Your Sound Level Meters & Calibrators Source

IET Labs offers a complete line of sound level meters and vibration measurement instruments formerly manufactured by GenRad. Although these sound level meters are designed to operate on their own, much thought was given to their use in a variety of systems to solve specific measurement problems. The industry standard 1565 sound lever meter and 1562 sound level calibrator will satisfy most any requirement.
