That flexibility extends to Greenlight&#8217;s own customers, too. As they switch gases within a system, flow rates can shift along with the change in molar mass. Alicat&#8217;s high turndown ratio, up to 10,000:1, keeps the reading accurate across that shift, so the data stays reliable even as conditions change mid-test.<\/p>\n<p>The accuracy and stable, dynamic control Alicat provides also gives Greenlight&#8217;s customers confidence in the data itself, from small-scale new product development through larger end-of-line verification and validation.
