2.0 System Description
The Pro HE
TM
Helium Analyzer measures helium (He) levels in gases in the range of 0 to 100%
of volume with a.1% resolution. It can be used to measure the He content in all breathing gas
mixes. The Analyzer is designed to verify helium concentration in stored gas cylinders as well
as to monitor continuous flow of gas from a compressor. The Analyzer is a moisture and impact
resistant unit 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 battery powered or 110/230V and
includes an internally mounted sensor with audible &
visual alarm. The water-resistant case includes a
digital display and controls that are environmentally
sealed
The Analyzer uses a Flow Adapter Cap and Flexible
tubing to deliver sample gas to the Sensor.
Pressurized gases must be regulated to avoid damage
to the analyzer. Use of this Analyzer in a hyperbaric
chamber will void the owner’s warranty.
The Analyzer is self calibrating and ready for use after
powering on. Certified calibration gas should be used
periodically to confirm the accuracy of the analyzer
sensor and electronics are working properly.
This analyzer is designed for use at atmospheric pressures only. It is not designed for
exposures 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 is a rugged instrument, careless handling or abuse may result in
damage to the Analyzer resulting in inaccurate gas analysis. Inaccurate gas analysis can
lead to serious personal injury or death.
Extreme Helium exposure levels directed at the Analyzer sensor may damage the sensor.
