A high-precision electrochemical sensor for easy pumping

Abstract

The invention discloses a high-accuracy electrochemical sensor facilitating liquid suction. The high-accuracy electrochemical sensor comprises an inductive casing with a reaction cavity, wherein a cover plate is arranged at the upper end of the inductive casing, a suction hole is formed in the lower end of the inductive casing, three electrode plates made of different materials are arranged on thecover plate, the three electrode plates are connected with the cover plate and extend into the reaction cavity, the reaction cavity has a round cross section, three positioning grooves are annularlydistributed on the wall of the reaction cavity, fixed supports are arranged on the positioning grooves, two fixed plates forming a 60-degree angle are arranged on the inner side of each fixed supports, one electrode plate is arranged on two adjacent fixed plates of the two adjacent fixed supports, and negative pressure holes communicated with the reaction cavity are formed in the inductive casing.By means of the fixed supports, three electrode plates can be well fixed with one another, so that the distance between every two electrode plates is effectively guaranteed; the fixed supports are detachably connected with the inductive casing, and electrode replacement can be facilitated. The invention applies to electrochemical sensors.

Description

technical field [0001] The invention relates to a high-precision electrochemical sensor which is convenient for pumping liquid and can be used for clinical diagnosis, material analysis, industrial control and environmental monitoring. Background technique [0002] The earliest electrochemical sensors date back to the 1950s, when they were used for oxygen monitoring. By the mid-1980s, small electrochemical sensors began to be used to detect a variety of different toxic gases and solutions within the PEL range, and showed good sensitivity and selectivity. In the process of material chemical analysis, it is often necessary to detect different solutions and gases, so electrochemical sensors are required. [0003] Because the price of the electrode material is very high, in order to save materials, the electrodes are often made thin and thin, but this leads to low strength of the electrodes, making the distance between adjacent electrodes unstable when they are working or being ...
