Vacuum Gauge Calibration Services in the Greater Philadelphia Area

Depressurized environments are necessary for many manufacturing and test processes. Vacuums create environments with controlled atmospheric conditions and are central to the operation of pumps in fluid systems. Malfunctioning or failing vacuums are serious process control defects, and regularly scheduled vacuum calibration ensures operations perform flawlessly.

The Vacuum Calibration Process

Computerized pressure modules with negative pressure capacities perform the inspection and record the results of vacuum calibration. Before the process begins, instruments are stressed to full capacity three times to be sure they are in working order. During the vacuum calibration process, a known standard sets each pressure point inspected and compared with the readings received from the calibrated instrument. The comparison identifies any deviation from the standard. Instruments typically receive a 5-point vacuum calibration with comparisons to the standard at every 20 percent capacity, but a higher accuracy calibration will include ten inspection points at every 10 percent capacity.

Our highly trained technicians are efficient and reliable when calibrating transducers, barometers, and vacuum gauges for absolute, atmospheric, and gauge pressure devices. As is typical with any measuring instrument, regular calibration will ensure repeatable accuracy by comparing the measurement produced by the instrument with that of standard or allowable tolerances. Adjustments are made to the instrument to bring the measurement within tolerance. Vacuum calibration customers receive a detailed Calibration Certificate for each item calibrated that lists “as received” data, complete calibration results, information about any adjustments or repairs made during calibration, and NIST traceability.

Keep Critical Systems Calibrated With LTI

Vacuum calibration is necessary to correct deviations in readings occurring over equipment lifespans as components age or tubing becomes contaminated. Poor or failing sealing can cause inaccuracy, and calibration efforts can correct drifting vacuum gauges while ruling them out as a source of system leakage. In addition to vacuums, LTI offers an extensive list of calibration and material testing services to assist manufacturers; whether in our state-of-the-art laboratory or on-site, our engineers and technicians provide world-class expertise for product approvals.

LTI has been a trusted partner with unmatched customer service, dependable deliveries, and excellent quality in mechanical and ultrasonic testing for many years. The entire team at LTI truly cares about their customers and I look forward to working with them for a long time.

LTI has provided excellent customer service throughout several projects, adjusting their standard practices to accommodate specific requests of the customer. The employees involved have been helpful and responsive, we appreciate the personalized service.

It was truly a pleasure to work with you and your team at LTI, and I will always cherish the friendship we have developed over the years. I can honestly say there has not been a single incident where LTI disappointed me.
