2 in 1 of three-channel PM2.5 detector

Purification efficiency detector

Multi-usage, can detect the weight and particles of PM2.5

Detection of PM2.5 is no longer needed more than machine

measurement of the quantity and quality of the fine particles at the same time.
35 seconds sampling
Detecting three kinds of particles 0.3μm, 2.5μm, 10μm:
Accurate detection of PM2.5 and PM10, sampling time 35 seconds

Compare feature:

After two measurements before and after showing the purification efficiency and more convenient after comparison

The main technical indicators
0.3μm,2.5μm 1 0μm:

knowledge
Under 100 micron particles for total suspended particles in the air (TSP)
Above 10 micron particles can be inhaled particulate matter(PM10)
Under 2.5 micron particles for particulate matter can go into the lungs (PM2.5)
Single filter net rate: refers to the mesh inhalation of air into the fresh air from a single process, by comparing the change of air particles number to determine the mesh filter net
Use the instrument to measure the purification efficiency of air purifier , prepare a new filter, And let the machine work more than 20 minutes, Usually use within 3 months, if the machine use for a long time, need to replace a new purifier HEPA filter, so that make the effect is obvious.
