Oscillating balance and atmospheric particle concentration monitoring method

The invention provides an oscillating balance and an atmospheric particle concentration monitoring method. The oscillating balance includes a real-time weighing chamber and a balancing and weighing chamber, wherein each of the real-time weighing chamber and the balancing and weighing chamber includes a weighing cavity, a hollow conical tube and a flow meter; and the balancing and weighing chamberfurther comprises a temperature and humidity adjusting device, wherein the balancing and weighing chamber obtains a compensation factor by calculating the water vapor content of atmospheric particles,and the real-time weighing chamber uses the compensation factor to calibrate real-time weighing data in order to obtain the true concentration of the atmospheric particles. The oscillating balance uses the balancing and weighing chamber and the real-time weighing chamber to weigh in parallel, and eliminates water vapor in the atmospheric particles attached to a filter membrane through the temperature and humidity adjustin
