Upgrades

United Universal Testing Machines are known for their reliability and longevity. We often provide routine service to customers whose machines have been in daily use for more than 25 years. If you have an older United SMART Model computerized testing machine, you may want to consider a software and/or hardware upgrade to bring your machine up to current specifications. An upgrade is often a practical alternative to replacement of a machine which could provide many additional years of trouble-free service.

Lab Service

Force Laboratory

United provides force calibration from 0 to 500,000 pounds in accordance with the requirements of ASTM E-74 and from 0 to 1,000,000 E-4 with IAS accreditation (Calibration Laboratory CL – 128).

Load Cells (high accuracy)

United load cells provide force calibration (in house) to 500,000 pounds with accuracy of 0.05% and to 1,000,000 pounds (on-site) with an accuracy of 0.25%

Force Calibration

United’s automated dead weight tester provides calibration to 5,000 pounds force in 5-pound steps with accuracy of one part in 250,000 or Class C weights.

Proving Rings

United proving rings provide force calibration to 400,000 pounds. Accuracy: 0.02% to 60,000 pounds, 0.05% to 400,000 pounds.
