The SMP 6 is a first class pyranometer that combines the sensor technology and housing from the CMP 6. The SMP 6 has both digital and analogue outputs, low maintenance, extremely robust and reliable and comes with 5 years warranty.
The SMP 6 has an internal desiccant that will last for at least 10 years. This minimizes maintenance significantly.
The interval for dome cleaning can be extended, and the quality of measurements maximized, by fitting SMP 6 with the CVF 4 ventilation unit.
The SMP 6 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 SMP 6, exchanging instruments for recalibration is easy.
SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting is provided as standard.
