SpotOn - Quantum PAR Light Meter

Brand: SpotOn

SpotOn Quantum PAR Light Meter

The SpotOn Quantum PAR Light Meter from Innoquest gives scientifically accurate photosynthetically active radiation (PAR) readings under any light source, including LED, in a compact handheld meter. Each meter is calibrated to a NIST traceable light sensor on a broad-spectrum light source and reads from 0.0 to 6,500 umol/m2/s with +/- 5 percent accuracy.

Three modes cover daily work: instant spot measurement for PAR readings, scan mode for quickly averaging PAR over an area, and DLI mode, which shows the daily light integral on the LCD with no computer needed. An integral mounting plate supports stand, stake, lanyard, hanger and magnet mounts, and a 1/4-20 threaded hole fits camera tripods and stands, so the meter can be handheld or left in place to track DLI in a greenhouse or grow room.
