The Model 687A01 Vibration Meter Kit puts predictive maintenance into the hands of machinery operators. Simple enough to use with minimal staff training, it conveniently measures the vibration levels of bearings, gears, and spindles for predictive maintenance requirements. The kit is supplied with an industrial accelerometer, a cable assembly, a high-strength mounting magnet, and headphones for audible monitoring. The portable, lightweight, battery powered meter provides both overall acceleration and velocity measurements. The unit is ideal for measuring the vibration severity of fans, motors, and pumps, and is also useful for verifying the DC bias voltage of industrial accelerometers for troubleshooting permanently installed sensors and cables.
