Carbon dioxide detectors are essential for businesses that store, produce or use stored carbon dioxide (CO2). Exposure to high levels of CO2 can cause dizziness, headaches, fatigue, asphyxiation, and in extreme cases, death. CO detectors monitor the concentration of CO2 in a room or space, and if an unsafe level is detected, they will alarm.

There are Forensics Detectors  different types of carbon monoxide detectors on the market, each with its own pros and cons. The two main types are electrochemical and photoelectric, with both providing a safe level of protection against toxic levels of CO2.

Electrochemical carbon monoxide detectors have a sensor that consists of a container, two electrodes, connection wires and an electrolyte such as sulfuric acid. Carbon monoxide enters the sensor and oxidizes to carbon dioxide, and oxygen is consumed at the other electrode. The resulting current is proportional to the concentration of carbon monoxide.

Monitoring Carbon Dioxide Levels: Ensuring Safety and Comfort with CO2 Detectors

These detectors can be battery-operated or AC powered, with most offering a test button to check the battery, circuitry and buzzer (not the sensor). Most models are designed to signal that the sensors need to be replaced after a certain period of time. All CO detectors must comply with minimum sensitivity and alarm characteristics established by Underwriters Laboratory (UL). Some models have a digital display that provides real-time readings of the carbon dioxide level down to a few ppm. These devices are typically used in hospitals and for industrial applications, as well as by hygienists and safety professionals.
