It’s Pyranometer Calibration Season

It’s Pyranometer Calibration Season

LI-COR encourages our customers to return their LI-200/R Pyranometer Sensors for recalibration (suggested every 2 years after field deployment) between the months of March and September. Why? Because pyranometer sensors need to be calibrated outdoors in natural sunlight in order to construct an accurate relationship between the output of each sensor and incoming solar radiation. During LI-COR’s 40+ years of manufacturing and calibrating pyranometers, we have found that best results are obtained during the summer months when sensors can be…

LI-200R Pyranometer Performs Well in NREL Solar Radiation Assessment Tests

LI-200R Pyranometer Performs Well in NREL Solar Radiation Assessment Tests

Prior to the official product launch, LI-COR provided the National Renewable Energy Laboratory (NREL) with a set of LI-200R Pyranometers for their long-term solar radiation measurement project. The LI-200R is based on the proven LI-200 Pyranometer, but with a more robust cable and an improved seal against water vapor. The sensor is also detachable from the base/cable, simplifying installation and removal. Click here for a detailed comparison between the old and new sensor designs. 

NREL is a US government…

How to Prevent Negative Readings with LI-COR Light Sensors

How to Prevent Negative Readings with LI-COR Light Sensors

This tech tip helps to prevent mistakes that result in negative readings. When getting negative readings from your light sensor, check your multiplier, the connection between your light sensor and recorder/data logger, or the cable connection.

1. Did you enter the standard multiplier with a negative sign?

The Calibration Multiplier is always a negative number, because the shield of the coaxial cable of the sensor carries the positive signal instead of the negative signal. If you reverse the sign…
