Apogee Instruments MQ-610 400-750nm ePAR metre

Product detailed description

It has been found that laboratory measurements of the newly defined wavelength range 400-750 nm (ePAR) are more photosynthetically active than the traditional wavelength range 400-700 nm (PAR). The MQ-610 instrument can accurately measure far-red photons (700-750 nm), which occur in many new-generation LED fixtures, in sunlight and in other light sources, and which cannot be measured by traditional PAR metres.
