SMP22 Pyranometer
The SMP22 is a spectrally flat Class A 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.
The SMP22 has internal desiccant that will last for at least 10 years. This minimizes maintenance significantly.
