NDVI and PRI Sensors

Apogee offers two types of two-band radiometers to inform environment and plant health; NDVI and PRI sensors.
Apogee's newest two-band sensors provide cost-effective remote measurement of Normalized Difference Vegetation Index (NDVI) and Photochemical Reflectance Index (PRI).
NDVI Sensors

Typical Application
Monitoring plant canopies and is often used to monitor green up in the spring and senescence in the fall.

Spectral Range
650 nm ± 5 nm with 65 full-width half-maximum (Red)
and 810 nm ± 5 nm with 65 full-width half-maximum (NIR).

NDVI sensor spectral response graph.

Output Options
Available with an analog output.

Waterproof

PRI Sensors

Typical Application
Monitoring plant canopies and is often used in studies of canopy photosynthesis and response to stress.

Spectral Range
532 nm with 10 nm full-width half-maximum (Green) and 570 nm with 10 nm full-width half-maximum (Yellow).

PRI sensor spectral response graph.

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