You can look up the calibration data for most LI-COR instruments by selecting Calibration Certificates above the search bar and entering the serial number. You can also contact us to get the information.

30 µA / 100 klux.

Light sensors output a voltage or current signal, which can be read by the LI-250A, LI-1500, or many dataloggers.

To fix a dataset, simply divide by the incorrect multiplier and multiply by the correct multiplier.

0 to 25 mV, or 16-bit 0 to 100 mV.

This question is most often asked to determine whether the measurements being obtained are reliable and correct. In this case, one generally wants to know the “full-scale” response of their sensor, or what would be seen under the most ideal conditions. However, LI-COR light sensors can measure values far above the full-scale response, so the maximum value that can be obtained may not be a correct value to use when determining whether the measurements are reliable and correct.

The LI-210/R is a photometric sensor that has a linear response up to 100 klux. The full-scale value on a clear sunny day is approximately 25 klux. Direct sunlight measurements may be closer to 100 klux and cloud-edge effects can also occur in these measurements.

No. Some companies incorporate LI-COR pyranometers in their sun tracker devices, but LI-COR no longer makes one.
