The S2-141 PAR-FAR sensor is a unique two-channel sensor for measuring both the PAR (PPFD) and Far-red outputs of electric grow lights and is self-powered. The sensor features a rugged, aluminum housing that is fully-submersible and built to withstand harsh conditions. The sensor cable includes an IP68 marine-grade stainless-steel cable connector to simplify sensor removal and replacement from permanent installations for maintenance and calibration. Typical applications of PAR-FAR sensors include measuring both the traditional PPFD photosynthetic photon flux and separately quantifying the photon flux of far-red photons (700-760 nm). The outputs include the traditional quantum flux, the far-red photon flux, and the far-red fraction (far-red photon flux density / sum of PPFD and far-red photon flux density). This sensor quantifies far-red photons, and for many applications it reduces the need for a more complex measurement with a spectroradiometer.
The analog version of this sensor (S2-141) comes with the inline cable connector placed 30 cm from the sensor head for either standard use as a long cable, pigtail sensor, or for connecting at the cable junction with our microCache Bluetooth Micro Logger.
