ELSNER 70157 KNX PY Pyranometer

The KNX PY Pyranometer, produced by ELSNER, is a device specialized in measuring global radiation, perceived as heat. This instrument measures the current global irradiance expressed in watts per square meter (W/m²), allowing us to deduce the amount of energy incident on a surface over a defined period of time, expressed in kilowatt hours per square meter (kWh/m²).
