Don’t Guess: Accurate Instruments Do the Job Correctly

Electrical calibrationLTI Metrology is the calibration lab you can count on for fast, reliable and affordable instrument calibration services and certification. Instrument calibration is a necessity when accurate measurement readings from tools and equipment is crucial for production of quality products.

Why Choose LTI Metrology

To make it easy on you, instrument calibration can be performed at our calibration lab near Philadelphia, PA (USA) or onsite at your facility (in PA, NJ, DE, MD, NY). LTI Metrology is a division of Laboratory Testing Inc., a leader in materials testing since 1984.

LTI has everything you need for reliable verification and certification of your measuring tools and equipment. The Lab is A2LA accredited and performs ISO 17025 calibration services. All calibration measurement results are NIST traceable.

The technicians have well over 200 years of combined calibration experience and work with top of the line equipment. They are qualified to make adjustments and to repair instruments as needed.

Prior to calibration, “As Received” data is recorded for all instruments based on predetermined test points. Any adjustments made during calibration are documented as “As Left” data. Both are reported on the Calibration Certificate, along with the calibration results and all additional information required to be in compliance with ISO/IEC 17025.
