ISO 9060 spectrally flat Class A No change of desiccant for 10 years Smart, more than just digital RS-485 Modbus® communication 5 year warranty SMP10 Pyranometer The SMP10 is a spectrally flat Class A pyranometer that combines the sensor technology from the CMP 11, the Smart interface from the SMP11 and the low maintenance from the CMP10. The SMP10 has an internal drying cartridge that will last for at least 10 years if the housing is not opened. This minimizes maintenance significantly. The interval for dome cleaning can be extended, and the quality of measurements maximized, by fitting SMP10 with the CVF4 ventilation unit. The SMP10 has Modbus® interface, amplified analogue output, improved response time and temperature corrected measurement data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological and solar energy stations easy. The SMP10 is protected against over voltage, reversed polarity and short circuiting. Thanks to the standardized output and connections of every SMP10, exchanging instruments for recalibration is easy. SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting is provided as standard.
