3-in-1 Carbon Monoxide Checker: Carbon Monoxide Concentration / Temperature / Humidity with Japanese Instruction Manual, Black

About This Product
[3-in-1 Multifunctional Carbon Monoxide Detector] This advanced model, while retaining the design of previous versions, accurately detects carbon monoxide levels, temperature, and humidity simultaneously. [Matte Finish for a Premium Feel, Stylish Whether Hung or Placed! Perfect for Gifts] Features a rugged and reliable black design that perfectly complements camping gear. It fits comfortably in your hand and blends seamlessly into outdoor scenes, whether hung or placed.
[Backlight Color Changes for Instant Danger Level Assessment] Not only numbers, but also backlight color changes: Green (50-100 PPM) → Yellow (101-200 PPM) → Red (201 PPM and above) allow for instant judgment of safety, caution, and danger. This user-friendly design ensures you can intuitively grasp the situation, even in dark tents or car interiors.
[Large Screen, Large Digits for Peace of Mind] Redesigned for 2025! The large screen and large digits make changes in carbon monoxide levels even easier to understand. While compact enough to fit in your palm, this carbon monoxide detector features a large 4.1cm diameter LCD display (approximately 380% larger than other products), allowing you to clearly check carbon monoxide levels even from a slight distance.
[Silent Button Design! No Disturbing Others] In addition to audible alarms, it also features a silent function. If you need to temporarily silence an alarm, press the silent button to pause it! For safety, the silent mode lasts for 5 minutes, during which time ventilation is required to bring the concentration back to a safe level. If the concentration does not return to a safe range within 5 minutes, the alarm will automatically reactivate. The silent design ensures alarms sound when needed and can be silenced when not, without disturbing others.
[Easy for Anyone! Use Anywhere] No wiring required; simply insert the included AA batteries. Convenient button operations allow for easy control of power on/off, backlight brightness adjustment, memory function checks, operation checks, and silent settings right at your fingertips.
[Energy-Saving Design! 24-Hour Continuous CO Monitoring] The high power consumption of commercially available Type-C rechargeable carbon monoxide detectors has been a challenge, requiring weekly charging. This battery-powered unit automatically turns off the backlight when there is no operation, switching to energy-saving mode. With a single battery change, it provides 30 days of continuous 24-hour CO monitoring, ensuring reliable safety management.
