Working Principle:
Under the action of the suction pump, the sample air separates the particles to be tested from the cutter and deposits them on the sampling filter membrane. After weighing the mass increment with an oscillating balance, the basic mass concentration is calculated based on the volume of the sample air during that period. The oscillating balance method particle monitoring instrument with volatile compensation device also needs to pass the sample gas through a constant temperature zero gas filter and then through a sampling filter membrane in the next period. The mass concentration during this period is the reference mass concentration. The final concentration is the base mass concentration minus the reference mass concentration.

　　Instrument features:
Quality detection sensor: Micro mass oscillation balance.
Flow measurement and control: Quality flow control.
◆ Equipped with a volatile concentration compensation device that is not affected by temperature.
◆ Optional cutters: TSP, PM10, PM5, PM2.5, PM1
◆ Adopting a combination of graded cutting and loss free splitter. The dual channel instrument uses a 15L/min PM2.5 cyclone cutter.
8.4-inch industrial grade true color screen, touch screen operation, Chinese operation interface.
Real time concentration curve display and three-dimensional state diagram display vividly and intuitively show the various parameters of the instrument.
Fully automatic process control, the vacuum pump is controlled by a program, with low power consumption.
