摘要

Procedure and optical module for the measurement of absorbance to discrete lambdas for water quality control applications. The invention relates to a method and an optical module for the measurement of absorbance and other physical-chemical parameters to discrete lambdas, particularly intended for water quality control applications, comprising power means, optical emission means, optical separation means and first and second optical reception means. It also comprises means for conducting or containing a water sample interposed between the emission means and the receiving means and means for detecting and comparing the signals received by the first and second optical reception means, said means comprising detection of lock-in amplifiers and the optical emission means being leds.
