摘要： The invention relates to an electrochemical sensor based on an associated sensor, including an interface base and a probe part, where the interface base is provided with two groups of electrical connection terminals, the probe part is provided with a working sensor and an associated sensor, both sensors are provided with a counter electrode, a working electrode and a reference electrode, and the counter electrode of the working sensor and the counter electrode of the associated sensor are the same electrode. The invention adds the associated sensor to the probe part, and the two sensors with high similarity share the same counter electrode, and form an associated relationship with an original working sensor; the associated sensor is equivalent to a “standard ruler”, works in a known calibration environment and provides a standard reference value for the working sensor to be corrected, so as to obtain a more accurate result.

摘要： The present disclosure relates to a redundant electrode-based electrochemical sensor and an attenuation compensation method thereof. The redundant electrode-based electrochemical sensor includes an interface base and a probe portion. The interface base is provided with three electrical connection terminals. The probe portion is provided with a primary electrode sensor and a redundant electrode sensor. The primary electrode sensor and the redundant electrode sensor are respectively provided with a counter electrode, a working electrode, and a reference electrode, and share one counter electrode. The present disclosure realizes that an unknown measurement result of the primary electrode sensor is predicted by means of known characteristics of the redundant electrode sensor, a more accurate correction value is calculated, additional attenuation compensation does not need to be performed, and conventional empirical compensation method and attenuation curve fitting method are abandoned to avoid causing errors.
