SSR11 Pyranometer ISO First Class
 The SSR11 pyranometer is suitable for measuring global short-wave solar irradiance incidenting a plane surface, offering a full 180° field of
view (FOV). Capable of measuring up to two suns, 2000 W/m2, the SSR11 is also well suited for higher intensity indoors artificial lamp
measurement applications. Employing entirely passive thermopile-based sensing technology, the SSR11 generates a low level DC millivolt output
signal proportional to the solar short-wave flux received at the detector surface. The instrument design serves to reduce the possibility of
wind related signal noise and thermal offset related error effects by employing a set (two) of precision ground and polished glass domes,
resulting in improved measurement accuracy. Determining short-wave solar irradiance requires connection to either a data logger or digital
voltmeter with a measurement resolution of ten micro-volts or better; simply divide the SSR11 millivolt output signal by the factory supplied
calibration factor to arrive at irradiance in W/m2 units. Typical SSR11 measurement applications include scientific meteorological observations,
building physics, climate and solar collector/PV panel efficiency testing. For conventional horizontal plane mounting applications requiring
accurate leveling, the SSR11 is equipped standard with adjustable leveling feet and a bulls-eye bubble level. The SSR11 signal cable can be
easily installed and replaced by the user, thus minimizing down-time and expense otherwise associated with instrument re-cabling by the
manufacturer.
