Our Customers Say:

“I wanted to take the time to personally thank you for the time and effort that LTI has put into the testing involved with our orders. Your staff has been invaluable over the last several years.  Additionally, the fact that you are now able to perform Fracture Toughness testing in house has already proven priceless in both the turnaround time and in getting my questions answered. I’ve been fortunate to have worked with LTI since 1986 and I have come to think of LTI as an extension of Dubose. I look forward to our continued relationship.”

The Scale Calibration Process

LTI field technicians begin scale calibration and balance calibration by inspecting the instruments to be sure they read zero when not in use. Depending on the capacity of the instrument being inspected, a selection of test weights in a range of grams or pounds is checked on the scale or balance to determine the accuracy of the readings. The readings are recorded and special note is made of any weight or measure that is outside of the instrument requirements. In some cases, the technician can make adjustments to correct the accuracy of the scale or balance.
