Described herein is a system to provide continuously measurements of an analyte present in a fluid sample, particularly dissolved oxygen in wastewater. The system comprises a sample chamber absent of ambient light to contain the sample and in many embodiments employs a non-invasive method of measuring the analyte and determining the change over time in the concentration of the analyte. It is also an aspect of the invention to deliver analyte measurements in real-time and provides the operator with feedback in substantially less time after sample collection than previously accomplished in the field. It is another aspect of the invention to simultaneously or at least in a substantially short period of time thereafter measure temperature to remove initial error encountered at the start of analyte measurement at least until the sample chamber reaches thermal equilibrium.
