The HFM-300/HFC-302 can support the following variety of applications: Leak Testing, Flame Spray, Gas Blending, R&D Process Flows. Cleaning for oxygen service is available. Corrosive gases and pressures up to 1000 psig are easily measured. A NIST traceable calibration certificate is standard. The full-scale range is specified by the end user. 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. Featuring reliability and stability, the 300 Series is chosen by OEM for its fast response under a wide range of conditions. The all metal HFM-300/HFC-302 is Teledyne Hastings metal sealed, fast response series of mass flow meters and controllers. The HFM-200/HFC-202 can support the following variety of applications: Air Sampling, Industrial Furnaces, Gas Blending, R&D Process Flows, Analytical Instrumentation, Catalyst Characterization. Many corrosive gases and pressures up to 1000 psig are easily measured. The HFM-200 / HFC-202 meters and controllers have flow ranges from 0-10 sccm to flows of 0-25 slm provide analog outputs, are constructed of stainless steel and have normally closed valves. A wide choice of elastomer seals makes this flow controller compatible with most gases. Featuring reliability and stability, the 200 Series is chosen by OEM for its very stable performance with varying ambient conditions. The HFM-200/HFC-202 is Teledyne Hastings flexible, general purpose series of mass flow meters and controllers. There will be no appreciable linearity change of the instrument when the flowing gas is changed. Should recalibration in the field be desired (a calibration standard is required), the customer needs to simply set the zero and span points. The HFM-210/HFC-212 series is inherently linear (no linearization circuitry is employed). Instruments are normally calibrated with the appropriate standard calibration gas (nitrogen) then a correction factor is used to adjust the output for the intended gas. No damage will occur from the use of moderate overpressures (~500 psi/3.45MPa) or overflows. Hastings mass flow instruments do not require any periodic maintenance under normal operating conditions with clean gases. Low Flow Meters and Controllers The Hastings HFM-210 mass Flowmeter and HFC-212 flow controller are designed to accurately measure and control mass flow over the range of 10 sccm to 30 slm, without corrections or compensations for gas pressure and temperature with an accuracy of better than ☑% FS.
