Description
Thermal-only handheld camera with laser pointer — the lower-cost B-series option
The B21LS is the thermal-only version of the B-series handheld. It drops the visual camera the B20S carries and adds a laser pointer instead, which keeps the price down while retaining the same 256 × 192 detector, the same 640 × 480 screen and the same 550 °C ceiling. For electrical, HVAC and building work where you need the temperature and a clear thermal image rather than a fused photograph, it does the job for noticeably less.
Key features
- 256 × 192 VOx detector — NETD < 40 mK, with SuperIR upscaling captured images to 640 × 480
- Thermal-only design — no visual camera — this is the deliberate difference from the B20S, and where the saving comes from
- Laser pointer — marks the centre measurement point on the actual object
- 3.2" 640 × 480 display — high-resolution preview for on-site decisions
- Wide 37.2° × 50° focus-free lens — full switchboards and wall sections in one frame, 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
- Speaker and flashlight alarms — audible and visual warning when a temperature threshold is exceeded
- Wi-Fi image transfer — to HIKMICRO Viewer; analysis and reporting in HIKMICRO Analyzer on PC
- IP54, 2 m drop, 6 hours runtime
Typical applications
- Electrical panels, breakers, busbars and cable terminations
- Preventive maintenance on motors, bearings, pumps and drives
- HVAC commissioning and fault finding
- Building envelope surveys — insulation gaps, thermal bridges, air leakage
- Underfloor heating loops and concealed pipework
- Damp, leak and water ingress tracing
- Solar PV panel and inverter inspection
- Documented condition reports for clients and insurers
