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:

  • UC10/UV, /CW – QUV Irradiance Smart Sensor
  • UC20/340, /420, /TUV, /LUX – Q-SUN Irradiance Smart Sensors
  • UC202/BP, /IBP – Q-SUN Temperature Smart Sensors
  • UC10/RECAL – Recalibration and Return of UC10 Irradiance Smart Sensor
