The Teledyne Hastings HFC-207 are a flexible, general purpose series of mass flow meters and controllers accurately measure and control mass flow in a variety of applications. Featuring reliability and stability, the 200 Series is chosen for its very stable performance with varying ambient conditions. A wide choice of elastomer seals make this flow controller compatible with most gases. The HFC-207 meters and controllers have flow ranges from 0-1000 slm to flows of 0-2500 slm; provide analog outputs, are constructed of stainless steel and can be configured with normally open or normally closed valves. The full scale range is specified by the end user. A NIST traceable calibration certificate is standard. With a full complement of fitting and elastomer options, the HFC-207 covers a wide range of high flow applications.
