【Carbon Monoxide Checker】Prepare for invisible dangers! 3-in-1 sensor that also measures temperature and humidity
What you need to be careful of during fall and winter camping is carbon monoxide poisoning. Because it is colorless and odorless, a carbon monoxide alarm is necessary when using a stove inside a sealed tent. If you're buying now, the convenient 3-in-1 sensor is recommended!
The 3-in-1 model features waterproof and dustproof functions, and is equipped with a thermometer and hygrometer
The "NESTOUT Carbon Monoxide Alarm," developed specifically for outdoor scenes such as camping. Considering outdoor use, it uses an LCD with a highly visible backlight. It allows you to instantly check information about carbon monoxide and other gases, even in night or bright sunlight conditions.
For detecting colorless and odorless carbon monoxide, which is often hard to notice, a high-performance sensor from Figaro Engineering is used. It guards against false alarms caused by humidity changes or other gases, while maintaining high stability in detecting carbon monoxide.
Thanks to a high-precision correction function that adjusts for temperature, aging, and battery voltage fluctuations, accurate readings can be achieved even in harsh outdoor conditions. It also features a self-diagnostic function that alerts you in case a sensor malfunction is detected. An environment where you can use it with peace of mind is provided (in some cases, the self-diagnostic function may not be able to detect the nature of the malfunction).
