The SMP3 is a smart pyranometer with low maintenance and industry standard digital and analogue amplified outputs. Based on the proven CMP 3 technology the SMP3 adds Modbus® interface, improved response time and temperature corrected measurement data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological stations easy.
The SMP is protected against over voltage, reversed polarity and short circuiting. Because all SMP’s have identical sensitivity and connections exchanging instruments during recalibration is easy.

PC Software for data logging, display of data and Modbus® address setting is standard provided.

SMP3 measures global solar radiation on a horizontal plane. When tilted with the same angle as a PV panel it measures the tilted global radiation, for PV module efficiency calculations.
