Radiometer & Thermometer Calibrations

The SOLAR EYE irradiance control system on board QUV and Q-SUN testers needs to be calibrated by the user periodically.  This ensures accurate and consistent results.  The CR10 and CR20 radiometers are used in this calibration process, and it is fast and easy for the user.

It is also important that the CR10 and CR20 radiometers themselves be returned to Q-Lab once per year for a recalibration. See LW-6008 - Recalibration Return Procedure.  Radiometer recalibrations are inexpensive and fast, and can be performed at any one of our convenient, global recalibration centers.  These are shown below.

Additionally, the CT202 calibration thermometer used to in all Q-SUN model testers should also be recalibrated once per year.  The same global recalibration centers below may be used.

All other temperature sensors in the QUV tester and temperature/relative humidity sensors in the Q-SUN family of testers are calibrated through off-the-shelf standard reference thermometers, or are designed to be replaced annually.

Common part numbers for recalibration are shown below:

  • CR10/RECAL - Recalibration of CR10 Radiometer
  • CR20/RECAL - Recalibration of CR20 Radiometer
  • CT202/RECAL - Recalibration of CT202 Reference Thermometer

For more information about calibrating the sensors on board the QUV and Q-SUN testers, or for calibrating the calibration devices themselves, please visit our Thermometer & Radiometer product pages.

Calibrating your reference thermometers and radiometers is important to achieving consistent and accurate weathering test results. When was the last time your reference devices were calibrated? Contact us now for a quote.
