LTI Constructs State-of-the-art Calibration Lab
Construction of a 6,000 sq. ft. state-of-the-art Calibration Lab was recently completed at Laboratory Testing Inc. The design nearly doubled the space previously occupied by the calibration staff and streamlined the shipping/receiving and order entry functions for the department known as LTI Metrology. The latest technology for lighting optimization, environment control and vibration control was incorporated into the new construction for optimum accuracy and efficiency.
LTI Metrology provides dimensional, pressure, force, torque, mass and
vacuum calibration services. Dimensional calibration of thread rings and
hand tools takes place in a temperature and humidity-controlled room to
stabilize the instruments before measurement. Length standards and other
masters are calibrated in a separate "cold" room, which is continuously
monitored to maintain an environment within the guidelines of 68 degrees
± 1 degree and 30-50 percent relative humidity. The cold room is lit with
120-150 ft. candles of indirect lighting to prevent shadows and glare.
The dimensional lab, cold room and pressure/torque/force room were each
built on isolated foundations to minimize vibration effects from surrounding
departments in the facility. 
LTI Metrology also provides field calibration service for surface plates, hardness testers, optical comparators, balances, hand tools and testing machines. Repairs, new instruments and replacement parts are available.
