 Overview

All Metal, Fast Response, Low Flow Rates!

The  all metal HFM-300/HFC-302 is Teledyne Hastings' metal sealed, fast response series of mass flow meters and controllers.  Featuring reliability and stability, the 300 Series is chosen by OEM's for its  fast response under a wide range of conditions. .


The HFM-300 / HFC-302 meters and controllers have flow ranges from 0-5 sccm to flows of 0-25 slm; provide analog outputs, are constructed of stainless steel and have normally closed valves. The full scale range  is  specified by the end user.  A NIST traceable calibration certificate is standard.  Corrosive gases and pressures up to 1000 psig are easily measured.  Cleaning for oxygen service is available.

Accuracy

± (0.75% of full scale 5 sccm to 10 slm) 

± (1.00% of full scale 10 slm to 25 slm)
