The welded single-oven instrument with secondary dilution (SD) is our most versatile moisture system. This instrument provides an internal secondary dilution step that allows addition of extremely low concentrations, production of a very wide concentration range (up to 20,000:1), and the production of variable concentrations in a fixed total flow.
