Apogee Instruments PRI sensors provide an indication of canopy photosynthetic activity. — Cost-effective remote measurement of Photochemical Reflectance Index (PRI)

Spectral Response

The PRI Sensors have the spectral ranges of 532 nm with 10 nm full-width half-maximum (Green) and 570 nm with 10 nm full-width half-maximum (Yellow). The spectral responses can be seen in the graph below.

Rugged, Self-cleaning Housing

The domed shapped sensor head (diffuser and body) facilitates runoff of dew and rain to keep the sensor clean and minimizes errors caused by dust blocking the radiation path. Sensors are housed in a rugged, anodized aluminum body and electronics are fully-potted.

Mounting

TheAL-120 Solar Mounting Bracket with Leveling Platefacilitates mounting the upward-looking sensor to a mast or pipe. TheAL-100 Solar Sensor Leveling Plateis designed to level the sensor while sitting on a flat surface or mounting to a surface. TheAM-400 Two Band Radiometer Mounting Bracketis designed to mount the downward-looking sensors to a mast or pipe.

Output Options

Available in digital SDI-12 output or with an analog output.

High Quality Cable

Pigtail-lead传感器特性IP68,玛丽ne-grade stainless-steelcable connectorsbuilt directly into the sensor head to simplify sensor removal for maintenance and recalibration. Cable is shielded-twisted-pair wire with a TPR jacket for high water resistance, UV stability, and flexibility in cold conditions.

Warranty and Support

All Apogee products are backed by an industry-leading four year warranty and outstanding customer support
