INTRODUCTION
MEWOI- HS5933A environmental vibration level analyzer is based on HS5933 environmental vibration level meter, which has the functions of data storage, analysis and printing. It is an intelligent, light and portable environmental vibration automatic measuring instrument, which is composed of host and printer. The instrument has the characteristics of automatic range conversion, LCD digital display, maximum value holding, automatic measurement of equivalent continuous vibration level, statistical vibration level, etc. the printer can automatically print out various measurement results. The performance of the instrument meets the requirements of ISO8041-1990《human body response vibration meter》for type 2 vibration measuring instrument, and meets the requirements of ISO2631《evaluation of human whole body vibration》and GBl0071-88《measurement method of environmental vibration in urban area》. MEWOI-HS5933A environmental vibration level analyzer is easy to operate, easy to use and reliable. It is widely used in labor protection, environmental protection, industrial health and other departments. |
