2.0System Description
The Pro He-O2 Helium & Oxygen Analyzer measures Helium (He) and Oxygen (O2) levels in
gasses in the range of 0 to 100% of volume with a .1% resolution. It can be used to measure the
He and O2content in all breathing gas mixes. The Analyzer is designed to verify Helium &
Oxygen concentration in stored gas cylinders, as well as monitor a continuous flow of gas. The
Analyzer is compatible with outdoor and marine environments.
Helium is a colorless, odorless, tasteless gas that will not support life.
Exposure to Helium can lead to unconsciousness and death.
The Analyzer is powered by a rechargeable Lithium
Polymer battery. A 110/230 V charger is supplied with
the unit. Also included are two internally mounted
sensors.
The Analyzer uses a flexible tubing to deliver sample
gas to the Sensors. Pressurized gases must be
regulated to .5-1.0 L/min in order to avoid damage to
the analyzer. Use of this Analyzer in a hyperbaric
chamber will void the owner’s warranty.
Certified calibration gas should be used periodically to
confirm the accuracy of the analyzer and that the
sensor and electronics are working properly.
This analyzer is designed for use at atmospheric pressures only. It is not designed for
exposure in a hyperbaric chamber. Use of this analyzer in a hyperbaric chamber will
result in incorrect readings and may damage the unit.
Although the Analyzer has been designed to handle rugged environments, careless
handling or abuse may result in damage to the unit and this may result in inaccurate gas
analysis. Inaccurate gas analysis can lead to serious personal injury or death.
High Pressure Gas directed at the Analyzer may damage the sensors.
The Analyzer is provided in a water-resistant case. However, the electronics inside are
not water resistant. The Lithium Polymer battery can heat up and cause a fire if exposed
to water. Do not allow water to enter the Analyzer case.
