Equipped with a high-precision sensor that can detect from 0 PPM, it enables stable measurement even in Japan's rainy and humid environment.
When the CO concentration or duration exceeds a certain standard, it notifies you to ventilate with a buzzer sound and voice announcement, preventing the risk of carbon monoxide poisoning.
No wiring required; simply insert the included AA battery to start using it immediately. All operations such as power on/off, backlight brightness adjustment, memory check, operation check, and silent mode setting can be easily controlled with the buttons on hand.
Compact and easy to carry design. The lightweight body of only 70g fits neatly into your pocket, and with the included strap, it can be easily attached to a backpack. It is useful in various outdoor scenes such as autumn and winter camping and car camping.
