PPFFR QUANTUM SENSOR - AQSL-UV912.

The AQUAMATIC Surface PPFFR Quantum Sensor is used as reference sensor for AQPL-UV912 to measure Photosynthetic Photon Flux Rate (PPFFR) in the air.

A specially designed photodiode and a filter are built in to the sensor for linear energy response between 400 and 700 nm having a slope of 1% per 7 nm which is the ideal PPFFR sensitivity.

Features include a rugged and waterproof construction for measurements in air. No moving parts, big black disk as protection against sea reflections, input from all directions, linear energy response with wavelength, equal response to photons between 400 and 700 nm, fast reaction time depending upon automatic range, small dimensions, easy to install, easy to dismount.
