SR05-LI19 Pyranometer

SR05-LI19

Pyranometer with handheld read-out unit / datalogger

SR05 is a solar radiation sensor that is applied in most common solar radiation observations. Model version SR05-A1 complies with the spectrally flat Class C specifications of the ISO 9060 standard, and offers analogue millivolt output. LI19 is a high accuracy handheld read-out unit / datalogger. The SR05-LI19 combination is well suited for mobile measurements and short term datalogging. LI19 displays the measured radiation and stores measured data. Once programmed with the sensitivity of SR05, the display will show the actual value of the solar radiation in W/m².

The SR05 measures the solar radiation received by a flat surface from a viewing angle of 180°. This quantity, expressed in W/m², is called “hemispherical” solar radiation. The SR05 pyranometer can be used outdoors in the sun, as well as indoors with lamp-based solar simulators. Its orientation depends on the application and can be horizontal, tilted (for radiation in the plane of the array) or inverted (for reflected radiation).

The system is supplied in a practical carrying case, for easy transport and protection during field measurement campaigns. The necessary software, AA batteries and a USB cable are also included. Fresh batteries allow more than 50 days of operation. The LI19 can also be used with other pyranometers and heat flow sensors.

The LI19 displays the measured radiation and stores the measured data. Once programmed with the sensitivity of the SR05, the display will show the actual value of solar radiation in W/m². Programming of the LI19 is done through its PC user interface.

Suggested use
Short-term field measurement of solar radiation
