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. And, 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 leveling 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.
