The carbon monoxide detector with dedicated sensors continuously monitor the surrounding atmosphere, while the clear color display provides easy-to-read gas concentration data in real time. With audible, visual, and vibration alarm functions on supported configurations, the detector helps users identify abnormal gas levels and potential atmospheric hazards more quickly.

Q1: What is a gas detector?
A1: A gas detector is an instrument for gas leakage concentration detection, including a portable gas detector, handheld gas detector, fixed gas detector, online gas detector, etc.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: What is ppm of gas detector?
A3: Parts per million or "ppm" is often used as a fractional measure of concentration. For example, a methane (molecular) concentration of 2% means that 2 out of every 100 air molecules are methane. Likewise, a methane concentration of 2 ppm means that 2 out of every 1 million air molecules are methane.
Tips: Can the detector monitor CO and CO₂ simultaneously?
Yes. A 4 in 1 CO & CO₂ gas detector equipped with dedicated sensors can monitor carbon monoxide (CO) and carbon dioxide (CO₂) simultaneously. The device continuously samples the surrounding air and processes the signals from each sensor independently, allowing multiple gas concentrations to be displayed in real time on the screen. This provides a convenient way to monitor different atmospheric conditions with a single portable instrument.
Simultaneous CO and CO₂ monitoring is especially useful in workshops, industrial facilities, boiler rooms, garages, laboratories, warehouses, HVAC inspections, construction areas, and other enclosed or poorly ventilated spaces. CO monitoring helps identify potential carbon monoxide hazards from combustion sources, while CO₂ monitoring provides useful information about ventilation and changes in indoor air conditions. With real-time readings and high/low concentration alarms on supported models, users can respond more quickly when gas levels reach preset thresholds.
