    The 07931-Series Laser attaches to process flanges that you must weld either to the relevant process pipework, duct or furnace wall or, for pipework up to 150 mm (6 ") in diameter, to a spool piece supplied by Servomex. You can attach the laser analyser mounting assemblies (fixed or adjustable) to the process flange either directly with appropriate gaskets, or via an isolation valve or an isolation window, depending on your application.
