Litemeter Voltage PRO: Sun radiation and temperature sensor
Litemeter LM1-10V PRO is an analog photovoltaic pyranometer with a monocrystalline silicon cell laminated in performing glass. Manufacturing and Calibrations are done following the IEC 61215, IEC 60904-2; 60904-4; 60904-10 regulations.
The Silicon photovoltaic cell is laminated with E.V.A. and a performing antireflective glass for photovoltaic modules.
It guarantees the maximum precision in the measurement of irradiance and provides a measurement of the indicative temperature of the photovoltaic modules next to it.
The sensor has two signal outputs in voltage: one for solar irradiance and one for temperature. The solar irradiance signal is temperature compensated; in this way the solar irradiance values are independent by cell temperature.
All Litemeters are calibrated with our Primary Reference cell calibrated periodically by Fraunhofer Institute (DE), accredited by Dakks.
