PG200N Handheld PAR Meter


The PG200N is a lightweight, portable, and easy-to-operate Spectral Light Meter or Spectral PAR Meter designed for agriculture and horticulture applications. It is an interactive system and offers analytical reporting for spectrum, PPFD, PFD, auto-monitoring, and other parameters needed to understand ambient light conditions for plant growth and the adjustment of artificial light sources to efficiently control production, safety, and yield.
