Item #: APG-MQ-200
Shipping: Eligible for Free Shipping Program
Availability: Out Of Stock


Apogee quantum sensors measure photosynthetically active radiation. The MQ-200 has a handheld meter to display and store measurements with a separate sensor head connected by a lead. The sensor head features a fully potted, domed-shaped design making it fully weatherproof, waterproof and self-cleaning. The head can be held by hand, mounted to a leveling plate, or attached to an optional sensor wand for taking measurements in hard to reach places. Photosynthetically active radiation (PAR), or photosynthetic photon flus (PPF), is the wavelength range from 400 to 700 nanometers and is strongly correlated with plant growth. Gardeners, greenhouse managers, growth chamber users and salt-water aquarists measure PAR to ensure optimal specimen health.
