Analox have picked the We Remember Submariners charity to work with in 2023.

Analox are specialists in two distinct areas of the submarine atmosphere challenge.
We provide top class atmosphere monitoring systems, ranging from single gas atmosphere monitoring with the COSAMS unit (carbon monoxide atmosphere monitor system), to multi gas atmosphere monitoring with the AA (centralized Atmosphere Analyzer) and the DAMS (Distributed Atmosphere Monitoring System). Not forgetting the importance of a portable atmosphere monitor, the Sub Aspida, which provides portable carbon dioxide (CO2) and oxygen (O2) monitoring around the submarine.
We also support the submarine escape and rescue process with our top of the range dissub monitor – the Sub Mk3P, and with our fixed atmosphere monitoring system for submarine rescue vehicles (SRV’s) – the Sub MkIIIF.
We are proud to have been working in these areas for over 2 decades. Dedicated to working with the world’s submarine nations, learning and understanding the complex needs of your atmosphere monitoring requirements. Whether a boat is nuclear-powered or diesel propelled, we fine tune our systems to be responsive to the changes in temperature, pressure and humidity that occur inside your submarine.
The solutions to atmosphere monitoring and dissub support that Analox provides are second to none, and we aim to be the number one choice for submarine nations across the globe, ensuring the safety of every submariner is our number one priority.
‘Speaking to people in Analox you sense the passion and pride and where you have a proud workforce you have a good company. Analox have a good name in the submarine community - good service, reliable products and easy to work with.’

Submarine Atmosphere Monitoring
Having worked in partnership with Navies from around the world, Analox has an extensive knowledge of providing submarine atmosphere monitoring systems.
Submarine build times range from 5-10 years and they have an even longer lifecycle, with boats being in active service for over 30 years. The submarine atmosphere monitors that Analox build need to work just as effectively from when they were commissioned, to when the boat comes in from its final voyage. Analox ensures that the submarine that leaves the shipyard is the best in class in atmosphere monitoring until the day it comes home.
Analox’s brilliant engineering and manufacturing team design and make atmosphere monitors that offer modular configurations and bespoke systems. We design these systems to have a flexible architecture that meets all technical requirements from the boat manufacturer.

