SMP3

The SMP3 is a smart pyranometer with low maintenance and industry standard digital and analogue amplified outputs. 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.

Key Features:

  • ISO 9060 spectrally flat Class C 
  • 0 to 1 Volt or 4 to 20 mA analogue output
  • No change of desiccant for 10 years
  • Active temperature correction from -40°C to +80°C
  • 5 year warranty
