50ppm: Maximum concentration that healthy adults can tolerate in eight hours
200ppm: slight headache after 2-3 hours
400ppm: Forehead pain within 1-2 hours: Life threatening after 3 hours
800ppm: 45 minutes, dazzling, nausea, cramps: loss of consciousness after 2 hours
1600ppm: headache, dizziness, nausea within 20 minutes: death within 1 hour
3200ppm: headache, dizziness, nausea within 5-10 minutes: death within 25-30 minutes
6400ppm: headache, dizziness, nausea within 1-2 minutes: death within 10-15 minutes
12800ppm: death within 1-3 minutes
Note: The symptoms of CO poisoning in the table above are for healthy adults and for high-risk and vulnerable people. Its response is different. Staying in a carbon monoxide environment containing a concentration of 50 ppm for more than eight hours may also cause carbon monoxide poisoning. The electrochemical carbon monoxide detector is dedicated to the detection of CO gas. CO gas is a colorless, odorless, non-irritating, toxic gas that cannot be sensed by the senses. It is mostly generated in the combustion environment of fireplaces, wood, coal, electric heaters and water heaters that lack oxygen.
Therefore, in order to ensure the safety of home life, it is recommended to install carbon monoxide alarm detectors in kitchens, bathrooms, living rooms, bedrooms, garages and other places where there is no air circulation for a long time. The product is powered by a DC 9V battery. When the detector alarms, it will give an alarm sound of ≥85dB, and the red alarm light will flash at the same time. During normal operation, the green indicator flashes once every 30 seconds. The detector has a low voltage alarm function and a key test function. Press the test button on the panel for 1 second to sound an alarm and the red indicator light will flash. The detector uses low power consumption technology, and the theoretical battery is replaced once a year. Sensor fault detection function: yellow LED flashes and buzzer is displayed at the same time-(fault can be automatically restored).
> Working voltage: 9V battery
> Static current: ≤15 ~ 35uA
> Alarm current: ≤10 ~ 30mA
> Alarm concentration:
When the concentration is 30ppm, the alarm will alarm within 120 minutes;
