Instrument Calibration
Don’t Guess: Accurate Instruments Do the Job Correctly
LTI Metrology at Laboratory Testing Inc. is the calibration laboratory you can count on for accurate and affordable instrument calibration services. Many factors can send measuring tools, instruments and masters out of tolerance including environmental conditions, time and excessive use. If your company’s tools and instruments are crucial to producing quality products, you and your customers can’t afford the risk of measurement error.
Our calibration process combines top of the line equipment, NIST-traceable standards and highly experienced technicians to verify the measurement accuracy of your instruments. Adjustments and repairs can be made as needed. To make it easy on you, instrument calibration can be performed at our PA calibration lab or onsite at your facility.
LTI Metrology provides A2LA accredited calibration services for a wide-range of instruments. A detailed list of Company Instrument Calibration Service Listing in each of the categories below can be reviewed on our Resources page.
