Travel Portable Carbon Monoxide Detector, 3 in 1 CO Monitor (Temperature, Humidity and Carbon Monoxide), with Alarm & Lanyard and Bracket Design for Indoor Outdoor Camping Travel RV Hotel - Model HD10 NEW RETAIL

• 【3-in-1 Multifunctional CO Detector】portable carbon monoxide detectors are not only capable of detecting CO levels, but also display and monitoring temperature and humidity, and data is displayed on a 2.1'' HD screen clearly. With a 2s refresh rate sensor , we can quickly determine the surrounding CO value and overall air quality, real-time knowing the environment is safe or not.
• 【Portable and Compact Design】co detector unit is with mini pocket and handhold size, its dimension is ‎2.5 x 2.5 x 0.79inches, can be put in pocket easily. Also, it has 8.7ins lanyard, foldable kickstand, can be hanging and stand-up.

• 【Newly Upgraded Electrochemical Sensor】Built-in new upgraded sensor makes it more accurated and longlasting detect carbon monoxide, which refreshes each 2s, to detect surrounding co value quickly. CO range: 0 to 999PPM; Humidity range: 0% to 95%RH; Temperature range: 14℉ to 122℉. The cycle alarm works when the CO is over 50ppm: 50-200ppm: 5 times alert in 3 mins, 200ppm upper: continuously alert. Real time detecting the CO is so important for us to avoid any CO harm.
• 【New Power Saving Mode Extends Battery Life】Built-in 1000 mAh battery provides up to 120 hours of use and can be fully charged in 3-4 hours by Type-C plug.
• 【Easy to Use】 gas detector air quality monitor is easy to operate. 1. Press "☀️" button to adjust screen brightness, there is 3 brightness modes. 2. Short press "⭕", change °F to ℃, long press "⭕" to switch on/off. 3. Press "🔊", to switch alarm beep on/off. The beep will be activated when co value over 50PPM. It can be shut down by pressing "🔊". But when it over 200PPM, the alarm always issued automatically, can't be shut down by manual, until it less than 200PPM.
• 【How to Test It ?】 Carbon monoxide is generated in incomplete combustion and dense smoke. We can take it close to a cigarette or burning paper that produces thick smoke. The CO concentration will change and show on the screen. Don't test it by car exhaust or airy place, too low CO consentration can't not trigger sensor to work.
