Handheld Laboratory Flow Meters

Portable gas flow meters make GC checks, calibrations and audits fast and easy. They fulfil a number of lab measuring functions all within the one device!

AFS–Portable Gas Flow Calibrators


A portable gas flow standard that is ready for anything

AFS–Portable Gas Flow Calibrators

When a calibration process requires the utmost accuracy, the AFS flow standard delivers. It features Alicat's most advanced calibration for optimal performance across changing temperatures, plus an on-board relative humidity sensor to maintain its accuracy all the way up to 100% RH (non-condensing). These advancements make possible a 0.75% of reading accuracy spec that requires no additional full-scale component. Low pressure drop allows calibration of volumetric flow rates with minimal impact. Averaged measurements and onboard data logging make it easy to gather multivariate flow data.

MB–Portable Gas Mass Flow Meters


Laboratory-grade flow verification, anywhere you need it

MB–Portable Gas Mass Flow Meters

Alicat's portable flow flowmeters make calibration or validation simpler and faster by reducing downtime and disruption. Instant-on and real-time readings for multiple gases across wide flow ranges ensure periodic checks can be completed within just a few minutes. Flows can be calibrated with NIST-traceable accuracy for a variety of gases down to 1/200th of full scale or user-created gas compositions can be defined via COMPOSERTM.

MWB–Low Pressure Drop Portable Gas Mass Flow Meters


Measure flow with minimal system impact, anywhere you need it

MWB–Low Pressure Drop Portable Gas Mass Flow Meters

"Whisper" series portable flow meters with low pressure drop are the perfect measuring and calibration instruments for mass and volumetric flow rates. Low pressure drop minimizes system impact, enabling flow measurement at near-atmospheric pressures or when there is little available system pressure.
