LR120     Portable vibration meter

LR120 Portable vibration meter, suitable for conventional vibration measurement, especially vibration measurement in reciprocating machinery, it can measure the acceleration, speed or displacement of vibration, but also can measure the frequency of vibration.

This product adopts optimized filtering method, so that in the multi-interference measurement environment, still maintain stable and accurate measurement value.In addition, the product has a compact appearance, white backlight display is clear and easy to read, and has high flexibility in complex use environment.
