RMA System

Welcome to our RMA System for your service, repair and calibration submissions. You can manage your orders by creating an account online and completing the RMA Form for any equipment sent in for service. View 'What to Expect' for more details on the entire ordering process.


Select your equipment from the links below, then complete the RMA form. If you don't see your make and model listed on our site, please call us at 727-584-5063 and we will add it. Our RMA shows the pricing for different types of calibration, including expedite fees.

Once you submit your RMA form, print out the email you receive and include that Order Summary printout with your shipment. If the response back with your order number states that payment for your order is required or pending, please ignore it! We will bill you after our calibration services are completed, and you’ve received your accredited NIST or A2LA calibration RMA. Return shipping will be calculated when the equipment is returned to you.
