flowmeters for measuring GC flow

[thohry]

Hi all,

I would like to purchase a flowmeter (portable) for measuring flows in GC (from 0.1 up to 500ml/min).
Please recommend me which makes are appropriate.

Thanks.

I use the Agilent one, ADM1000, works well, but you need to think about getting it calibrated yearly.

Thank you, I am considering that one and the "Precision Gas Flow Meter". I am not sure if the later one needs calibration yearly

Depends on if you work within a quality system. The Agilent one does not specify a calibration interval, but our quality system does.
