Medidor de mano Quantum MQ-303 de Luz Par y Barra de 50 cm con 3 Sensores de Luz PAR (400-700 nm).
La barra incluye un nivel de burbuja.

Apogee line quantum sensors measure a spatial average of photosynthetically active radiation. The MQ-303 has a separate sensor bar with 3 sensors while the handheld meter displays and stores measurements. The sensor housing design features an integrated bubble level and is fully potted making the sensor weatherproof. Photosynthetically active radiation (PAR), or photosynthetic photon flux (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 insure optimal specimen health.
