Abstract
The invention relates to an apparatus and a method to monitor the condition of a fluid by measuring multiple optical properties of the fluid. The apparatus comprises of a body, at least one fluidic cavityto capture a fluid sample, at least one light sourceto emit an optical signal and at least one optical detectorto detect the optical signal. The fluid sample is collected continuously from a path of a fluid flow and multiple optical properties are measured in real time to determine the condition of the fluid. The apparatus is installed in-line with the path of the fluid flow in the system for which the fluid is being used and monitored. The apparatus avoids environmental contamination and wastage of the fluid sample by returning the fluid sample back into the fluid flow.
