Drager Tubes and Accuro Pump
 Most Trusted - Drager Tubes have been leading the
way in gas detection for over 60 years.
Widest Range - Over 200 different Drager Tubes
are available for measuring over 500
gases and vapors.
Hassle-Free Operation - No calibration, no lubrication, no special
maintenance. Always ready to go.
What is the Drager Tube system? -
Drager Tubes are glass vials filled
with a chemical reagent that reacts to a
specific chemical or family of chemicals.
A calibrated 100 ml sample of air
is drawn through the tube with the
Drager Accuro bellows pump.
If
the targeted chemical(s) is present the
reagent in the tube changes color and
the length of the color change typically
indicates the measured concentration.
The Drager Tube System is the
world’s most popular form of gas
detection..
Drager:
Leading Detection -
Ever since 1937 when we introduced
our first detector tube, Drager has
been the world leader in the analysis of
gases and vapors in the industrial
workplace. Over the years we have
developed more tubes and detection
devices for more applications than
anyone else!
Our leading edge technology
has kept us on the forefront
of colorimetric detector
tubes thus providing
the most accurate
and specific results
available.
Accurate -
Not all detector tubes are created
equal! Drager Tubes with the accuro
pump deliver the most accurate results.
Many Drager tubes offer a +/- 10%
standard deviation on the results.
This
is a result of our 60+ years of manufacturing
colorimetric tubes and the consistent
volume delivered by the bellows
pump design.
Quality assurance is
accomplished by individually calibrating
each batch of Drager Tubes.
Then
every batch is tested at regular intervals,
throughout the two year shelf life, to
guarantee accuracy over the entire life
of the tubes.
Easy To Read -
See the difference for yourself! The
wider diameter of the Drager Tubes
makes it easier to read.
Well-spaced
graduation marks enable distinct and
decisive measurement results. Color
changes to the reagents are well
defined over the entire length of
the stain.
Many Tubes offer a dual
calibrated scale so that you can
interpret the results without using
multiplication factors.

Fast -
One stroke tubes are not always
faster! Though many Drager Tubes
require more than one stroke, they
often provide measurement results
in less time. Not only do you get the
benefit of a quicker analysis; the
larger sample volume provides better
statistical accuracy.
Flexible -
Drager Tubes simply deliver more!
More gases and more measuring
ranges than any other manufacturer.
Drager offers over 200 tubes for
accurately measuring over 500 different
gases.
You can measure ambient
air for health and safety levels, optional
equipment allows you to measure
stack gases, motor vehicle exhaust
components, pressurized gas line
samples, compressed air contaminants,
and solvents in water samples. Other
specialized tubes measure over a
period of hours or a complete work
shift to indicate daily exposure levels.
Specitifc -
Reagents used in Drager Tubes are
chosen to provide not only the most
accurate, but also the most specific
results possible.
Our use of prelayers
on many tubes (like benzene) remove
other potential interfering gases (e.g.
aromatic hydrocarbons) so you measure
only the targeted chemical, getting only
the results you want.
This design
enables you to measure specific gases
in a complex ambient background
found in the measurement area.
Maintenance Free -
Drager has made gas detection easy.
Unlike a piston pump, the accuro pump
requires no lubrication.
The Accuro is
constructed of non-metallic, corrosion
resistant materials. It can’t be bent by
rough treatment and it withstands harsh
chemical environments.
Drager Tubes
are pre-calibrated for two years.
The only
requisite on Drager Tubes is that they
are stored out of direct sunlight and at a
temperature of less than 25°C (77°F).
Any temperature-controlled office meets
these conditions.
