Product Description
LP02 is a solar radiation sensor that can be applied for most common solar radiation observations. The scientific name of this instrument is pyranometer. LP02 pyranometer complies with the ISO 9060 second class specifications and the WMO guide. LI19 is a high accuracy hand-held read-out unit / datalogger. The portable LP02 – LI19 combination is well suited for mobile measurements and short term datalogging.
LP02 measures the solar radiation received by a plane surface from a 180o 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).
LI19 is used to display the measured radiation and for datalogging. Once programmed with the sensitivity of LP02, the display will read the actual value of the solar radiation in W/m2. Programming LI19 is done through its PC interface.
The system is delivered in a practical transport case, for easy transport and protection during field measurement campaigns. The case also includes the necessary software, AA-type batteries and a USB cable. Batteries allow for approximately 50 days of operation. LI19 may also be used with other pyranometers and heat flux sensors.
