What Is Carbon Monoxide?
Carbon monoxide (CO), also called carbonous oxide, is a colorless, odorless, and tasteless gas that is slightly lighter than air. It is highly toxic to humans and animals in higher quantities, although it is also produced in normal animal metabolism in low quantities, and is thought to have some normal biological functions.
Carbon monoxide consists of one carbon atom and one oxygen atom, connected by a triple bond that consists of two covalent bonds as well as one dative covalent bond. It is the simplest oxocarbon. In coordination complexes the carbon monoxide ligand is called carbonyl.
Carbon monoxide is produced from the partial oxidation of carbon-containing compounds; it forms when there is not enough oxygen to produce carbon dioxide (CO2), such as when operating a stove or an internal combustion engine in an enclosed space. In the presence of oxygen, carbon monoxide burns with a blue flame, producing carbon dioxide.
How it Works
CO-PRO is a quick and effective way to detect the presence of Carbon Monoxide (CO) in breathing air.
If the air is contaminated by CO, the Capsule within the balloon will change color.
That's all there is to it.* CO-PRO is intended only as a detector of carbon monoxide and is not a substitute for proper testing or inspection of breathing air.
* Not intended for Trimix gas.
Follow these easy steps.
1. Remove Sensor Button from its package.
2. Insert Sensor Button into the balloon.
3. Stretch the mouth of the balloon over the scuba valve.
4. Inflate the balloon slowly until the Sensor Button is visible. (approximately 7 inches in diameter)
5. Remove balloon and tie it off. (can be used multiple times or until CO is detected)
6. Wait 5 to 10 minutes for a color change. (See chart below for color change)
How many times can I use the CO-Pro?
It can be used multiple times or until carbon monoxide is detected. Once the package is opened, the CO-Pro should not be exposed to atmospheric conditions longer than eight hours. Poor atmospheric conditions (carbon monoxide, moisture, etc..) can greatly decrease the sensor's ability to detect.
At what ppm does the CO-Pro start to indicate?
The CO-Pro can indicate carbon monoxide as low as 5ppm.
How long does it take for the CO-Pro to indicate carbon monoxide?
It all depends on the concentration level. The higher the concentration, the faster it will indicate.
What is the shelf life of the CO-Pro?
Each package has an expiration date stamped on it. Approximately 2 years.
