[3-in-1 Multifunctional Carbon Monoxide Checker]

[High Precision & Instant Detection! Ideal for Japanese Outdoors] Equipped with a high-precision sensor capable of detecting from 0 PPM, it stably measures even in Japan's outdoor environments, which are often rainy and humid. The 3D multi-faceted air intake amplifies airflow, accurately capturing even slight changes in carbon monoxide concentration and displaying them on the screen in just 0.5 seconds. This safe design combines accuracy and speed, protecting you and your loved ones from the invisible, inaudible, and odorless danger of carbon monoxide. It's an essential safety item for camping, car camping, and disaster preparedness.

[Check Danger Level at a Glance] Not only numbers but also backlight color changes: Green (50-100 PPM) → Yellow (101-200 PPM) → Red (201 PPM or higher) allow for instant judgment of safety, caution, and danger. Even in dark tents or cars, you can intuitively grasp the situation with this reassuring design. [Large Screen & Large Characters! Safe Confirmation] 2025 New Design! With a large screen and large characters, changes in carbon monoxide concentration are even easier to understand. Although the carbon monoxide checker is palm-sized, it features a large 4.1cm diameter LCD display (approximately 380% larger than other products), allowing you to clearly check the carbon monoxide concentration even from a distance. The most dangerous CO concentrations are displayed largest on the screen, and temperature/humidity information can also be checked simultaneously, providing peace of mind in various environments such as tents and cars.

[85dB Loud Alarm + Japanese Voice for Instant Danger Notification] When CO concentration or exposure time exceeds a certain standard, it prompts ventilation with a buzzer and voice announcement, preventing the risk of poisoning. Sleep soundly! The loud alarm ensures you won't miss a notification of carbon monoxide danger! [Silent Button Design!] In addition to sounding the alarm, it also has a silent function. If you need to temporarily stop the alarm, press the silent button to pause it! For safety, the silent duration is set to 5 minutes, during which time you must ventilate and lower the concentration to a safe level.
