AFS–Portable Gas Flow Calibrators
A portable gas flow standard that is ready for anything
When your 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 1% of reading accuracy spec that requires no additional full-scale component.

Accurate. Calibrate flows with NIST-traceable 0.75% of reading accuracy for a variety of gases, or define your own gas composition with COMPOSER™. Low pressure drop allows calibration of volumetric flow rates with minimal impact.
Fast & Easy Operation. Averaged measurements and onboard data logging make it easy to gather multivariate flow data (volumetric and standardized flow rates, ambient and line pressures, and line temperature).
Durable. AFS flow standards are designed to be carried and can withstand drops if they should occur. Process connections have SAE threads for superior leak prevention.
