Laboratory grade flow verification, anywhere you need it

Alicat MB Series portable mass flow meters monitor your mass and volumetric flow as well as your process pressure and temperature. This is all done simultaneously and every MB series comes preloaded with 98 gases and gas mixtures, you can even add your own gas blends! Now equipped with up to 18 hours battery life and a 3.5 hour recharge time via USB charger.

The portable mass flow meter is repeatable and accurate with calibrations up to ±0.5% of reading accuracy.

Every device has a 10,000:1 turndown ratio with full scale flow rates starting from 0.5 SCCM and going up to 5000 SLPM.

Alicat MB Series comes with a backlit LCD as standard, along with RS-232 communications over a USB type B connection.

Every Alicat device is backed by the manufactures limited life time warranty and ships with a NIST traceable calibration certificate.

MB series portable mass flow meters have a maximum operating pressure of 175 PSIG.
