Metrology & Calibration Services

Verifying Measurement: Ensuring Accuracy

Dimensional inspection metrology servicesAt Laboratory Testing Inc., near Philadelphia, PA (USA), our Metrology Services cover both the Dimensional Inspection and Calibration Services performed in our metrology lab called LTI Metrology. These services are A2LA accredited to ISO 17025.

In its broadest sense, Metrology is the science of measurement and is concerned with standardization in measurement, calibration and inspection. During calibration service, the measurement values of tools and instruments are compared with a calibration standard of known accuracy. Dimensional inspection compares dimensions of product features with design specifications.

A Highly Qualified Metrology Lab

oven_surveyLTI Metrology is a highly qualified independent metrology laboratory that has provided fast, affordable and reliable dimensional inspection, measuring instrument calibration and on-site calibration services for nearly 30 years. All measurement results are NIST traceable, meaning they are tied to stated references of this national standard through an unbroken chain of comparisons. In addition, the traceability and uncertainty of measurements are validated through our accreditation process.

The responsive service and skilled technicians in the metrology lab also help make LTI a leader in so many areas. LTI employees know and understand this field, and they are dedicated to helping customers. The team of technicians has over 200 years of combined calibration experience.

For the most part, LTI Metrology specializes in industrial metrology services that are performed for B2B customers. Measuring tools, instruments and equipment used in production processes are calibrated to ensure the validity of measurement results. We also inspect our customers’ fasteners and other machined parts with high-tech equipment to ensure their dimensions conform with design specifications.
