Thank you for purchasing the Setra FLEX, the industry’s most advanced and flexible room environmental monitor. Setra FLEX is designed for indoor use only to monitor critical environments by providing differential pressure indication and additional parameters such as temperature, relative humidity, air changes per hour, and user-defined information. Typically this is between a monitored room and a reference space such as a corridor or ante room. - Page 44 Setra FLEX Operating Instructions Setra Systems, Inc. 159 Swanson Road, Boxborough, MA 01719 800.257.3872 • www.setra.com SS-FLEX Install Op Rev.
