Specifications:

• High sensitivity and fast alarm: The carbon monoxide detector has a built-in advanced high-sensitivity electrochemical CO sensor, which provides a high-precision alarm and fast and accurate detection of carbon monoxide levels. When the detected carbon monoxide concentration exceeds the normal level, it will sound an alarm exceeding 85 decibels.
• Alarm standard：When the detected carbon monoxide concentration exceeds 30ppm, the alarm screen will light up and display the concentration of carbon monoxide in the air. When the concentration reaches 100ppm, the detector will immediately send out an alarm sound exceeding 85dB, and flash the red LED light to alarm!
• LED indicator and LCD digital display:LCD display will show CO concentration immediately when CO gas is detected.LED indicator clearly informs the working status of CO alarm detector: green LED indicates normal operation (flashing every 60 seconds), yellow LED indicates fault, red LED indicates alarm status.
• Battery powered easy to install:Portable size, you can install it in your house, car, or take it with you when you travel or camping.
