Apogee Instruments’ new four-component net radiometer provides individual measurement of net radiation components. The sensor features an SDI-12 output, eliminating the need for multiple analog channels to measure the individual components of net radiation. The net radiometer comes as a complete package that includes net radiometer, mounting rod, pigtail lead cable for datalogger interface, and carrying case.
Onboard A/D Conversion and SDI-12 Output
Apogee net radiometers feature onboard A/D conversion and SDI-12 output to eliminate the requirement of multiple analog datalogger channels.
Four-component Net Radiometer
An upward-looking and downward-looking pyranometer, and an upward-looking and downward-looking pyrgeometer provide separate measurements of the four components of net radiation.
Individually Heated Radiometers
Each radiometer includes an individual heater to increase accuracy by minimizing the influence of dew/frost on the filter.
Compact and Light Weight
Designed to be light weight and small in size to facilitate easy mounting.
- Net radiation is a key variable in the surface energy balance and influences turbulent fluxes, including evapotranspiration.
- It include measurements on flux towers and weather stations.
- An on-board 24-bit analog to digital converter makes measurements and provides a digital SDI-12 (SN-500) or Modbus (SN-522) output.
- This eliminates the need for multiple analog datalogger channels to measure each of the four components of net radiation.
- Measure all four components of net radiation with a digital output that saves datalogger channels.
- Comparable accuracy to industry leading competition in long-term field testing.
- The small lightweight design enables easy mounting to a cross arm using the AM-500 mounting bracket that facilitates precision leveling.
- Each sensor includes a 0.2 W heater to minimize errors from dew, frost, rain, and snow that can block the radiation path.
