Certified airflow analyzer, maybe it’s not the best.Because there are many business factors that affect.
For example, I have used the Fluke VT650,In low tidal volume state, VT650 cannot complete analysis,Only test parameters recommended by the manufacturer can be used for analysis.These test parameters are very moderate and have no limit values.
If you're looking to complete a standard PM job, it can get the job done,But if you hope to challenge the limit, you will fail.
Maybe VT900 can, but VT900 is too expensive
So I have been using Respical T300, Timeter-RT200.
Citrex H5 looks similar to Fluke VT650, I mean performance specs,It's capable of doing normal PM work, but if you want to test it to the extreme, I'd be skeptical
