Portable Carbon Monoxide Detector with Audible & Visual Alarm for Home, Car, Camping & Travel

The CT-300 is an ideal portable CO tester to help you detect CO gas concentrations in a timely and accurate manner, reducing the risk of CO poisoning and protecting your life. It is a must-have tool for homeowners, drivers, campers, DIY-ers, tourists, and more.

The CT-300 features an advanced electrochemical sensor head that swiftly detects CO levels from 0-5000 ppm. Its sensitivity ensures early warnings, allowing timely actions to prevent health risks. Accurate readings empower quick decisions, promoting safety and well-being. Versatile and portable, it guards against CO in various settings, ensuring peace of mind.

The travel CO detector uses both visual and audible alarms. When the concentration of CO reaches the alarm threshold, the screen changes color and emits an urgent alarm sound to alert you of the presence of CO gas in your surroundings, allowing you to promptly detect the danger and protect yourself.

Regarding the user-friendly functions, the CT-300 is made with high-quality ABS+PC material and has an anti-slip edge texture, making it durable and portable. It can be used for 40 hours with new batteries, and a low-power indicator will remind you when it's time to change the batteries. The device will automatically switch off when not in operation or when no gas is detected within 10 minutes, to save power. Additionally, it has a backlit screen for easy viewing, making it adaptable to dim environments.

What should you pay attention to before using the CT-300? Please open the device in clean air (such as outdoors with ventilation) and wait for the preheating to complete, which is expected to take 5 seconds.

Why do you smell gas leakage but the CT-300 doesn't display any values? Carbon monoxide is a colorless and odorless gas. The odor you're smelling may not be from carbon monoxide gas. Try using a combustible gas detector for testing.

Why can't carbon monoxide be detected in a closed room? When there is no significant source of combustion indoors, even in a closed room, carbon monoxide will not be generated. The gases exhaled by humans contain carbon dioxide (CO2), which is a different gas from carbon monoxide (CO).

Why can't carbon monoxide be detected even when there is a combustion source present? Not all combustion produces CO gas, only incomplete combustion does, which is characterized by a red/yellow flame in most cases. Also, ensure proximity during measurement to prevent gas dispersion, which may lead to undetectable concentrations.
