Quantify Your UV LED Performance—Precisely
The LS131 UV Energy Meter captures both irradiance (mW/cm²) and energy (mJ/cm²) in a single pass, delivering laboratory-grade insight into LED curing lines, UV exposure units and 3D-printing stations.
Key Advantages
- Wide 0-40 W/cm² Range—suitable for high-power 365 nm, 375 nm, 385 nm, 395 nm & 405 nm LEDs.
- Real-Time Power Curve—analyze intensity uniformity across conveyors or point sources.
- 100 °C Heat-Shield Design—place directly inside curing ovens without damage.
- 60 000-Point Memory + Timer—log up to 32 min; view last test automatically at start-up.
- PC Report Software (USB)—export to Excel & one-click PDF for QA documentation.
- Field-Replaceable 4 × AAA—no downtime waiting for rechargers.
- Factory Calibration Report + 12-Month Warranty included.
Best-Fit Applications
- UV LED conveyor & spot curing lines (adhesives / coatings)
- 3D-print resin post-curing boxes
- PCB / solder mask exposure systems
- UV flatbed & inkjet printing QA
- Fiber-optic & optical component bonding
