Local Exhaust Ventilation (LEV) System Measurement Techniques 

It's a nice way to share information about Air sampling, Noise monitoring, etc. It was very helpful information for new MIHS Students.

Thank you so much for great information really crisp information

I couldnt really hear you with the system on. Couldnt you explain the process with example readings and have the system off? But thank you for trying to explain the procedure clearly

Duct transport velocity needs to be proportional to the density of the particles is that right...??
