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 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

Description

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.

SR05 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. SR05 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 SR05, the display will show the actual value of the solar radiation in W/m². Programming LI19 is done through its PC user interface.
