Description
Fast response and precise measurements for IEC61724-1 compliance
The LPR10 is a fast response pyranometer designed to provide precise measurements of global solar radiation even under the most demanding conditions. The instrument complies with IEC61724-1 requirements for class A photovoltaic (PV) monitoring systems and also meets the guidelines established by the World Meteorological Organization (WMO).
Advanced diagnostic features
The LPR10 continuously monitors its internal temperature, humidity and pressure to ensure optimal operating conditions and anticipate maintenance needs. In addition, it includes an internal heater to prevent dew and frost formation on the glass dome. The instrument features a RS-485 serial port with MODBUS-RTU protocol, facilitating its integration into meteorological stations and solar monitoring systems.
