E. O. Habhegger, a licensed calibration service provider in New Jersey, Pennsylvania, and Delaware, specializes in fuel dispenser calibration with over 60 years of experience. Our expertise extends to various environments such as marinas, government-owned depots, airports, commercial businesses, truck stops, and retail fueling facilities.


We offer comprehensive calibration services ranging from single dispenser calibrations to bulk fuel oil plants. Our team understands the importance of maintaining accurate fuel dispensers and recommends regular calibration checks at least once a year, preferably twice a year, to prevent potential Weights & Measures violations. State or County's Weights & Measures officials hold the authority to condemn (shut down) fuel dispensers and impose fines for violations upon discovering faulty equipment.


Beyond compliance risks, malfunctioning meters and out-of-tolerance fuel dispensers can have other negative implications. By regularly calibrating your fuel dispensers, you can safeguard your profits by ensuring fuel is not being unnecessarily given away at the dispenser. Additionally, accurately calibrated dispensers facilitate the precise diagnosis of issues such as slow flow problems and the need for filter changes.
