SR20-D2-L Digital Class A Pyranometer

概要

The SR20-D2, manufactured by Hukseflux Thermal Sensors, is an ISO 9060:2018 spectrally flat Class A (secondary standard) digital pyranometer that measures solar short-wave radiation in a full hemisphere of the sky. It connects directly to a Campbell Scientific data logger and is designed for Modbus RTU applications that require high measurement accuracy in demanding applications such as scientific meteorological observation networks and utility scale solar-energy-power production sites.

利点と特徴

  • Low temperature dependence
  • Onboard digital temperature sensor
  • Ultra robust connector, desiccant holder, and sun screen
  • Temperature dependence characterized and supplied for each instrument
  • Directional response tested on each instrument
  • Digital output (Modbus RTU)
