Superior Service and Technical Support

AP is dedicated to providing world-class support extending beyond the technical operation of our equipment.

Our Service Department can help with calibration, repair or other hardware issues.

AP is proud to offer free tech support for the life of all our instruments. Our Knowledge Base is the first stop for technical questions, but if you'd prefer to talk to an expert one-to-one, AP’s application engineers will work with you to define your test procedure, troubleshoot your setup, and understand your results. Custom LabVIEW and API programming support is also available.

Help is available from Monday to Friday, 9am to 5pm (PST).
