SMP12 Fast Response Smart Pyranometer

Quick Overview

The new SMP12 is an industry's first fast response spectrally flat Class A Pyranometer that combines solid-state dome heating to mitigate the effects of morning dew, frost or snow. The SMP12 combines proven sensor and diffuser technology from the RaZON+ PH1 and PR1 radiometers with an enhanced version of the Smart interface and the low maintenance of the SMP10. The SMP12 has an internal drying cartridge that will last for at least 10 years if the housing is not opened. This further reduces maintenance significantly. The RS485 Modbus RTU outputs provide an output for solar irradiance (-200 to 2000W/m²), Internal humidity and temperature, plus tilt angle.

Details

The SMP12 is a high quality pyranometer designed for measuring solar irradiance on a plane surface (radiant flux, W/m²), which results from combination of the direct solar radiation and the diffuse sky radiation. The measurement can be made horizontally for Global Horizontal Irradiance (GHI) or tilted for Global Tilted Irradiance (GTI). The SMP12 instrument is designed to measure and report solar irradiance, sensor body temperature, internal humidity and tilt angle from horizontal. The SMP12 can also be used to create an albedometer to measure surface reflectance where one SMP12 is facing the ground and another SMP12 is facing the sky.

All SMP's have the RS485 Modbus RTU interface, very low power requirements and are supplied with comprehensive, traceable, calibration certificates. Calibrations are traceable to the World Radiometric Reference (WRR) in Davos Switzerland and are performed in accordance with ISO 9847, Annex A.3 'Calibration of Field Pyranometers by comparison to a Reference Pyranometer'.s and are supplied with comprehensive, traceable, calibration certificates.
