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.
