VT 204 Tachometer stands out due to its multi-functionality and excels at its ability of accurately measuring three dimensions of vibration. The device, as well as testing for vibration in motors, transmission, gears, wheels, and gear boxes, can also measure rotation of machine parts and rotating components. The attached acceleration sensor can be set flat, equipped with a magnet, or you can combine the sensor with the included fastening screw. Moreover, the internal frequency filters eliminate the effects of background noise allowing the device to detect specific vibrations. If you desire to transfer the readings from the Tachometer to a computer, order the optional software package.