Centralized Atmosphere Analyzer
Capable of measuring up to 30 gasses, from up to 20 compartments via sample lines, the AA ensures crew safety throughout the submarine.
Utilizing 3 gas sensing modules including SIL2 O2, a functionally safe oxygen monitor, mass spectrometer and FTIR spectrometer, the AA monitors for;
Life support gasses which include oxygen (O2), carbon dioxide (CO2) and carbon monoxide (CO).
Fire gasses which are monitored include hydrogen cyanide (HCN) and nitrogen oxide (NO).
Carbon Monoxide Submarine Atmosphere Monitoring System
Carbon monoxide (CO) can be generated onboard a submarine in many different ways;
- routine operations such as cooking
- fumes of a diesel engine
- emergency operations such as an onboard fire incident
The COSAMS system offers continuous, real time monitoring of CO in the living accommodation and machinery spaces onboard a submarine. The system also has a 90 day data logging facility, allowing for records to be stored should they ever be needed.
CO can be incredibly dangerous, you cannot smell, taste or see it and the side effects of CO poisoning can be devastating. At 35 ppm, with exposure around 6-8 hours, you may see physical symptoms such as headache, fatigue, dizziness and/or nausea. At 200 ppm these symptoms can happen with only 2-3 hours of exposure. When you reach 400 ppm the symptoms will come within 1-2 hours of exposure, but fatality may occur around 3 hours. As the levels rise the time it takes for symptoms to show becomes less and less, and so does the time it takes for the exposure levels to become fatal. It is vital for submariners safety that there is continual monitoring of carbon monoxide onboard.
Distributed Atmosphere Monitoring System
The DAMS was created by Analox engineers to effectively monitor a range of gasses (up to 5) in multiple locations onboard a submarine that is more than 197ft (60m) long. It uses a PLC (programmable logic controller) in a centralized location to monitor all gasses simultaneously.
Each DAMS build uses various gas testing technologies to ensure that it meets the specifications for the submarine, including:
- gas filter correlation (GFC) to monitor carbon monoxide (CO)
- electrochemical for oxygen (O2) enrichment and depletion
- nondispersive infrared (NDIR) for carbon dioxide (CO2)
- R134a (refrigerants)
- catalytic bead technology for hydrogen (H2).
This system is proven in use and the Analox team are proud to be able to share (what little we can!) about the project. In 2018 Saab awarded Analox a contract to supply gas monitoring systems for the Blekinge-class (A26) next generation submarines. Read more about it here.
Throughout the project the Analox team was dedicated to providing exceptional service, working closely with Saab, engaging in detailed discussions to solve their specific challenges. We are proud to be part of the system spec, build and installation of that project.
A portable life line for atmospheric monitoring
The Sub Apida is designed to be a portable emergency backup to the main atmosphere monitoring system. The rugged and compact Sub Aspia offers both partial pressure oxygen and carbon dioxide monitoring in one. Meaning that in an emergency situation, you have your main gasses covered, ensuring the safety of the submariners in the area.
The Sub Apida may be small, but it was designed with the pressure sensitivities in mind. Both sensors in the monitor are pressure corrected, meaning that you get accurate readings over a pressure range of 700 – 1200MB.
Why should you use a specialist CO monitor like the COSAMS?
Off-the-shelf carbon monoxide detectors use standard electrochemical sensors that are extremely cross-sensitive to hydrogen. This means that they are not suitable for use on submarines as they will give out false CO readings. Using infra-red measuring techniques, instead of electrochemical sensors, Analox engineers managed to solve this problem, ensuring the safety of all submariners onboard.

We appreciate Analox’s ability and willingness to respond to our requirements. The service Analox provides is commendable.’

Sub Escape and Rescue
Analox is very proud to have worked with the Submarine Escape and Rescue community for over 20 years. We have built a reputation on providing solid gas analyzers in DISSUB situations which deliver reliable information allowing for trusted decisions to be made.
We regularly work with submarine nations from around the globe to understand what their specific requirements are to ensure we not only meet them, we exceed them!
Analox DISSUB products are used in annual submarine escape and rescue exercises, where submarine nations come together to test their DISSUB capabilities. Analox analyzers are fitted to the SRV’s and chambers completing these exercises and some can be seen in these NSRS Forces News videos:
The new generation of DISSUB monitors
The Sub Mk3P is the newest monitor in the Analox submarine escape and rescue product line. The Sub Mk3P is the next generation of DISSUB monitors, replacing the widely successful Sub MkIIP DISSUB analyzer in 2021. The Sub Mk3P monitors the partial pressure of oxygen (O2) and carbon dioxide (CO2) along with measuring the depth, pressure and battery life – all of which are key factors within a DISSUB emergency situation.
Meeting the NATO STANAG 1476:2014 (ANEP/MNEP-86) for submarines with an escape capability, the Sub Mk3P now allows for maintenance staff to perform routine servicing and sensor updates in the dockyard – saving costs and reducing downtime.
Designed in conjunction with submariners and submarine agencies, the unit’s highly recognizable orange housing ensures the Sub Mk3P is easy to identify in case of emergency.
An effective hyperbaric monitor for SRV’s
The Sub MkIIF provides hyperbaric monitoring systems for use within the submarine rescue vehicles (SRV) and surface decompression chambers. It is a fixed atmosphere monitoring system which not only provides the partial pressure O2 and CO2 readings but it also displays pressure, temperature and relative humidity of the environment too, giving you all the information you need when taking part in a rescue operation. The unit’s bright red illuminated display makes it simple to use and easy to read in tense DISSUB situations.
