SN-500 Net Radiation Sensor
Compact design and easy installation make it a cost-effective sensor.
Product details
Product Introduction:
The SN-500 net radiation sensor produced by Apogee in the United States has a built-in A/D conversion module and an output signal type of SDI-12. It is compact in design and easy to install, making it a cost-effective sensor.
Typical applications:
Research on plant photosynthesis, plant growth, and the thermal balance of energy such as soil transpiration, water surface temperature, and evaporation.
Product features:
Ø High precision: Built in A/D conversion module, SDI12 digital output, saving channels for the collector.
Ø Heating sensors: Each sensor contains a 0.2 W heater to reduce errors that may obstruct the radiation path caused by dew, frost, rain, and snow.
Ø Case: Snow avalanche prediction by Alaska Electric Light&Power
Ø Lightweight and compact in size
