MQ-100 Apogee QUANTUM METER (Integrated Sensor)

Basic hand held MQ-100 meter with integrated sensor.
Measures photosynthetically active radiation (PAR), which is more specifically referred to as the photosynthetic photon flux (PPF).
Specify calibration for use in natural (sun) or electric light.

Apogee quantum sensors measure photosynthetically active radiation. The MQ-100 has a sensor integrated into the top of the housing while the handheld meter displays and stores measurements. 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.
