Ultima X Series Gas Monitors

Electrochemical sensors are sealed units which contain a corrosive electrolyte. Should a sensor develop leakage, it must be immediately removed from service; then, remove it from the sensing head and discard it properly. Caution must be exercised so that the electrolyte does not contact skin, eyes, clothing or circuitry; otherwise, serious personal injury (burns) and/or equipment damage may ...

Create Your Own CO Detector - Digi-Key

Building a CO (carbon monoxide) detector that can alert you to dangerous levels of CO can be done with as little as a gas sensor, an Arduino (or other microcontroller) and some resistors. Adding a few op-amps can boost the sensitivity to measure the amount of CO present in the environment. Expanding on this knowledge, you can build your own air quality monitoring station, and compare your own ...

Carbon monoxide detector - Wikipedia

The electrochemical detector uses the principle of a fuel cell to generate an electrical current when the gas to be detected undergoes a chemical reaction. The generated current is precisely related to the amount of carbon monoxide in the immediate environment close to the sensor. Essentially, the electrochemical cell consists of a container, two electrodes, connection wires and an electrolyte ...

2018-10-15· The carbon monoxide sensor consists of three electrodes immersed in a liquid electrolyte (a non-metalic liquid that conducts electricity, usually through acids or dissolved salts). The three electrodes are the working electrode, the reference electrode, and the counter electrode. The most important of these is the working electrode (WE).
