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
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
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
"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.
