PAR Meter

A PAR meter, also known as a “quantum sensor” measures the intensity of light, the amount of electromagnetic radiation below a single source, or multiple sources of light. Using a PAR meter to record instantaneous light (PPFD) allows you to optimize your lighting environment to your specifications. In controlled environment agriculture (CEA), this means the ability to deliver the amount of light your crop requires at any moment, and over the course of a day.
