Mass Calibration

Weight, Balance, Comparator Calibration and More

Mass calibrationMass calibration is performed at Laboratory Testing Inc. by the experienced technicians in the LTI Metrology Lab. The technicians provide a range of mass calibration services including balance calibration, scale calibration, weight calibration and comparator calibration at our climate-controlled facility in the Philadelphia, PA area. Some instruments can also be calibrated on-site at our customers’ facilities by our specially trained field technicians.

Our calibration standards are traceable to NIST and mass calibration is accredited by A2LA. Weight calibration is available for a wide-range of classes, including A, B, C, F, M, P, Q, S, S-1, T, 1, 1.1, 2, 3, 4, 5 and 6, as defined in the specification NBS Handbook 105-1 & 44, NBS Circular 547 ANSI/ASTM E617. LTI Metrology has equipment capable of performing balance calibration, scale calibration and comparator calibration on test items with capacities to over 1,000 lbs.

You’ll get timely, accurate results and an easy-to-read Calibration Certificate with a full report of all work and results. When your instrument is due for re-calibration, we will send you a reminder notice. Pick-up and delivery services are offered for customers within 60 miles of our Hatfield, PA lab, at no additional charge.

The Mass Calibration Process

LTI Metrology is equipped with a number of scales designed to handle mass calibration of standards and instruments at various weights and accuracies. The calibration entails a weight comparison from the scale readout against a known standard or mass value. The precision mass standards used for calibration are of a known accuracy.
