SMP22 is a secondary standard total radiation meter that combines a new intelligent interface with CMP22's quartz dome and sensor technology. After decades of performance testing, it has become the most accurate and reliable total radiation meter in the world. SMP22 has the widest spectral range, faster directional response time, and reduces thermal offset errors. Using the best optical quality circular cover, the directional error is reduced to below 5W/m2. SMP22 has RS-485 Modbus ® Standard interface, 5-year warranty. （*）
SMP22 is equipped with a desiccant that can be used continuously for at least 10 years, significantly reducing maintenance workload. If the SMP22 is equipped with a CVF4 ventilation device, the time interval for cleaning the circular cover can be extended and the measurement quality can be optimized. SMP22 is equipped with a digital interface, and the analog output signal is amplified and processed. The response time has also been improved, and the measurement data is individually temperature corrected. It comes with cosine response data measured one by one, with a wide power range and low supply voltage between 5-30VDC, making it easy to integrate with meteorological stations and solar power plants. The design of SMP22 is extremely sturdy and reliable, with a 5-year warranty. Due to the standardized output and connectors used in each SMP22, you can easily exchange instruments for recalibration. The standard components provided include SmartExplorer Windows for recording data ™ Software, data display screen, and Modbus ® Address setting module.
