Hi Everyone, I was wondering what people use for particle measurement systems in their cleanrooms? We are trying to add active particle monitoring to our cleanroom facilities. I was looking at the lasair pro from "Particle Measuring Systems"
<a href="https://www.pmeasuring.com/" target="_blank">https://www.pmeasuring.com/</a> but university procurement is asking me to put together some other options.  </div>
