Carbon monoxide (CO) gas is formed from the combination of a carbon atom with an oxygen atom. Not only flammable, it is also very hazardous since it is very toxic and odorless. It cannot sustain life and is produced, among other things, from incomplete combustion due to lack of oxygen. It can therefore cause domestic accidents if heating systems are poorly maintained. It is produced on a large scale in industry, in combination with hydrogen, by reforming hydrocarbons, generally natural gas. It is used in large quantities to produce various intermediary organic chemicals, such as acetic acids, isocyanates, formic acid, and also certain polymers such as polycarbonates and polyketones.
The current Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for carbon monoxide is 50 parts per million (ppm) parts of air (55 milligrams per cubic meter (mg/m(3)) as an 8-hour time-weighted average (TWA) concentration.
CO is the most common gas, which is detected for leakage, in all sorts of industries. Leakages from combustion devices like boilers, gas turbines, furnaces, heaters, incinerators, and from gas pipelines, and vessels, are detected using handheld, and fixed gas detection systems.
Testo 317-3 is one of the commonly used gas detectors in the industry. Its important to identify and stop a CO leakage at the earliest, and hence, fast and accurate detection of the leaked gas is of primary importance. Testo 317-3 was developed to detect and measure CO gas absolutely reliably, and in case of danger to provide warning without delay.
The testo 317-3 is absolutely insensitive to temperature fluctuations as well as humidity, and identifies malfunctions on a burner quickly and securely. It reports just as reliably when dangerous CO concentrations form in pellet stores - optically as well as audibly. You can evaluate the danger quickly and precisely thanks to the ppm display.
