INTRODUCTION
MEWOI- HS5936 vibration tester is a digital and pocket vibration measuring instrument, which can directly measure the vibration acceleration, vibration intensity (speed), and the weight acceleration value of hand-transmitted vibration frequency meter. It has wide measuring range and maximum value maintenance function, and provides AC and DC output for further analysis of other analytical and testing instruments, mainly used for the measurement of machine vibration, To evaluate the vibration intensity of the machine, it can also be used for the measurement of the vibration of hand tools (such as oil saw, rock drill, air pick, etc.) to evaluate the impact of the vibration of the hand-held tools on the human body (ARM). The measurement of vibration acceleration and vibration intensity conforms to the requirements of ISO2372, ISO2373 and relevant national standards. The measurement of hand-held vibration conforms to the requirements of ISO5439 and GB/T14790, The performance of the instrument meets the requirements of ISO8041. This instrument provides convenience for the mechanical design, manufacturing, power, equipment management, labor protection, transportation and environmental protection departments to detect and monitor the failure and aging signals of machine equipment on-line, to control the product quality, to measure and control the vibration of vibration test and to evaluate the hand transmitted vibration. |
