These accelerometers are for use in inspection, manufacturing and production, and laboratories. Accelerometers are used to measure vibrations and oscillations in machines and installations, as well as in the development of products such as tools or components. It's accelerometers provide the following parameters: vibration acceleration, vibration velocity and vibration displacement. In this way the vibration is recorded with great precision. They are portable devices and their readings can be stored and retrieved for later use. The manufacturer's calibration certificates are included with your first order. Additionally, they can come accompanied with ISO 9000 certification, either with the first order or with it's annual recalibration as stated in the ISO manual.
