For miniaturized motors, even the very low vibration during rotation can be considered as defect. Using primitive method of picking up noise through listening stick is not reliable to pick up noise from vibration. With this instrument, you can detect very low vibration noise using a highly sensitive pick-up sensor which can not be affected by ambient noise. You can achieve accurate measurement and judge a product good or bad.
Product Description
Features:
- Detects vibrations caused by unbalanced motors and rumbling noises of bearings.
- Measurement noise can be heard through speakers and earphones.
- Equipped with an external communication function, it can be easily introduced into an automated production line.
