Selecting an Airborne Particle Counter: Particles in Process Gases (Series Part 4 of 4)

This blog is about choosing a particle counter for gas applications. First, determine whether your process gas is reactive or non-reactive. Then decide its pressure range. Reactive Gases Examples of reactive gases include hydrogen and oxygen. These gases require a special particle counter stored inside a containment vessel. In addition, they require careful evaluation that the wetted materials ...

Particle Monitoring in Sterilizing Tunnels

Portable aerosol particle counters are designed to sample ambient air at 1 cubic foot per minute (1 cfm) and no greater than 35 oC. There are however applications which are based on ambient ...
