How Do Light Scattering Airborne Particle Counters Work?

So the airborne particle counter uses a vacuum or another method to force air into the sensor housing, where the air then passes through the laser projected by the laser diode. The photodetector recognizes how much light is displaced by the laser, so it can then quantify the number and size of the particles that passed through the sample view ...

Vacuum Pressure: What is it how do you measure it?

Setra''s Vacuum Sensors; Vacuum Pressure. By definition, vacuum is a space that is partially exhausted (as to the highest degree possible) by artificial means (such as an air pump). This definition is referring to a high or hard vacuum. Figure 1 illustrates that relationship of absolute and gauge pressure with 0 PSIA equal to a high or hard vacuum.
