Understanding the technology behind it

Solid polymer electrochemical technology represents a groundbreaking advancement in electrochemical detection. It relies on the principle of electrochemical catalytic reactions. In essence, these sensors respond to target gases by producing a minute electric current signal, typically proportionate to the gas concentration. Traditional electrochemical sensors use liquid or gel electrolytes, which pose operational challenges. EC Sense's solid polymer electrochemical sensors effectively overcome these obstacles.

The inner workings of the technology

EC Sense's solid polymer sensors incorporate a composition of three electrodes in contact with the electrolyte. Each electrode consists of a large surface area of precious metals and other materials. These electrodes, the electrolyte, and the surrounding air interact as the gas diffuses through the back of the porous membrane into the sensor's working electrode. At this stage, the gas is oxidized or reduced. This electrochemical reaction initiates an electric current to flow through the external circuit.

What sets EC Sense ES1 Gas Sensors apart?

While electrochemistry is a familiar concept in the world of gas detection, solid polymer electrochemical gas sensors offer a cost-effective approach for large-scale productions. Additionally, the automated production process ensures consistent and dependable quality. Notably, the EC Sense sensors are impressively compact, facilitating seamless integration into a wide range of applications. There is also no risk of leakage or drying out due to the solid core.
