Recalibration and Repairs
As a best practice, Apogee Instruments recommends recalibrating all pyranometers, quantum sensors, infrared radiometers, net radiometers, spectroradiometers and our other 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, you can visit our ClearSky Calculator tool or download the App for iOS or Android. The ClearSky Calculator indicates what your outdoor readings should be as a reference for comparison. Apogee can also calibrate several thermopile pyranometers from other companies. For information on Apogee's Class A, Class B, and Class C thermopile pyranometer calibration services, please visit thermopile pyranometer calibration services.
To send your sensor in for recalibration or repair, please fill out the RMA Form with your request or email technical support with questions or your request. Please 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 for Apogee sensors are often found on a white label on the sensor cable, on a small sticker on the bottom of the sensor, on 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:
Apogee Instruments
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.
