Sound Level Calibrators
-
PeakTech Prüf- und Messtechnik GmbH
For sound level measurements in extreme conditions, at high altitudes or high demands on the accuracy of the measurement results, sound level meters should be checked prior to the measurement with a sound level calibrator. Also for calibration and verification of microphones in audio technology, you need a sound level calibrator, which is designed to produce several sound pressure levels at a fixed frequency characteristic. This calibrator has two switchable calibration steps.

Calibration Equipment
-
Calibration is the method of comparing tools and measuring devices to higher accuracy standards. Torque calibration equipment is the official means by which torque testers and sensors are calibrated and are traceable to National or International Standards, such as N.I.S.T and ISO. In order to maintain precision accuracy, it is essential that torque measuring equipment be calibrated regularly. By equipping your team with Mountz calibration equipment, you can avoid the costly chore of sending your torque tools to the lab whenever they fall out of alignment.
