Apogee PAR-FAR Sensor S2-141

A two-channel sensor that measures both PAR (400 to 700 nm) and far-red (700 to 750 nm) wavelengths. This split helps growers evaluate fixtures that include far-red output and supports more informed light-recipe tuning. It is designed for continuous, reliable measurement in both indoor and outdoor environments.

This product includes the Aranet Apogee Transmitter, the Apogee PAR-FAR Sensor (S2-141), and the Apogee Solar Mounting Bracket with Leveling Plate (AL-120).
