Reliable net radiation measurements in real time
If you're planning a large sensor network and want long-lasting
performance for less work and less budget, then the SN-500 Net
Radiation Sensor is perfect for you. Get research-grade accuracy
for much less than other four-component net radiometers. Also, it's
plug and play with the ZL6 data logger and ZENTRA Cloud for easy,
remote data access, so you can visualize your data in near-real
time, wherever you are.
Engineered for excellence
Net radiation is a key variable in surface energy balance and
influences turbulent fluxes, including evapotranspiration. The
Apogee SN-500 four-component net radiometer consists of blackbody
pyranometer and pyrgeometer pairs that face both upward and
downward to provide incoming and outgoing shortwave and longwave
radiation measurements. Each individual sensor measures the four
separate components of net radiation for best accuracy.
Simple and precise
A small, lightweight design means easy mounting to a cross arm
using a mounting bracket (included) which simplifies precision
levelling of the sensors.
Easy remote data access
Combine the SN-500 with the ZL6, where all data is connected and
delivered in near-real time through the cloud. And with the
SN-500's four-component measurements, it's a snap to compute any
number of important radiation parameters like net radiation, net
longwave radiation, net shortwave radiation, albedo, total
irradiance, etc.
Affordable accuracy, guaranteed
Backed by an industry-leading four-year warranty and outstanding
customer support, the Apogee SN-500 is a long-life, accurate,
easy-to-install net radiometer with an ultra-rugged form and remote
data access. If you need research-grade accuracy at an affordable
price, then you'll love the easy-to-use Apogee SN-500 Net Radiation
Sensor.
