MC–Series Gas Mass Flow Controller
Brand: Alicat ScientificMC-Series Gas Mass Flow Controllers rapidly reach setpoints and maintain stable control of mass flow, volumetric flow, or pressure for 98+ gases across a very wide flow range – 0.01% to 100% of full scale. Highly customizable for easy integration.
Devices are custom ranged from 0.5 SCCM full scale to 5,000 SLPM full scale.
Features- Multi-variable process measurements: Simultaneously measure mass flow, volumetric flow, gas pressure, and gas temperature
- User changeable units of measurement: Change the unit of measurement for pressure, flow, or temperature from our extensive list of engineering units
- Gas Select: Select your process gas from any of the 98+ preloaded NIST-traceable gas calibrations in our gas list
- Composer™: Define 20 custom gas mixtures of up to 5 constituent gases using our Composer™ firmware
- Monochrome backlit LCD with integrated touchpad: Easily read measurements using the backlit display and control configurations with the user-friendly integrated touchpad
- User adjustable setpoint ramping & limits: Configurable ramp rates allow the process variable to be controlled as fast or as slow as desired, and configurable setpoint limits protect processes from inadvertent setpoint changes
- User adjustable standard temperature and pressure (STP) conditions: Quickly change reference conditions without need for recalibration
- Valve close override and valve open override: Utilize alarms to quickly vent your system or stop all flow as needed
