Analox HYP Hyperbaric Portable O₂ Partial Pressure Analyzer

The Analox HYP Hyperbaric Oxygen Analyzer is a compact, portable hyperbaric O₂ analyzer designed specifically for monitoring oxygen partial pressure inside hyperbaric chambers and other pressurized environments. As a true hyperbaric chamber oxygen analyzer, the HYP measures ppO₂ directly rather than relying solely on oxygen percentage.

With an operating pressure range of 0.8 to 60 bar absolute, the HYP functions as a highly capable pressure-rated oxygen analyzer for hyperbaric chambers, diving bells, hyperbaric lifeboats, submarines, and other pressure-variable environments.

This portable oxygen analyzer measures oxygen partial pressure from 0 to 2.0 bar ppO₂, making it well suited for facilities that require an independent oxygen partial pressure analyzer or ppO₂ analyzer for chamber atmosphere monitoring. Its compact size, long battery life, and broad pressure rating also make it a practical hyperbaric oxygen monitor for professional and specialized chamber environments.

Purpose-Built Hyperbaric Oxygen Analyzer for Chamber Monitoring

  • Hyperbaric pressure rated: designed for operation from 0.8 to 60 bar absolute
  • Direct ppO₂ measurement: measures oxygen partial pressure from 0 to 2.0 bar
  • Hyperbaric chamber oxygen monitoring: designed specifically for chamber atmospheres and other pressurized environments
  • Portable oxygen analyzer: compact enough to hand carry or position within confined spaces
  • Long battery life: approximately 800 hours of continuous operation from a single 9V PP3 battery

Why Measure Oxygen Partial Pressure?

Oxygen concentration expressed as a percentage and oxygen partial pressure are related, but they are not the same measurement.

In a hyperbaric environment, total atmospheric pressure increases during compression. Even if the percentage of oxygen remains unchanged, its partial pressure increases because total atmospheric pressure has increased.

ppO₂ (bar) = Oxygen Percentage × Absolute Pressure (bar) ÷ 100

For example, an atmosphere containing approximately 20.9% oxygen at 1.0 bar absolute produces a ppO₂ of approximately 0.21 bar. The same approximately 20.9% oxygen atmosphere at 2.0 bar absolute produces a ppO₂ of approximately 0.42 bar.

Because the Analox HYP reports ppO₂ directly, this hyperbaric oxygen analyzer provides a measurement particularly relevant to pressurized chamber environments.

Important: The HYP displays partial pressure of oxygen, not oxygen percentage. If oxygen percentage is required, the user must also know the absolute atmospheric pressure and calculate the percentage accordingly.

Hyperbaric Applications

Hyperbaric Chamber Oxygen Monitoring
Independent partial-pressure oxygen monitoring within applicable hyperbaric chamber atmospheres.
Hyperbaric oxygen monitor
Portable oxygen monitoring for appropriate pressure-controlled chamber environments.
Diving bells
Designed for direct ppO₂ measurement within commercial diving and saturation environments.
Hyperbaric lifeboats
Compact design is suitable for confined hyperbaric rescue and evacuation environments.
Submarines
Partial-pressure oxygen monitoring where internal atmospheric pressure may differ from surface pressure.
Remote atmosphere sampling
Optional sampling accessories allow gas samples to be drawn from remote areas at the same pressure as the analyzer.

Hyperbaric Pressure Compatibility

The Analox HYP has a manufacturer-specified operating-pressure range of 0.8 to 60 bar absolute. This makes it a true pressure-rated hyperbaric O₂ analyzer and places the operating pressure of typical mild and moderate pressure hyperbaric chambers comfortably within its published range.

1.3 ATA chamber
Approx. 1.32 bar absolute

Operation & Monitoring

Startup
Switch the analyzer on and the oxygen measurement appears on the LCD within approximately one to two seconds
Local monitoring
Ambient gas diffuses directly into the oxygen sensor for measurement of the local chamber atmosphere
Remote monitoring
Optional sample-draw kit allows a remote atmosphere at the same pressure to be sampled
Low battery indication
Battery symbol appears when battery voltage approaches depletion
Avoid exhaling directly over the oxygen sensor while taking a measurement. Exhaled air has a lower oxygen concentration than the surrounding atmosphere and can temporarily alter the reading.

Calibration

Periodic calibration is required because electrochemical oxygen sensors gradually change output as the sensor is consumed over its operating life.

Fresh-air calibration
May be used where the analyzer will primarily measure air-equivalent atmospheres. Atmospheric pressure, temperature, and humidity should be considered.
Pure oxygen calibration
Manufacturer documentation identifies pure oxygen calibration as the preferred method where measurements will span the sensor's full range.
Calibration gas
Known calibration gas may be applied using the appropriate Analox flow adapter and regulator.
Reference analyzer
Calibration may also be checked against an appropriate reference analyzer when both instruments are exposed to the same gas.
Calibration adjustment
Recessed front-panel potentiometer provides manual calibration adjustment
Typical interval
Calibration frequency depends on accuracy requirements and application. Manufacturer documentation discusses six-month calibration as appropriate for many users, with more frequent checks in critical applications.

Humidity & Condensation

Hyperbaric environments can have elevated humidity and condensation. The HYP is designed with these conditions in mind.

Circuit protection
Circuit boards are specially coated to help protect against humidity and condensation
Sensor membrane
Hydrophobic membrane helps prevent liquid water from entering the oxygen sensor
Condensation management
Analyzer should be positioned so condensed water cannot accumulate over the sensor inlet
Recommended orientation
Vertical positioning helps allow collected moisture to drain away from the sensor inlet

Important Safety & Use Information

Pressure-change limitation: Do not subject the HYP analyzer to rapid compression or decompression. The manufacturer's specified maximum rate is less than 2 bar per minute. Do not transfer the analyzer through a medical lock or other system where pressure may change more rapidly.

The oxygen sensor is an electrochemical device containing a potassium hydroxide electrolyte. Damaged or leaking sensors should not be handled as normal components and must be managed according to manufacturer safety instructions.

This product is a hyperbaric atmospheric monitoring instrument. Users are responsible for establishing appropriate monitoring protocols, alarm thresholds, calibration intervals, and operating procedures for their specific hyperbaric installation.
