SMP22 Pyranometer

The SMP22 is a secondary standard pyranometer that combines the new smart interface with quartz domes and sensor technology from the CMP22. Which has a proven track record of decades, making it the most accurate and reliable pyranometer in the world. The SMP22 has the widest spectral range, improved directional response, and reduced thermal offsets. Because of the highest optical quality domes the directional error is reduced below 5 W/m2. The SMP22 comes standard with RS-485 Modbus® interface and 5 year warranty.

The SMP22 has 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 SMP22 with the CVF4 ventilation unit.

The SMP22 has a digital interface, amplified analogue output, improved response time and individual  temperature corrected measurement data. The SMP22 is supplied with individual measured cosine response data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological and solar energy stations easy. The SMP22 is extreme robust and comes with 5 years warranty.

Thanks to standardized output and connections of every SMP22, exchanging instruments for recalibration is easy. 

SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting is provided as standard.

FAQ

  • What type of pyranometer can I use for my fixed PV panels farm?
    • For this application the CMP10 and SMP10 are advised as they have an internal drying cartridge that will last for at least 10 years.

      Please note that the pyranometer needs to be mounted in the same angle (POA) as the PV panel. 

       

      For users that prefer the desiccant visible Kipp & Zonen offers the CMP11 and SMP11 with visible and user changeable desiccant.
