Class A Thermopile Pyranometer
The SEVEN thermopile pyranometer 3S-TP-MB-A is designed to meet the ISO 9060:2018 (fast-response, spectrally flat, Class A) and IEC 61724-1:2021 Class A standards.
Equipped with cutting-edge thermopile detector and diffuser technology, this high-precision device features low zero-offset behavior and exceptional stability, ensuring highly accurate solar radiation measurements. This advanced technology makes it an ideal solution for meeting the highest standards in solar energy system performance monitoring.
The SEVEN pyranometer also includes a humidity sensor and two temperature sensors, enabling multi-parameter environmental monitoring. These additional features allow for precise adjustments and accurate readings under varying conditions.
The measured irradiance, humidity, and temperature data are transmitted to data loggers and other receiving units via a serial RS485 interface with the Modbus RTU protocol.
Additionally, SEVEN offers Class B and Class C pyranometers upon request.
