MS-40S Smart Albedometer

Made with two MS-40S Pyranometers as well as a special albedo kit, the MS-40s features a glare screen to measure albedo and total reflectance. It is an ideal tool for solar power plants with bi-facial PV modules, as well as in meteorological applications.

With internal temperature, humidity and tilt sensors for remote diagnostics, this Smart Albedometer has everything needed to ensure proper installation and correct maintenance practices moving forward.

Features

  • ISO 9060:2018 Class C (Second class)
  • "Spectrally flat"
  • Quartz diffusor technology
  • ISO 17025 certified calibration
  • 5 year warranty and recommended recalibration
  • Smart interface: (MODBUS 485 RTU, SDI-12, 4-20mA, configurable 0-10mA / 0-1V with external optional 100? precision shunt resistor)
