The usual turnaround time is 2-3 business days for getting your gauge shipped back to you. Please note a delay in return shipping could occur without payment or the required information above. For maximum shipping protection, most ship their gauge in its hard sided case placed in a cardboard box. Removing heavy objects such as tools and fittings will reduce shipping costs. Gauge hoses do not need to be included.       

Upon receiving your gauge, we'll inspect, pressure test, verify accuracy points, and fully certify it with an updated certification report valid for a full year. If there are questions or concerns in regard to the gauge needing additional attention such as calibration or repair, you'll be immediately contacted to discuss.  

Our gauge testing and certification department is operated by Troy Baird. He has over 20 years experience in testing, certifying, and if necessary ensuring a quality, factory authorized repair of your gauge. If there are any questions or concerns after receiving your shipment Troy will be personally contacting you.  

Differential pressure gauges are required to be tested for accuracy when purchased and annually thereafter by most jurisdictions. This service verifies gauge accuracy to plus or minus .2 psid in accordance with NIST national standards. Upon instrument verification a detailed certification report is completed in reference to the gauge serial number and testing company, and provided to you. For additional information about getting your differential pressure gauge certified, feel free to contact us by phone or email.
