Frequently Asked Questions
Condensation Nuclei Counting (CNC) uses airborne particles as the challenge agent. With the AeroFit, fit factor is measured by comparing the concentration of particles inside the respirator to the concentration of particles outside the respirator. A total fit factor calculation is used to determine the overall fit factor of the respirator on the test subject.
The amount of records the QuantiFit2 and the AeroFit can hold is virtually unlimited from a practical standpoint. The internal storage should allow hundreds of thousands to millions of test records to be stored.
