The Sewer Line Rapid Assessment Tool, or SL-RAT, from InfoSense allows technicians to assess pipes for blockages in three minutes or less. Its active acoustic technology provides a fast screening assessment of overall blockage conditions within gravity-fed sewers. It is portable, GPS enabled, and U.S. EPA validated. A two-person crew can inexpensively screen 10,000 to 20,000 feet of pipe per day. Data can be managed through a cloud-based Web application at www.sl-dog.com. 877/747-3245; www.infosenseinc.com; Booth #4213.
