Field Services (on-site)

Pratt & Whitney strives to maintain the highest standards of quality and customer service. Our Sales Engineers and Product Specialists provide on-site field services, training and support in a timely and efficient manner. They also ensure that our calibrations and gage repairs meet original factory specifications. All calibrations meet the requirements of ISO17025 and most are accredited by the American Association for Laboratory Accreditation (A2LA/cert# 2629.01).

For factory services, please visit Pratt & Whitney Factory Services. A Return Material Authorization (RMA) is required in most cases for sending products to Pratt & Whitney for repair or calibration. Please read the Pratt & Whitney RMA Return Instructions for complete details.  ** See important Covid-19 statement below.


  1. For reoccurring calibrations, purchase orders should be submitted 60-90 days in advance of needed service. 
  2. We make every effort to couple multiple service calls within a geographic area.  Once dates are scheduled, any cancelation will add to further delays and is subject to requoting because of the added cost.
  3. Lead times are greater on orders requiring supplier portal submissions, background checks, safety questionnaires, and supplier forms.  Additional fees will apply.
  4. For GageCal software upgrades, customer is responsible for updating the computer and operating system to GageCal 7 System Requirements before Product Specialist arrival. 
  5. Expedited field service is quoted upon availability and request.
