How does the TSI Portacount work?

How does the TSI Portacount work?

The Portacount works by measuring the concentration of microscopic dust particles in the ambient air and then measuring the concentration of those dust particles that leak into the respirator.

What does a Portacount measure?

It uses the microscopic particles that exist in ambient air to measure the fit factor directly. The PORTACOUNT measures the concentration of these par- ticles around the person’s head and then measures the concentration of those particles that leak into the respirator. The ratio of these two numbers is the fit factor.
