Abstract
A system for obtaining reliable data from a chemical sample for at least one variable environmental condition utilizing a photometer. The photometer obtains sample characteristic data at a plurality of discrete wavelengths. The reliability of the data is determined by obtaining a training set of data, and obtaining a number representing the variation between the mean center of the training set of data and the data representing the sample characteristic obtained by the photometer. Such number represents the basis of determining outliers of the data representative of the reliability of the data.
