In the event that a unit is damaged or otherwise not performing as specified, repair and maintenance service is available. Warranty repair will be performed within one year from the date of purchase at no charge. Beyond one year, charges for time, material, and shipping/handling will be incurred. Warranty repair includes defects in material and workmanship only. Accidental damage or abuse repairs will always incur time, material, and shipping/handling charges. Shipping charges to the factory are the responsibility of the customer. Return shipping charges are also the responsibility of the customer (except for "in warranty" repairs).


If you need to return equipment, please contact us or email and indicate REPAIR REQUEST in the subject line. To obtain a RMA number, you will first need to provide the following information:

-Your name, email address, telephone number, ship-to address, and bill-to address
-Model of instrument you have
-Version of software that you have loaded if applicable
-Serial number of the instrument
-Detailed description of the issue

The RMA number should be referenced on the outside of the shipping box and on all correspondence relating to that particular shipment. Please include details of the service requested. Ensure that the equipment is securely packed with proper cushioning material on all sides. The unit should be insured for its full value in case of damage or loss in transit. After the repair is completed, we will contact you for payment. If payment is not received within 60 days after contact is made, then the repaired equipment will become the property of Applied Instruments.

Replacement/Spare Parts

Only parts that meet or exceed the original specification are used for maintenance and repairs. Hard copy operation manuals are also available at a nominal cost. Visit the Replacement Parts and Accessories page of our website. Soft copies (.pdf format) of the operation manuals are available for download at no charge from each product page on our website.

Version Updating And Channel Plan Additions

As our product lines are refined and features and performance are enhanced, we will upgrade older units at a nominal cost, plus shipping charges. Contact us or email for price and schedule if you are interested in having a unit updated.


Periodic calibration may be necessary to ensure that the unit is operating within the original factory specifications. A standard calibration charge will be incurred.
