Accurate and Portable Gas Flow Calibration

Alicat's AFS is a portable gas flow standard for when your calibration process requires the utmost accuracy. 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.

AFS allows 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).

AFS is available for full scale flow rates of 5 and 500 SCCM as well as 5, 20 and 50 SLPM. When flow air Alicat's 200:1 turndown applies or 20:1 when flow other gases or gas mixes.

Define Gas Compositions with COMPOSER™

The AFS is Accurate. Calibrate flows with NIST-traceable 0.75% of reading accuracy for a variety of gases, or define your own gas composition with COMPOSER™.

COMPOSER™ allows you to define gas compositions to 0.01% for each of up to 5 constituent gases, without compromising your Alicat’s accuracy. Low pressure drop allows calibration of volumetric flow rates with minimal impact

Applications

  • Calibration of mass flow controllers inside dynamic dilution calibrators
  • Preparation of the flow controller for an air sampling canister
  • Calibration of gas analyzers, pumps and air samplers for industrial hygiene applications

Other features

  • Flow accuracy: +/- 0.75% of the reading (NIST-traceable)
  • Typical measurement response time constant: 5-10 ms
  • No warm-up time required
