The pyranometers LPPYRA13 measure the irradiance on a flat surface (W/m²).
The pyranometers are equipped with an adjustable shadow ring for the measurement of diffuse radiation only.
They are classified as Spectrally Flat Class A in accordance with ISO 9060:2018 (previuosly ‘Secondary Standard’) and according to the publication “Guide to Meteorological Instruments and Methods of Observation” of WMO.
The pyranometers are available in five versions:
- LPPYRA13 – PASSIVE
- LPPYRA13AC – ACTIVE with CURRENT 4..20 mA output
- LPYRA13AV – ACTIVE with VOLTAGE 0..1 V, 0..5 V or 0..10 V output
- LPPYRA13S – with MODBUS RS485 output
- LPPYRA13S12 – with SDI-12 output
