Best for measuring the indoor CO/CO2 concentration
Air Checker CO/CO2 Meter MB-350, measures and indicates carbon monoxide(CO), carbon dioxide(CO2), temperature, humidity. This instrument helps you to stay conscious of the air around you and maintain a healthy indoor environment. We recommend that this instrument should be used in greenhouses and other plant facilities to monitor the carbon monoxide or the carbon dioxide level.
CO concentration and the poisoning symptom
200ppm --- Slight headache within 2-3 hours
400ppm --- Frontal headache in 1-2 hours
800ppm --- Dizziness, nausea, and convulsions within 45 minute; insensible within 2 hours
1600ppm --- Headache, increased heart rate, dizziness, and nausea within 20 min; death in less than 2 hours
3200ppm --- Headache, dizziness and nausea in 5 to 10 minutes. Death within 30 minutes.
6400ppm --- Headache and dizziness in 1 to 2 minutes. Convulsions, respiratory arrest, and death in less than 10-15 minutes.
12800ppm --- Death in less than 3 minutes
This instrument helps you to measure carbon monoxide(CO), carbon dioxide(CO2), temperature, humidity to maintain the healthy indoor environment. Our own developed, NDIR (nondispersive infrared absorption system) sensor is used for CO2 measurement and electrochemical sensor is used for CO measurement.
We support the efficient ventilation and temperature adjustment for the better living environment
