Mass Flow Controllers & Meters


MBS–Series: Portable Anti-Corrosive Gas Mass Flow Meters

Alicat MBS-Series portable anti-corrosive gas mass flow meters simultaneously measures mass flow, volumetric flow, gas pressure, and gas temperature of 130+ gases, including 32+ corrosives. Use this portable meter for convenient on-the-go calibration, verification, and validation for processes flowing aggressive gases.

  • Compatibility with corrosives. Wetted materials are compatible with 32+ pure corrosive gases and most refrigerant gases.
  • Portable & durable. These meters are made to be carried around, with a battery lifetime of up to 18 hours and the ability to withstand drops.
  • High-accuracy. Get real-time measurements with NIST-traceable accuracy to ±(0.4% of reading + 0.2% of full scale) for 130+ gases, including custom mixtures defined using Alicat’s COMPOSER™ firmware.
  • Fast, multivariate data. Immediately upon powering up, the meter is ready to display instantaneous flow, pressure, and temperature readings in your choice of engineering units.

Accessories included with purchase:

  • Micro-USB to USB cable for power and serial communication.
  • USB to wall adapter converter with four interchangeable prong configurations.
  • FlowVision software (free download)
