Carbon monoxide detector alarm with LCD display and UL2034 certificate for home

A carbon monoxide detector alarm is a must-have safety device for every home with a gas heating system or kitchen fireplace. This high-sensitivity carbon monoxide detector alarm quickly detects invisible and rising gases that can be deadly to humans. The device has a built-in electrochemical sensor that responds accurately to even very low concentrations of carbon monoxide. The automatic LCD display shows the actual gas concentration in PPM units, so you can monitor the air quality. The product is certified to the UL2034 standard, guaranteeing the highest safety and reliability for the protection of your family.

Carbon monoxide detector signal — key features

• Four-level signaling standard — Up to 50 PPM there is no warning, the screen shows the concentration; 50-100 PPM warns within 80 minutes; 100-300 PPM – within 30 minutes; above 300 PPM – within 3 minutes, ensuring your family’s rapid protection.
• High sensitivity and accuracy — An integrated electrochemical sensor constantly monitored air quality, detecting the smallest traces of carbon monoxide and responding immediately by emitting an audible signal.
• Simple installation procedure — No need for electricians or complicated installations. The device operates on two AA batteries (not included), so it works even when the power supply is turned off.
• Bright LCD screen — The digital display constantly shows the carbon monoxide concentration level in PPM units, allowing you to quickly understand the air condition.
• Monophonic 85 dB signal with LED flashlight — When dangerously high gas levels are detected, a loud alarm sounds and a red LED light flashes, drawing attention throughout the house.
• Universal area of use — Suitable for kitchens, bedrooms, bathrooms, hotels and travel. Ideal for garages, steam rooms and other areas where carbon monoxide can accumulate.
• UL2034 certificate — Meets international safety standards, guaranteeing professional sensitivity calibration and reliable operation.

Who is it suitable for and how to use it?

A carbon monoxide detector is essential for your home if you have a heating system, a kitchen fireplace or a garage. Families with small children, the elderly and people with respiratory conditions especially benefit from this protection. Easy installation without electrical work means you can mount it directly on the wall or place it in a convenient location. The constant LCD display allows you to quickly see the carbon monoxide level without complexity. Don't forget to test the button regularly, change the batteries regularly (about every 6 months) and keep it safe from moisture and excessive heat.

Buyer questions

Q: How quickly does this detector detect carbon monoxide?
The highly sensitive electrochemical sensor detects carbon monoxide instantly. At low levels of 50-100 PPM, it will alert within 80 minutes, and above 300 PPM – in just 3 minutes, guaranteeing timely and rapid protection.

Q: How long do these batteries last and how do I change them?
Two AA 1.5V batteries typically last 6-12 months, depending on usage. If you hear a beeping sound or the screen slows down, it's time to replace the batteries. Simply unscrew the back panel and remove the old batteries, then insert new ones.

Q: Can it work even when there is no electricity?
Yes! Since it is battery-powered, it works continuously even in the event of a power outage. This is very important, as more dangers can arise precisely when there is no power supply. Check the condition of the batteries regularly.

A carbon monoxide detector alarm is undoubtedly an important investment for your and your family's safety. It protects against the invisible and most dangerous gas that can be deadly. We recommend installing it in every apartment, house or garage that has a heating or combustion source. Especially suitable for people with children and the elderly.
