Continuously monitor NDVI or PRI
*At METER, we think you should spend less time on complexity and
more time doing what matters.* *Apogee NDVI and PRI sensors are
easy-to-use.* And the best part? They're pre-configured for use
with the ZENTRA system, so you're instantly up and running.
Low cost-low maintenance
By focusing on just two relevant bands, it's possible to make an
accurate multiband radiometer for a fraction of what a
full-spectrum spectroradiometer costs. Apogee NDVI/PRI sensors are
multiband radiometers that combine an ultra-rugged form with
sophisticated cloud data delivery for an unbeatable
price-to-performance ratio. They're inexpensive enough to deploy
multiple sensors simultaneously, so you can maximize spatial
coverage and explore spatial and temporal variability in canopy
structure and function.
Deploy for months or even years
Most spectrometers are delicate and expensive, making long-term
field deployment risky. Apogee NDVI and PRI sensors are built for
long-term exposure to the elements. Encased in a durable housing
with an epoxy fill, they are watertight, weatherproof, and have
fully sealed optics.
Mount them on a fence post, tripod, or a meteorological tower.
They're rugged enough to leave in the field for an entire growing
season or longer.
Field ready and radiometrically calibrated
Each sensor is radiometrically calibrated to a NIST-traceable
standard. Readings are output in units of radiant flux
density. Calibration information is stored on board the sensor, so
you never have to worry about keeping track of calibration
coefficients.
Collect data and monitor remotely
To simplify your workflow, Apogee NDVI and PRI sensors are
plug-and-play with the ZL6 Data-logger, which means automatic
sensor recognition and zero programming. ZENTRA Cloud lets you
monitor remote sites in near-real time from any internet-connected
device. Observe field conditions, check and configure sensor and
system function, or download data from the comfort of your home or
office.
Work less. Measure more.
Apogee NDVI/PRI sensors are part of a complete system of
affordable, easy-to-use sensors, loggers, and software that require
little maintenance and put near-real-time data at your fingertips,
so you can publish more and work less.
