Portable Carbon Monoxide Detector, Large Color Screen CO Detector, High Precision 3 in 1 Air Quality Monitor (CO Temperature Humidity), for Indoor, Outdoor, Car, and Camping etc

Key features

• ★【MINI 3-IN-1 CARBON MONOXIDE DETECTOR】The MINI 3-in-1 Carbon Monoxide detector can accurately detect the current CO concentration, temperature and humidity in the air. Let you understand the air quality more clearly and protect the health of you and your family. The mini lanyard design makes it so convenient to carry it or hang it anywhere.
• ★【HIGH-PRECISION】Use a high-precision electrochemical sensor and NDIR working method to ensure its accuracy. The CO accuracy is (±5PPM or ±5%), the temperature accuracy is (±1°C), and the humidity accuracy is (±2%RH). The data is refreshed every 2 seconds to know the air quality of the environment at any time. The multi-hole air duct design improves the air flow rate. Close to the sensor with multiple openings, the real-time air circulation and convection monitoring is more accurate.
• ★【4 AIR QUALITY INDICATORS & SOUND WARNING】According to the CO concentration data, the CO detector can display 4-segment graded color display. 0~50ppm (green/safe), 51~100ppm (yellow/needs attention), 101~200ppm (orange/warning), 201~1000ppm (red/dangerous). The default CO detector will warning when the CO concentration exceeds 50PPM. As the CO concentration PPM value increases, the frequency of the warning will also increase. Short press the "S" key to switch the buzzer on/off.
• ★【BUILT-IN BATTERY & BACKLIGHT DISPLAY】The MINI 3-in-1 CO detector has a built-in 1000mAh lithium battery, which can last for about 40 hours on standby when fully charged. Supports USB charging and power indicator. The 1.9" large TFT color backlit screen allows you to read easily even at night. The backlight function has 3 brightness levels, short press the "M" key to adjust the screen brightness mode (low, medium, high).
• ★【WIDELY APPLICATION】This portable MINI 3-in-1 carbon monoxide detector has the characteristics of wide measurement range, high measurement accuracy, small size, easy to carry, and easy to operate. Portable lanyard design can be widely used in outdoor and indoor activities, home, office, school, camping, picnic, boat, airplane, outdoor adventure, car and garage and other places.
