The StellarRAD™ Series 3 is a rugged, turn-key solution for portable light measurement. This handheld radiometer is an easy-to-use research-grade spectrometer for field testing of lights with no additional setup required. The NIST traceable system can measure spectral Irradiance & Illuminance, CCT, xy chromaticity, CRI, PAR, and much more!
Compared to other handheld colorimeters, the StellarRAD utilizes a research-grade spectrometer with <1nm spectral resolution, making these instruments the first choice in reliable testing, field demonstrations, installations, R&D, and quality control.
Reliably measure light output in Lumens/m^2 (Lux), Watts/m2, PAR, PPFD, and Footcandles
1931 CIE Chromaticity Diagram for xy Chromaticity, Dominant Wavelength, Purity, Correlated Color Temperature (CCT), & Color Rendering Index (CRI)
Includes NIST Certificate of Traceability and delivered with all calibrations preloaded ready to use
Includes Solar Monitoring App with solar and grow light classification
Add lens, aperture, and collimating tube attachments for increased functionality
