LP02 is a solar radiation sensor that is applied in most common solar radiation observations. LP02 complies with the second class specifications of the ISO 9060 standard and the WMO Guide. LI19 is a high accuracy handheld read-out unit / datalogger. The LP02-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 LP02, the display will show the actual value of the solar radiation in W/m².
LP02 measures the solar radiation received by a plane surface from a 180 ° field of view angle. This quantity, expressed in W/m², is called “hemispherical” solar radiation. LP02 pyranometer can be employed outdoors under the sun, as well as indoors with lamp-based solar simulators. Its orientation depends on the application and may be horizontal, tilted (for plane of array radiation) or inverted (for reflected radiation).
The system is supplied in a practical transport case, for easy transport and protection during field measurement campaigns. Also included are the necessary software, AA-type batteries and a USB cable. Fresh batteries allow for more than 50 days of operation. LI19 may also be used with other pyranometers and heat flux sensors.
LI19 displays the measured radiation and stores measured data. Once programmed with the sensitivity of LP02, the display will show the actual value of the solar radiation in W/m². Programming LI19 is done through its PC user interface.
