Since
1976 the Rothe corporate office has maintained an in-house calibration
facility to support various government and commercial contracts.
This facility specializes in precision calibration and repair
of a wide variety of test equipment including:
As a convenience to our customers and using special web-based
software, we now offer online viewing of job status and ability
to download calibration data and certifications of your test
equipment which was calibrated or repaired in our laboratory.
