Return Authorization Form


Thank you for choosing PTC® for your calibration needs.
Please fill out and submit the form below for a return materials authorization (RMA) number. PTC® will email you the RMA number and return shipping address. After receiving and evaluating your unit, we will contact you with a quote. Once the quote has been approved, PTC® will proceed with repair/recalibration. 

The calibration interval is determined by the end user, based on frequency of use, severity of conditions, environmental factors, and other variables. The calibration interval of 12 months will be used unless otherwise specified.
