PPFD measurements over plant canopies in outdoor environments, greenhouses, and growth chambers. The cable is shielded-twisted pair wire with a TPR jacket for high water resistance, UV stability, and flexibility in cold conditions. Pigtail-lead sensors feature an IP68, marine-grade stainless-steel cable connector approximately 30 cm from the head to simplify sensor removal for maintenance and recalibration. Sensors are also available attached to a hand-held meter with digital readout. Output OptionsĪpogee currently offers one analog model available for sale on our website with multiple outputs and measurement ranges coming soon. The AL-100 Solar Sensor Leveling Plate is designed to level the sensor while sitting on a flat surface or mounting to a surface. ![]() ![]() The AL-120 Solar Mounting Bracket with Leveling Plate facilitates mounting the sensor to a mast or pipe. The full-spectrum sensors are pre-calibrated for all light sources. To ensure accuracy each sensor is carefully calibrated in controlled conditions and traceable to NIST reference standards. The extended spectral response increases the accuracy of LED measurements. The Extended Range PFD sensor (model SQ-620) has a spectral range of 340 to 1040 nm ± 5 nm. The ePAR has a better spectral match the wavelengths of light that are photosynthetically active so it is a superior product to the ePFD sensor, and can be used under any kind of light. ![]() It is being replaced by the “ ePAR” line which measures from 380 – 760 nm. This particular sensor should only be used for photon flux density measurements under LEDs.Īpogee are discontinuing the “ePFD” line of sensors and meters that measures from 340 – 1040 nm. The 1040 nm top cutoff also means the sensor will measure the thermal output of HPS fixtures and other broad-spectrum lights above the range that influences plants therefore, the sensor is intended only for use in LED environments. The extended range filter of the SQ-620 allows it to measure photons from UV and Far-red. Research has shown the value of adding UV and far-red LEDs to achieve various disease control and photomorphogenic effects. Description Measure photon flux density (PFD) from 340-1040 nmĪpogee’s new extended-range photon flux density (PFD) sensors are for measuring the newest generation of LED grow lights with wavelengths outside the traditional 400-700 nm PAR range.
