ISO 9060 pyranometer SMP12

first classModbusRS-485

- ISO 9060 spectrally flat fast response Class A and IEC 61724-1 Class A monitoring - Industry-first Class A integrated dome heating with no moving parts preventing dew & frost - Enhanced surge protection & remote tilt angle and internal humidity monitoring - RS-485 Modbus® communication - 5-year warranty The new SMP12 is industry's first fast response spectrally flat Class A pyranometer that combines solid-state dome heating, with no moving parts, and best-in-class surge protection to maximize accuracy and minimize maintenance. The SMP12 combines proven sensor and diffuser technology from the RaZON+ PH1 and PR1 radiometers with an enhanced version of the Smart interface and the low maintenance of the SMP10. The SMP12 has an internal drying cartridge that will last for at least 10 years if the housing is not opened. This further reduces maintenance significantly. Additional features based on customer feed-back are: - Tilt sensor to enable remote checks of whether the pyranometer mounting alignment has been disturbed. - Internal humidity monitor to provide confidence that the sealing has not been compromised, for example by an accidental impact.
