[labnetwork] Cleanroom Particle Monitors

[Jing Guo]

Hi Alex, 

We use Setra 5000 series (remote spec5301SM) in our cleanroom. There are 7 particle counters in the cleanroom connecting to our RAHUs. They are taking samples every half an hour. If the particle counts are over specs, the particle counter will drive the RAHU unit working harder. So far, the whole system is working pretty well. 


Best,
Jing

I was looking at the lasair pro from "Particle Measuring Systems" https://www.pmeasuring.com/ but university procurement is asking me to put together some other options.
