Vibration balance

The utility model provides a vibration balance, this vibration balance include real -time weighing chamber and balanced weighing chamber, wherein: real -time weighing chamber and balanced weighing chamber all include: weigh cavity, hollow conical pipe and flowmeter, balanced weighing chamber still includes: temperature and humidity regulating apparatus, wherein, balance weighing chamber obtains the compensating factor through water vapor content in calculating atmospheric particulates, and real -time weighing chamber utilizes the compensating factor to calibrate the data of weighing in real time, obtains the true concentration of atmospheric particulates. The utility model provides a balanced weighing chamber of vibration balance adoption weighs with real -time weighing chamber is parallel, through the steam in the adnexed atmospheric particulates on the temperature and humidity regulating apparatus elimination filter membrane, adopts this kind of setting, can make vibration balance save conventional membrane
