MB–Series: Portable Gas Mass Flow Meters
MB–Series Portable Gas Mass Flow Meters measure mass flow and volumetric flow rates anywhere you need for 98+ gases, making them ideal for on-the-go process calibration, verification, and validation.
- Portable & durable. Built to be carried around, with a battery lifetime of up to 18 hours and drop-resistance.
- Versatile & accurate. Real-time measurements with NIST-traceable accuracy to ±0.5% of reading or ±0.1% of full scale for 98+ gases and 20 custom-defined mixtures.
- Fast, multivariate data. Millisecond-response times immediately upon powering up, to display flow, pressure, and temperature readings in real-time, in your choice of engineering units.
