Carbon monoxide (CO) is produced naturally in trace amounts by the partial oxidation of methane in the atmosphere, volcanoes and forest fires. Dangerous levels of CO are produced by oxygen-starved combustion in improperly ventilated fuel-burning appliances such as oil and gas furnaces, gas water heaters, gas ovens, gas or kerosene space heaters, fire places and wood stoves.
We offer both CO sensors as well as personal safety monitoring devices.
CO Recommended Levels
0.1 ppm is the current average CO level on the planet
OSHA limits long-term workplace exposure levels to 50 ppm (parts per million)
Symptoms of mild CO poisoning include headaches and dizziness at concentrations less than 100 ppm
Concentrations as low as 700 ppm can be life-threatening
Note that electrochemical sensors must be stored in sealed containers between 37° and 68°F (3° and 20°C) for long life. Some suppliers do not do this. Our sensors are stored in sealed containers in a refrigerator at 40°F (4.4°C) to provide the longest sensor lifespan when it is delivered to you.
