Litemeter Current PRO: Sun radiation sensor

Litemeter LM1-420 PRO is an analog photovoltaic pyranometer  equipped with a monocrystalline silicon cell. 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. The 4-20mA current loop output allows to obtain reliability and a high rejection to signal noise. This guarantees quality signal even at long distances (30m and more) also in areas with many electromagnetic disturbances like industrial areas and photovoltaic systems greater than 100 Kw.  The solar irradiance signal is temperature compensated; in this way  the solar irradiance values are independent by cell temperature.

The device is calibrated with our Primary Reference cell calibrated periodically by Fraunhofer Institute (DE), accredited by Dakks.
