The FMA900A Series measures air velocity and provides an analog output proportional to the air flow, and one SPST relay contact closure for high alarm operation. The alarm set point is adjustable from 0 to 100% of the air flow range. The unit comes with one green power LED, and one red LED for alarm indication. The FMA900A Series are used in research and development labs, HVAC applications, exhaust/ ventilation hoods and other manufacturing processes. The sensor probe comes in two configurations, fixed mount 305 mm (12") probe and remote 305 mm (12") probe with 4.5 m (15') of shielded cable.

It is broken
I bought it less month ago. But now it is broken. So I bought another one today. I will send the old one to the company and let them repair it for me.

Do these come calibrated with the calibration values
Thank you for your inquiry. The FMA900A series meter are calibrated but do not come with a calibration certificate. If you need a calibration certificate with the meter, send an e-mail to flow@omega.com and we can provide a quote for the meter with a calibration certificate.
