Hukseflux Portable Solar Radiation Sensor, with read-out unit/datalogger - LP02-LI19

Figure 1 LI19 connected to LP02.

LP02 is a solar radiation sensor that can be applied for most common solar radiation observations. It complies with the latest ISO and WMO standards. The scientific name of this instrument is pyranometer.
The LI19 is a high accuracy hand-held read-out unit / datalogger. It can be used to make mobile measurements, for short term datalogging (as a static logger), and as an accurate millivolt amplifier directly connected to a PC.

A nice clear print of the original product brochure.

LP02 serves to measure the solar radiation flux that is incident on a plane surface in W/m2 from a 180 degrees field of view (also called ""global"" solar radiation). Working completely passive, using a thermopile sensor, LP02 generates a small output voltage proportional to this flux. Contrary to photodiode-based- and ""black and white"" instruments LP02 has a spectrally flat response across the full solar spectrum.

LI19 is used to display the measured flux level; for attaining that, the sensitivity of LP02 is entered into the LI19, by programming it using a PC. USB connection is part of the delivery. Software should be downloaded (this is to ensure that the latest version is applied).
The LI19 is battery powered, using 2 AA-type batteries. These are included in the delivery.
Batteries allow 50 days of operation.

The system is delivered in a handy carrying case, to make field measurements easy.

Operation:

  1. switch on LI19, connect LP02
  2. connect LI19 to PC, using USB connection box and LI19 software
  3. check sensor settings
  4. disconnect from PC
  5. optional: mark settings on LI19
  6. start measurement
  7. switch off LI19

Delivery

LP02 / LI19 / 2 spare batteries / software / transport casing / USB connection box.
