Effective May 8, 2015 Coastal Instruments will be closing our Gilbert, AZ facility which has been in operation since 1993. We plan to continue to supply the same level of support to the customers who have been using our AZ office from our existing facilities in Burgaw, NC and Newberg, OR. If you are an existing customer of the AZ facility and are not sure where you should send your mass flow controllers for repair, give us a call at 1-800-632-4357 and our customer service folks will be glad to help you.
