Divesoft He/O2 Analyzer Kit - Diver Max
Hi-tech analyzer for measuring nitrox and trimix gases. After inserting the analyzer adapter (included) to a bottle valve with a breathing mixture, the content of both oxygen and helium is shown as percentages directly on the display at the same time.
- Standard flow limiter for all valves.
- Worldwide Power Supply
- Hard and watertight Case
- Connection hose
- Ohmmeter plug-in
- Voltmeter plug-in
- Measuring cables
This trimx analyser reports "FOUL AIR" if the oxygen, nitrogen and helium can not be calculated due to contamination which is a major safety advantage over any other analyser.
- OLED Display
- Analyzer has built in Gas Mixing Calculator
Continous flow mixture measurement with Hi/Lo alarms for He and O2
new electronics with lower energy usage
- Gas purity option serves for gas purity measuring.
It is primary suited for argon, but after readjustment of the values it is possible to use for several different gases.
It is also possible to detect ratio of two gases with different speed of sound. For example: helium/nitrogen, helium/argon, hydrogen/nitrogen, hydrogen/argon and many more.
A standard electrochemical sensor (R-17D) normally used in analyzers for diving is used to determine the oxygen content. The helium content is determined on the basis of measuring the speed of sound in the analyzed mixture.
The speed of sound depends on the content of helium and oxygen, and on the temperature of the mixture. The dependence of the speed of sound on pressure is marginal and can be ignored under normal atmospheric pressure. At 0°C the speed of sound is approximately 970 m/s in pure helium, 330 m/s in air, and 315 m/s in pure oxygen. Raising the temperature by one degree raises the speed of sound by approximately 0.175%. The speed of sound in the mixture is described as a non-linear equation of temperature, oxygen content and helium content.
The speed of sound is measured directly as the time it takes for an acoustic impulse to travel between two microphones. This measurement is taken alternately in both directions to eliminate the influence of the gas flow-rate.
