User's Manual Datasheet
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 system is supplied in a practical transport case, for easy transport and protection during field measurement campaigns.LI19 may also be used with other pyranometers and heat flux sensors
Operation of SR05-LI19 is easy
Short-term field measurement of solar radiation
Education in solar energy
Building physics / insulation, thermal comfort and energy budget measurement
Meteorology / surface energy flux measurement
Solar energy / PV system performance monitoring
