Tektronix is the world's leading provider of multi-vendor calibration, repair and related services. We create sustainable value for companies that rely on test, measurement and control instrumentation, through the world's most extensive network of measurement professionals, facilities and resources.

We calibrate testing machines up to 1,000,000lbf primarily in compression, but can do some limited tension calibration up to about 10,000lbf. We also calibrate other laboratory equipment such as small scales, load rings, load cells, linear and linear variable devices and other equipment mostly found in the Geotechnical lab. We represent most concrete testing machine manufacturers in service and consider ourselves to be the company to go to for advice on your next testing machine.

Cal One Systems is the alternative to the "big box" measurement and testing companies that have become so prolific. We pride ourself in being a boutique laboratory that is sensitive to our customers needs and provide the service our customers expect. Measurement Uncertainty (MU) is a matter of daily routine rather than some required mathematical chore. MU is unique for every measurement made in our Labs, as it was intended. All correspondence done in person, over the phone, or email is done "old-school" . You will never be placed in a que because we understand your most valuable asset is time.
