What does a gas analyzer do?

Gas analyzers are analytical devices that measure the concentration or quality of a specific gaseous compound within a mixture of multiple gases.

What gas do divers use?

Deep sea divers normally breathe a mixture of nitrogen and oxygen, called nitrox or EAN (Enriched Air Nitrox).

Are gases in scuba tanks are harmful to divers?

Mixed gases are breathed by divers in both open circuit SCUBA and rebreather equipment. Generally using mixed gases reduces the diver’s exposure to the toxic and narcotic effects of elevated partial pressures of nitrogen and oxygen while managing their exposure to decompression illness and preventing hypoxia.

What gases are involved in scuba diving?

A range of gas mixtures, involving various proportions of nitrogen, oxygen and helium, are used to reduce the effects of nitrogen narcosis, increase dive time and reduce decompression. Breathing the right gas at the right depth is essential to avoid problems.

What would an exhaust gas analyzers be used for?

An exhaust gas analyser or exhaust carbon monoxide (CO) analyser is an instrument for the measurement of carbon monoxide among other gases in the exhaust, caused by an incorrect combustion, the Lambda coefficient measurement is the most common.

How deep can mixed gas divers go?

Choice of mixture composition Safe limits for mix of gases in trimix are generally accepted to be a maximum partial pressure of oxygen (PO2—see Dalton’s law) of 1.0 to 1.6 bar and maximum equivalent narcotic depth of 30 to 50 m (100 to 160 ft).

How deep can you dive with air?

130 feet
There are depth limitations too, as nitrogen becomes narcotic the deeper you go. This becomes increasingly debilitating, so the maximum depth for recreational diving is 130 feet (40 m). Air itself becomes toxic as we go beyond 184 feet (56 m). Best used for: All recreational diving down to 130 feet (40 m).

What happens if you breathe pure oxygen?

Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can’t see properly, and your lungs, so you can’t breathe normally. So breathing pure oxygen is quite dangerous.

Why are scuba tanks pure oxygen?

Think again. Pure and high percentage mixes of oxygen (such as nitrox or trimix) are used by trained technical and recreational divers to extend bottom times and to speed decompression. On the surface, pure oxygen is recommended first aid for the majority of diving injuries.

What is in an oxygen tank for scuba diving?

A common mixture is 21/35, which has 21 percent oxygen, 35 percent helium and 44 percent nitrogen. Another common mixture is 18/45, with 18 percent oxygen and 45 percent helium. These mixtures allow technical divers to hang around at up to 197 feet (60 m) — and actually remember their dive.
