Analox understands the critical importance of ensuring personnel are protected by appropriate and effective gas monitoring - especially in the diving market. Diver safety is our number one priority.

We are dedicated to offering you a personalized service ensuring a cradle to grave product life cycle tailored to suit your specific requirements.

The Design and Engineering teams continue to work tirelessly to ensure we are able to offer innovative equipment that is optimized to suit the environment and designed to be supported effectively throughout the platform’s life.
We specialize in the following areas of diving safety:

Saturation Diving

Whether you need to monitor hydrocarbons in a diving bell in 350 metres of sea water, monitor for heliox leaks in your saturation control room or monitor the chamber atmosphere hyperbarically or at the surface - we have a solution for you.

Contact us today and ensure IMCA compliance, minimal maintenance and minimal downtime with the air diving gas analysis experts.

Scuba Diving

Scuba divers, whether newly qualified or a veteran of the seas, need to know the breathing gas mix in their tanks to plan for a safe dive.

All Analox scuba analyzers are tried and tested, with some even being NATO coded. Long life with minimal running costs, Analox analyzers ensure nitrox, trimix and air divers are safe throughout the world.

Exceeding the conventional limits of scuba diving, technical diving (or Tec diving) pushes the boundaries of traditional scuba diving especially in depth and bottom time. Tec divers need equipment which can push the limits too - Analox thrives on developing and manufacturing such equipment.

Awareness of toxic gas contamination such as carbon monoxide in scuba diving is increasing. Although compliance checks are required every six months, what happens if there is a filter failure in-between? Analox offer gas analyzers to monitor for compressor contamination 24/7.

Commercial Diving

We created our first commercial diving monitor in the early 1980s, the Analox 100. We started to work with customers including Divex (now known as JFD), Advanced Marine and Amron... and the rest is history!

Our life-supporting oxygen, carbon dioxide, carbon monoxide and hydrocarbon analysers can be found on almost every diving system in the world. 

Our vast range of products includes the SDA range which monitors a wide range of gases and conditions, the IMCA compliant ADM Aspida and the Hyper-Gas MkII which checks the diving bell for potentially fatal hydrocarbons.

Military Diving

We have developed and supplied unrivalled gas analyzers for military diving for over thirty years. We offer the perfect choice of NATO-coded analyzers for air and saturation divers in a number of fields including: Police diving, Army diving and Navy diving as well as offering a bespoke design capability.

Get in touch today to see how we can help.

Air Diving

We understand that as a diving contractor you have lots to think about in order to get a tough job completed on time and as safely as possible. Analox is the number one choice in air diving.

We offer a wide range of products to keep the air you breathe safe, including the ACG+ breathing air monitor, ADM Aspida oxygen analyzer and the CO Clear carbon monoxide monitor.

We also offer innovative gas monitoring products to keep saturation divers safe.

Contact us today and ensure IMCA compliance, minimal maintenance and minimal downtime with the air diving gas analysis experts.


Analox can assist you with compliance to the new dive regulations of IOGP 411 diving practices using the ACG+:

  • Diver breathing gas from LP compressor, or any diver breathing from HP storage while any HP compressor is filling that HP storage receptacle
  • Real-time analysis will be afforded to each diver’s gas supply including the standby diver
  • Real-time analysis will test for oxygen, carbon monoxide, carbon dioxide
  • Real-time analysis will test for water vapor when risk assessment indicates the need
  • Display will be in dive control and should be fitted with audio visual warning

Oxygen Solutions

Breathing air is air that meets specified standards for contaminants. Pure oxygen (O2) is mainly used to speed the shallow decompression stops at the end of a military, commercial, or technical dive. Risk of acute oxygen (O2) toxicity increases rapidly at pressures greater than 6 metres sea water.

Analox offers a choice of wall mountable or portable solutions: 

Carbon Monoxide Solutions

Carbon monoxide (CO2) poisoning is a well recognized, but uncommon hazard of sport and inshore diving, which occurs either as a result of a faulty air compressor or from air contamination by the exhaust of nearby petrol engines.

Analox offers a choice of wall mountable or portable solutions:

Nitrox Solution

It is this higher percentage of oxygen (O2), and the proportionately lower percentage of nitrogen, that allows divers to lengthen no-decompression limits, shorten surface intervals and get an added safety buffer for decompression sickness in certain diving circumstances.

Analox offers a choice of portable solutions:

Hydrocarbons Solution

We are the only company in the world that has achieved how to monitor hydrocarbons in a hyperbaric environment.

Analox offers a the Hyper-Gas MKII as the solution:

Carbon Dioxide Solution

Multi-Gas Solutions

If you are using multiple gases or are looking for an analyzer, look no further.

Fun Fact

Once you get below 10 metres depth, you can't see red or yellow!
