Apogee Instruments Red - Far-Red sensors combine two photodetectors designed to measure the wavelength ranges and peaks of red and far-red light, which influence photosynthetic and morphogenic activity. — Two-channel sensor for measuring the Red / Far-red ratio (RFR) for ecological applications, including the effect of spectral quality on phytochrome. The RF ratio influences plant height, leaf expansion rates, and other photobiology and plant morphogenic responses.

This sensor is a research-grade, cost-effective two-channel sensor for monitoring plant light environments, including calculation of the red to far-red ratio (red photon flux density / far-red photon flux density) and far-red fraction (far-red photon flux density / sum of red and far-red photon flux densities).

Spectral Response

The red - far-red sensor has a spectral range of 645 to 665 nm ± 5 nm (red) and 720 to 740 nm ± 5 nm (far-red). The spectral responses can be seen in the graph below.

Rugged, Self-cleaning Housing

The patented 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.

Typical Applications

Applications include monitoring plant light environments, researching plant morphogenic activity, and photobiology studies.

Mounting

TheAL-120 Solar Mounting Bracket with Leveling Platefacilitates mounting the 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.

Output Options

Available as an analog output or in digital SDI-12 or Modbus communication protocols.

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
