Title:
SELF-CALIBRATING ELECTROCHEMICAL GAS MEASUREMENT DEVICE AND USE METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/052562
Kind Code:
A1
Abstract:
The invention relates to a self-calibrating measurement device (1) comprising a regulating device (3) configured to admit a fluid medium (10) into a chamber (2), an electrochemical sensor (6) and a control member (7) configured to: - in an amperometry mode (A1), control the admission of the fluid medium (10) into the chamber (2) and determine a first concentration measurement (C1) on the basis of a first electrical measurement (i1) of the electrochemical sensor (6) and a predetermined sensitivity coefficient (k); - in a coulometry mode, prevent the admission of the fluid medium (10) into the chamber (2), determine a second concentration measurement, on the basis of a plurality of second electrical measurements of the electrochemical sensor over a predetermined period of time, for the total consumption of an electroactive gas (11) in the chamber (2) and modify the predetermined sensitivity coefficient (k) on the basis of the difference between the first and second concentration measurements (C1).
