About this item

• 【Multi-Function Detector】: The 3-in-1 carbon monoxide detectors have carbon monoxide detection function（0 to 1000PPM）, temperature(32 to 122℉), and humidity (0% to 100%RH) detection functions to protect your safety in all directions. The handheld and portable design is suitable for camping, home, travel, etc.
• 【Professional Sensor & Sensitive Response】:Carbon monoxide detector equipped with imported electrochemical sensor, quickly detects CO levels of 0-1000 ppm. Please note that you need to aim at the top when detecting gas. The side of the detection port will block the gas from entering, reducing the detection sensitivity of the sensor.
• 【Ultra-Long Battery Life & Outdoor Portability】: The package contains 3 AAA batteries, with a usage time of up to 120 hours, suitable for long-term outdoor use and other scenarios; high-quality ABS + PC material and non-slip edge texture, small shape and easy to hold, back buckle for easy carrying.
• 【Dual Alarm】:Carbon monoxide alarm will be triggered when the CO gas ≥150PPM. Emit alarm sound (alarm sound decibel ≥75), accompanied by strong vibration , you can be reminded in a noisy environment and protect your life safety; color LCD display, HD screen, can read clearly even at night.
• 【Note】: Please tear off the protective film before use, the electrochemical sensor is located in the small hole at the top of the detection port. When detecting gas, it needs to be aimed at the head. Please do not use the side of the detection port for detection, because the filter on the side of the detection port will block the gas from entering and reduce the detection sensitivity of the sensor.
