Apogee Instruments recommends recalibrating all sensors every two years. You may wish to wait longer between recalibration cycles depending on your particular requirements. To determine if recalibration is necessary for pyranometers and quantum sensors, visit our information on the Clear Sky Calculator. For information on Apogee's secondary standard, first class, and second class thermopile pyranometer calibration services, please visit thermopile pyranometer calibration services.
To send your sensor in for recalibration/repair, please fill out the RMA Form with your request. Or, email technical support with your request, include the model and serial number(s) with a brief description of your request. For broken sensors, describe the nature of the malfunction.
*Model and serial numbers are found on a white label on sensor cables, the back-side of meters, or the underside or back of spectroradiometers.
Once you’ve been issued an RMA number please make attention to that number on the outside of the package and ship to:
721 W 1800 N
Logan, UT 84321, USA
Please do not send any products back to Apogee Instruments until you have received a Return Merchandise Authorization (RMA) number from our tech support department.
Send all RMA sensors and meters back in their original, unmodified condition:
- clean the sensor’s exterior and cord
- do not modify the sensors or wires, including splicing, cutting wire leads, etc.
- if a connector has been attached to the cable end, please include the mating connector – otherwise the sensor connector will be removed in order to complete the repair/recalibration
Failure to do the aforementioned may result in an additional service/repair fee prior to calibration. For questions, contact Technical Support.
