Analox

Analox make gas analysis and monitoring instruments, and are a familiar name to anyone filling or checking cylinders. Most of what we list here is the supporting range: replacement oxygen and helium sensors, an O2 cell, dome and flow adaptors, tubing, cases and the Sensor Saver, alongside the Carbon Monoxide CO Clear Analyser. Sensors are specific to the instrument they belong to, so check the manufacturer specification or ask us before ordering.

Who Analox are

Analox make gas analysis and monitoring instruments, used in diving, medical and industrial settings. In diving they are best known for oxygen and carbon monoxide analysers — the instruments used to check what is actually in a cylinder before anyone breathes it.

Built and manufactured in the UK, Analox dive analysers are designed to deliver reliable, repeatable readings in real-world diving environments. Whether analysing Nitrox, Trimix or checking compressor air quality, Analox instruments are used by dive centres, instructors and technical divers.

Clear displays, fast response times and dependable sensors make gas analysis straightforward. Analysing a fill is a standard part of pre-dive checks, letting divers confirm oxygen percentages and check for carbon monoxide contamination before a cylinder is used.

Here at Dive Rutland, we stock Analox because checking your own gas is worth doing. An analyser lets you verify the contents of a fill yourself, whether you are diving Nitrox recreationally or running trimix and CCR. It is one step in gas management rather than a substitute for the rest, so use it alongside your normal checks and your training.

What we stock from Analox

The Analox listing on this page is mostly the parts that keep an analyser working, rather than the analysers themselves. We carry replacement oxygen sensors for the O2EII and O2EII Pro and for the ATA, a replacement helium sensor, and an O2 cell for the portable oxygen monitor. Alongside those sit the dome adaptors — the O2EII Pro push-in domed adaptor with barbed spigot, and a spare dome adaptor — an ATA flow adaptor, a BCD low pressure inflator flow restrictor, replacement tubing by the metre, the Sensor Saver, and Peli cases for the ATA Trimix analyser and the O2EII Mini. The Carbon Monoxide CO Clear Analyser is the one complete instrument currently listed here.

Sensors and cells are matched to a particular instrument, and ordering the wrong one is an expensive way to find that out. Check the manufacturer specification for the analyser you own, or tell us the model and we will confirm the part before you buy.

Come and talk to us

If you are moving into Nitrox or Trimix, our guides to enriched air (Nitrox) and to Nitrox formulas are a good place to start. For the kit itself, come into the shop in Rutland or get in touch — and if there is an Analox item you cannot find on the page, ask, because we can often source it.

Frequently asked questions

Most of the Analox range listed here is spares and accessories for analysers already in service: replacement oxygen sensors for the O2EII and O2EII Pro and for the ATA, a replacement helium sensor, an O2 cell for the portable oxygen monitor, dome and flow adaptors, the Sensor Saver, replacement tubing, a BCD low pressure inflator flow restrictor, and Peli cases for the ATA Trimix analyser and the O2EII Mini. The Carbon Monoxide CO Clear Analyser is the complete instrument currently on the page.

Sensors and cells are specific to the instrument they are fitted to, so this is not one to order on a best guess. Check the manufacturer specification for your analyser, or tell us exactly which model you have and we will confirm the right part before you buy.

Quite possibly. If you cannot find the equipment you are looking for, please get in touch with the model and the part you need and we will let you know what we can source.

Yes. Come into the shop in Rutland and have a proper look at the kit in person. We are happy to talk through what you actually need for the diving and the gas filling you are doing.
