NITROX/TRIMIX
Alpha 1 Oxygen Analyser
Hand held oxygen analyser ideal for analysing oxygen content in any location. The robust metal housing which includes the oxygen sensor and the water-proof (IP65) construction make this analyser a first choice for diving schools, instructors and divers alike.
The Alpha 1 is standard with the pro panel and Mixmaster panels and available as an option with the classic panel.
Features
- Cast metal housing sealed with rubber gaskets, IP65 protection
- Large stainless steel eye for lanyard/hook
- Fine calibration with hand wheel, secondary calibration inside
- User replaceable 9V battery (display goes faint to indicate battery change due)
- Sensor inlet sealed with screw cap and O Ring for water protection and conserving sensor life
- User replaceable sensor, expected life approx. 3 years
- Measuring range 1-100% oxygen
- 0.1% accuracy
Gas Blending Panels
Using the partial pressure method, Nitrox and/or Trimix can be mixed and filled safely, easily and accurately using our Pro or Classic filling panels. The panels are tested and certified for 100% oxygen and/or helium mixing for all your breathing gas requirements. Practical valve and gauge layout makes operation easy to learn and use.

Nitrox Membran Systems
Nitrox membrane systems are based around a special semi-permeable „filter“ called a membrane. The membrane is fed with very clean, low pressure air. The air is separated between oxygen and nitrogen within the membrane leaving a higher percentage of oxygen (> 28 – 40%) in the gas that exits the sides of the membrane, and a higher percentage of nitrogen (> 90 – 99%) exiting the top of the membrane. The capacity of the membrane is the amount of nitrox produced. This is then compressed in a suitable HP compressor, the quantity of nitrox must be higher than the delivery rate of the HP compressor due to some loss within the HP compressor.
The membrane therefore has a degree of waste (the nitrogen) so that the amount of air entering the membrane is considerably higher than the nitrox exiting the membrane. This air requirement is the most important factor when sizing either the high pressure storage or the low pressure compressor that feeds the membrane and increases drastically with an increase in oxygen percentage of the nitrox.
L&W membranes are available in two sizes S & L. The L membranes can also be mounted in parallel to produce even higher quantities of nitrox if required (> 800 litre/min).
Mixmaster HP
Available in 2 versions, large and small. The Mixmaster HP panels have an HP breathing air inlet with isolation valve and pressure reducer that safely reduces the HP supply down to the desired LP inlet pressure. The HP version has a large filter for air conditioning to ensure that the membrane is supplied with oil-free air, this reduces the risk of membrane contamination. The HP solution has the advantage of using pure breathing air to feed the membrane, this reduces the risk of membrane contamination.
The investment cost are lower than a LP solution, but the running costs are higher. 2 HP compressors offer the ideal solution with redundancy for professional diving centres. If only 1 HP compressor is available then a higher capacity storage will be necessary.
