Abstract: This is a measuring tool for use in the installation of metal roofing when such metal roofing must be cut in order to fit along valleys in the roof structure. Valleys are places where the roof surface changes direction, such as where the roof of a gable joins the main body of the roof. The tool measures the point at which the metal roofing panel is to be cut by sliding the base of the tool down the last rib of the last installed panel until the tip of the pointer arm touches the chalk like along which the next panel must fit. The distance from the top of said last panel to the bottom of the base of the tool corresponds to the distance from the top of the new panel to the point at which its leading edge should be cut to fit along the chalk line.

Abstract: The present disclosure provides for analysis systems that are configured to extract a fluid sample from a fluid (e.g., aqueous solution) in a reactor (e.g., bioreactor) at a first rate and then flow the fluid sample to a sensor system at a second rate to analyze the fluid sample.
