The Smart pyranometer SMP 6 (ISO 9060:2018 - spectrally flat, class B specification - formerly ISO 9060:1990 first class) combines the sensor technology and housing from the CMP 6 in combination with a Smart interface. It has both digital and analogue outputs, low maintenance, is extremely robust and reliable and comes with 5 years warranty.
The integrated bubble level is raised to the top of the housing and can be viewed without removing the snap-on sun shield, which also covers the signal cable connector.
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, 0 - 1 V or 4 - 20 mA 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, can be downloaded from the Kipp & Zonen / Ott HydroMet webpage.
