The Alicat Scientific MC series mass flow controllers were designed to take the guess work out of precision gas flow control. Designed for simplicity, the Alicat Scientific mass flow controllers are very easy to use. The local display permits changes to the configuration of the unit without the need for computers, complicated software or scripts.

The Alicat Scientific MC series mass flow controllers have a standard accuracy calibration of ±(0.8% of reading + 0.2% of full scale). A high-accuracy calibration of up to ±(0.4% of reading + 0.2% of full scale) is also available. The MC series mass flow controllers have very few moving parts. All of the internal components are fixed in place, resulting in very little physical change inside the controller, resulting in higher rates of consistency and a repeatability of ±0.2% of FS.

The Alicat Scientific MC series mass flow controllers require very little power to run thereby reducing operating costs. The MC series flow controllers also have less pressure drop when compared to similar flow devices. Reduced pressure drop means more process fluids go into your process and not into the measurement devices. The MC series mass flow controllers also measure pressure, temperature, and volumetric flow in addition to mass flow which means fewer instruments to buy and install.
Alicat Scientific MC series mass flow controllers have a response time of less than 10 milliseconds and a control time of 100 milliseconds, making it one of the fastest naturally responding mass flow controllers on the market today. They are equipped with multiple analog outputs and inputs. Adding a totalizer allows users to see how much media has flowed through the controller, making it a great way to monitor usage and identify waste. The Alicat Scientific MC series mass flow controllers can also be used in applications where flow control into a vacuum is critical. The modular design allows it to be used in systems in which flow is driven by a vacuum.

The Alicat Scientific MC series mass flow controllers are ideal instruments for a variety of processes including: fuel cell testing, vacuum coating, sputtering, process automation, semiconductor processing, micro electro mechanical (MEMs), solar cell manufacturing and flame tip control.
