Metrology & Calibration Services

Verifying Measurement: Ensuring Accuracy

Temperature calibration laboratoryLTI Metrology, the metrology services and calibration laboratory near Philadelphia PA provides accurate and affordable NIST traceable (National Institute of Standards and Technology) and A2LA accredited dimensional inspection, on-site calibration and instrument calibration services.

The metrology lab offers calibration services for measuring hand tools, gages, standards and pressure, torque, force, temperature, electrical, mass, vacuum and flow instruments. Repair service is also available for many items, as well as on-site calibration services for measuring tools and a variety of equipment. The metrology lab technicians also verify the dimensional accuracy of product features for customers with dimensional inspection services.

During instrument calibration, technicians compare the performance output of a measuring tool or instrument with a measurement standard. Calibration services confirm that the item will produce results which meet or exceed that standard’s criteria. Our professional calibration staff works with state-of-the-art calibration equipment in an environment-controlled laboratory, so you can count on precise results and timely turnaround.

On-site calibration servicesCustomers receive a detailed Certificate of Calibration for each item receiving calibration services. The Certificate lists “as found” and “as left” conditions, our NIST-traceable standards, complete calibration results and any adjustments or repairs made at our calibration laboratory. Pick-up and delivery services are offered for customers within 60 miles of our Hatfield, PA metrology lab, at no additional charge.
