UL Listed vs Recognized. Which approval do you need for your application?
Brooks Instrument knows a lot about agency approvals. If you need a mass flow controller, mass flow meter, or pressure controller for a hose down or hazardous area requirement you came to the right place! We not only have the approvals, but we can also help you understand which approval is right for your application. For example, what’s the difference between UL ‘Listed’ and UL ‘Recognized’ and which one is right for my application?
Well the UL Listed products carry the following mark.

This means that the product has been tested by UL to nationally recognized Safety Standards and has been found to be free from reasonably foreseeable risk of fire, electric shock and related hazards in a Division 2 / Zone 2 environment. The Brooks SLAMF Series thermal mass flow meter/mass flow controller and pressure controllers, and the Quantim IP65 Coriolis mass flow meter/mass flow controller products are all UL listed.
