The LPPYRA03 are high-quality pyranometers that are classified as Spectrally Flat Class C (Second Class) in accordance with ISO 9060:2018 and according to the WMO. These pyranometers are designed to measure the irradiance on a flat surface (W/m²) and are ideal for a variety of applications, including solar energy research and meteorology.

The LPPYRA03 is available in different versions to meet your needs. The LPPYRA03 passive version is perfect for direct tilted installation, while the LPPYRA03AC active version comes with current 4..20 mA output. This version allows easy connection with any analog measuring system and the output can be read with standard device. The LPPYRA03ACS version includes a double 4…20 mA current output and RS485 serial output with MODBUS-RTU protocol. This version allows easy connection with any digital measuring system and the output can be read with MODBUS-RTU protocol. The LPPYRA03AV version has an active with voltage 0..1 V, 0..5 V, 0..10 V output, to specify. This version allows easy connection with any analog measuring system and the output can be read with standard device. The LPPYRA03S version has a MODBUS RS485 output. This version allows easy connection with any digital measuring system and the output can be read with MODBUS-RTU protocol. And the LPPYRA03S12 version has SDI-12 output. This version allows easy connection with any digital measuring system and the output can be read with SDI-12 protocol.

All of these versions are easy to set up and install, and come with an adapter to ease the mounting process. The LPPYRA03 also features an optional fixing base that integrates a leveling device, making it easy to ensure that the pyranometer is level, even on uneven surfaces. This feature, combined with its small size, makes it the perfect solution for small-scale PV monitoring and efficiency control of PV systems.

In addition, the LPPYRA03 has been designed to withstand harsh weather conditions and extreme temperatures, making it a durable and reliable tool for professionals in the field. With its high precision and reliability, the LPPYRA03 is an ideal tool for solar energy research, meteorology and other related fields. The pyranometer can be calibrated with the international standards defined by ISO9847. And it also comes with a measurement report that validates the directional response and temperature dependency of the sensor.
