Authorization (RMA) number from our technical support department by submitting an online RMA form at 

www.apogeeinstruments.com/tech-support-recalibration-repairs/

We will use your RMA number for tracking of the 

service item. Call (435) 245-8012 or email [email protected] with questions.

 

2. For warranty evaluations, send all RMA sensors and meters back in the following 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. 

Note:

 

When sending back sensors for routine calibration that have Apogee’s standard 

stainless-steel connectors, you only need to send the sensor with the 30 cm section of cable and one-half of the 
connector. We have mating connectors at our factory that can be used for calibrating the sensor.

   

3. Please write the RMA number on the outside of the shipping container.  

4. Return the item with freight pre-paid and fully insured to our factory address shown below. We are not responsible for
