The Divex G11-4 Hyperbaric Analyser measures partial pressure of oxygen and is designed for internal diving chamber, bell or other hyperbaric use. The Divex G21-2 monitors oxygen levels ranging from 0.00 to 19.99% and 00.0 to 100%. The Divex G22 Oxygen Analyser is a rack mounted instrument which provides continuous digital display of oxygen concentration in the gas sample presented to the surface of the sensor unit. The Divex G30 is extremely popular with commercial diving contractors worldwide as it is designed for monitoring carbon dioxide levels in diving decompression chambers. This rack mounted analyser provides a constant display of parts per million CO2 within 2% accuracy.

Contaminated Water Diving System

The “Dirty Harry” Contaminated Water Diving System is designed to provide a safe and efficient surface supplied system which minimises the risk of contact between the diver and the water in which he is diving. A closed circuit breathing system exhausts the diver's gas to the atmosphere at the surface rather than to the water.

Helmets & Masks


The AH5 is the lightweight successor to the Divex free-flow AH3 and AH4 helmets. It is designed to be used either fitted with its own neck-seal, or locked directly into a dry suit. Because it combines many of the advantages of both the traditional hard-hat helmet and the modern diving mask, the AH5 is recommended for tasks as diverse as heavy construction, mobile inspection and protracted dives in cold and polluted waters. With an increased over-pressure option plus extra weights the helmet can be used in nuclear reactor fuel ponds. If the suit should leak then the increased over-pressure results in air escaping out of the suit and not water leaking inwards. Although the AH5 is light, it is extremely strong. The monocoque head shell is made from hand-laid impact resistant glass fibre.
