi-Fi and the HIKMICRO Viewer App to quickly share your images.

Macro mode

Using a clip-on macro lens, the B series cameras can see details as small as 500 microns and allow you to take accurate temperature readings on small objects, such as components on printed circuit boards or assemblies. The maximum permissible temperature of the measured object is 150 °C.

High Temperature Alarm

Built-in speaker and flash light give the operator audio and visual alerts to high temperatures.

HIKMICRO Analyzer Software

Included software offers flexble ways (points, lines, rectangles, circles, polygons) to analyze thermographic info of captured pictures, and generate reports. The live function is currently not supported in Analyser. You can use software that supports the UVC protocol if you want to broadcast the screen.
