Device for measuring residual oil

Abstract

The invention relates to a measuring device for detecting amounts of hydrocarbon in gases, and comprising—a first sensor (22) for determining the amount of hydrocarbon in a first measurement gas flow (38) and for producing a corresponding first measurement result,—a second sensor (24) for determining the amount of hydrocarbon in a second measurement gas flow (39) and for producing a corresponding second measurement result, and—an evaluation unit for evaluating the measurement results of the two sensors (22, 24),—the first sensor (22) being a metal oxide semiconductor gas sensor and carrying out measurements continuously, and—the second sensor (24) being a photoionisation sensor and carrying out measurements intermittently. (FIG. 1) The invention also relates to a method for recording the amount of hydrocarbon in a gas flow.
