Differential pressure gauges are required to be tested for accuracy when purchased and annually thereafter by most local jurisdictions. This service is provided by Bac-Flo Unlimited which verifies gauge accuracy to plus or minus .2 psid in accordance with N.I.S.T. national standards. Upon precise verification a detailed certification report is provided in reference to the gauge serial number and testing company. The fee for each gauge certification is $60.00. Shipping address for gauges: Bac-Flo Unlimited, Inc., 215 West Bandera Road, Suite 114-455, Boerne, TX 78006. Include $20 for return shipping along with company address and phone number. There is usually a two to three day turn around time for getting it shipped back to you.
Our gauge testing/certification service is performed only by Troy Baird. He is Bac-Flo Unlimited's employee with over 16 years experience in testing and certifying gauges. If there are any concerns about your gauge Troy will be personally contacting you. For additional information about gauge certifications feel free to contact us by phone or email.
