1.Preface

   HS5633B sound level meter have been developed following China’s new versatile sound meter criterion. HS5633B sound level meter have the following function:Choice of frequency weighting network A or frequency weighting network CChoice of high measuring range and low measuring rangeOver load and low of measuring range indicatesKeeping measuringNumerical indicatingAlternating current signal outputting

HS5633B can be diffusely used in measuring industrial noise such as noise caused by machines, vehicles, watercrafts and used in environment noise.

HS5633B is applicable in different domain, such as industry, environment protecting, traffic, scientific researching.
