The SMP6 is a Spectrally Flat Class B pyranometer that combines the sensor technology and housing from the CMP6. The SMP6 has both digital and analogue outputs and is low maintenance, extremely robust and reliable. It also comes with 5 years warranty (*). The SMP6 has an internal desiccant that will last for at least 10 years, which minimizes maintenance significantly. The interval for dome cleaning can be extended, and the quality of measurements maximized, by fitting SMP6 with the CVF4 ventilation unit. The SMP6 has a RS-485 Modbus® RTU 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. Thanks to standardized output and connections of every SMP6, exchanging instruments for recalibration is easy. SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting is provided as standard.
