Not sure what works best?
Your flow rate, pressure, and choice of gas can all affect which Alicat instruments work for your application.
Our Applications Engineers can answer your questions and help you find the best option.
We offer a wide range of solutions for mass flow and gas flow measurement, including thermal, Coriolis, and digital mass flow controllers and meters from brands like MKS, Bronkhorst, Aalborg, Sierra, and Omega. Our instruments support low flow, high-pressure, HVAC, hydrogen, oxygen, LP gas, and argon applications. We also provide analog and digital flow controllers, pressure regulators, fluid control valves, transducers, and transmitters. Services include calibration, recalibration, and flow meter verification. Whether you need inline flowmeters, bioreactor flow control, or medical air flow sensors — we deliver fast and reliable performance across industries.
