Alicat MCE and MCV Mass Flow Controllers (MFC)
Mass flow controllers are a pivotal tool when it comes to any process, which means that you need something fast, reliable, and accurate. The Alicat MCE and MCV Pressure-based Mass Flow Controllers provide a large control range (0.01-100%), fast sensor response time (<1 ms), and an exceptional accuracy. With a plethora of additional options and customizations including different electrical connections and communication protocols, the Alicat Mass Flow Controller line will provide everything that you need to ensure that your vacuum process runs smoothly.
Features & Benefits
