• Wide -20°C to 550°C temperature range with ±2°C / 2% accuracy
• 3.2" LCD display (240 × 320 resolution) for clear visual feedback
• Real-time max, min, and centre spot tracking
• Macro lens allows readings from objects as small as 0.5 mm
• Selectable palettes: White Hot, Black Hot, Rainbow, Ironbow
• Built-in high-temperature alarm with LED torch and speaker alert
• Wi-Fi image streaming to mobile devices via HIKMICRO Viewer App
• Built-in 16GB memory stores approx. 90,000 radiometric images
• Rechargeable Li-ion battery with up to 6 hours of continuous use
• IP54 rated, drop tested to 2 m, and tripod mountable

Accurate imaging and SuperIR enhancement

The B21L features a high-quality 256 × 192 infrared detector supported by a VOx sensor and advanced algorithms to deliver stable, fully radiometric images. SuperIR further boosts captured image detail to 320 × 240 pixels, allowing for finer thermal contrast and post-capture analysis. A 3.6 mm focus-free lens with a 50° × 37.2° field of view makes it easy to scan broad surfaces such as walls, motors, or breaker panels. It measures temperatures from -20°C to 550°C with ±2°C accuracy, highlighting hot and cold spots automatically during scans.

Tools designed for inspection professionals

Ideal for HVAC, electrical, and mechanical work, the B21L includes an onboard Class II laser pointer and macro lens attachment, enabling accurate measurements from as close as 30 cm. Macro mode allows reliable imaging of small components like fuses and PCBs, measuring surface temperatures on targets as small as 500 μm. With up to 90,000 images storable on the built-in 16GB flash memory, it simplifies inspection documentation and analysis. The user interface supports multiple measurement points, automatic level/spanning, and selectable colour palettes to match each job.

Connectivity, durability, and reporting

The B21L wirelessly connects to the HIKMICRO Viewer App for live image streaming and snapshot review on your phone or tablet. Reports can be created with the included HIKMICRO Analyser software, helping streamline communication with teams or clients. It runs for up to 6 hours on a single charge, is drop-tested to 2 m, and is IP54 rated for protection against dust and water. A tripod thread also allows for stationary thermal monitoring.

FAQs

How does the SuperIR function improve the HIKMICRO B21L’s image quality?

SuperIR enhances the standard 256 × 192 resolution of captured thermal images to 320 × 240, significantly improving clarity when viewing or analysing results. This feature is particularly useful for identifying small anomalies in post-inspection workflows without increasing the file size or affecting device performance.

Can the B21L measure small components?

Yes, the B21L includes a clip-on macro lens that allows temperature readings from as close as 0.3 m and can detect thermal differences in objects as small as 0.5 mm. This makes it highly effective for electronics, PCB work, or detailed mechanical inspections.

What are the wireless capabilities of the B21L?

The B21L connects via Wi-Fi to the HIKMICRO Viewer App, allowing users to stream live thermal images directly to a smartphone or tablet. This is helpful for remote viewing, sharing images with team members in real time, and reviewing results on a larger screen during inspections.

Is the B21L suitable for field use in tough environments?

Absolutely. With IP54 protection against dust and water splashes, a 2 m drop resistance rating, and a rugged handheld design, the B21L is built for daily use on job sites. The rechargeable battery lasts up to 6 hours, and its compact form factor ensures it’s easy to transport and deploy quickly.

Can the B21L create reports from inspection data?

Yes. Thermal images and radiometric data captured on the B21L can be analysed and compiled using HIKMICRO Analyser software. This tool enables users to document issues, annotate images, and generate professional thermal reports for client handover or internal diagnostics.
