Electrochemical CO gas sensor Introduction
Electrochemical CO gas sensor is an electrochemical sensor which can realize quantitative measurement of carbon monoxide gas through electrochemical principle. The detection principle of carbon monoxide sensor is to use carbon monoxide to produce REDOX reaction on the working electrode and the counter electrode and release charge to form current. The generated current is proportional to the concentration of carbon monoxide, and the concentration of carbon monoxide can be measured by measuring the current.
Electrochemical CO gas sensor has the characteristics of high sensitivity, fast response speed, not easy to be interfered with, wide use, easy installation, plug and play and so on. Widely used in industrial and environmental protection areas of carbon monoxide concentration detection.
Electrochemical CO gas sensor Features:
1, small size, light weight
The machine is compact in size, light in weight and easy to install. It can be used in portable, fixed, pipe type and other appearance sensors.
2. High-performance chip
Breakthrough process technology, three electrode structure design product performance significantly improved.
3, temperature compensation function
Built-in temperature compensation function, factory accurate calibration, direct use, no need to use again calibration.
4, high resolution sensitivity

WHAT IS CARBON MONOXIDE?
Carbon monoxide is a carbon-oxygen compound with a chemical formula of CO. It is usually a colorless, odorless, and tasteless gas. At the same time, it is toxic. Higher concentrations can cause people to have different levels of symptoms of poisoning, harm the human brain, heart, liver, kidney, lung, and other tissues, and even death by electric shock. The minimum lethal concentration of human inhalation is 5000 ppm (5 minutes).
WHERE DOES CARBON MONOXIDE COME FROM?
Coking, ironmaking, and other production processes in the metallurgical industry
Synthetic ammonia, methanol, and other production processes in the chemical industry
Mine blasting and coal mine gas explosion accidents
Exhaust emissions from vehicles and other vehicles
Incomplete combustion of fuel in the boiler
Gas or liquefied gas pipeline leaks from coal stoves in family rooms, natural disasters such as volcanic eruptions, forest fires, earthquakes, etc.
WHAT IS THE HARM OF CARBON MONOXIDE?
Carbon monoxide is an atmospheric pollutant. It is the most abundant and widely distributed in the atmosphere. It is the product of incomplete combustion of carbonaceous materials such as coal and petroleum.
