Service & Support

Your work is important, so down time is a disaster. We do all we can to be sure your instrument keeps running “like new”. Our service and support departments are here to help you get through difficulties.

  • Technical support
  • Extended warranty (with purchase)
  • Service contracts

Our reputation for supporting your purchase is unmatched

You are making an investment in top-notch, leading-edge technology, and we know you expect to rely on it for years to come. Don’t get caught with an instrument you can’t keep running because the maker stops supporting it.

4D is dedicated to keeping our equipment up to date and operating at high effectiveness. We’re still supporting instruments we shipped nearly 20 years ago. Check out our warranties and extended service plans with these links:
