Finer control of gas mixtures

New to Gas Select 5.0, the COMPOSER utility gives users the ability to quickly program and store up to 20 personalised gas compositions directly on Alicat mass flow meters and mass flow controllers. With COMPOSER’s capabilities, Alicat devices adapt to a range of laser manufacturing applications and users’ changing needs.

The Gas Select firmware comes standard on all Alicat mass flow meters and controllers. Version 5.0’s expanded library now includes up to 130 preloaded full gas calibrations, depending on the Alicat instrument series. In addition to many pure gases, Gas Select 5.0 includes six gas mixes common for carbon dioxide and helium-neon lasers. The library has also been updated to include complete NIST Ref Prop 9 gas properties data for the preloaded gases and gas mixes.

Using the device’s integrated digital display, users can define gas compositions to 0.01% for each of up to five constituent gases.
