31 | DRÄGER GAS DETECTION
Dräger’s leading edge technology puts us on the forefront
of colorimetric detector tubes.
The world has relied on Dräger-Tubes
®
more than any other gas
and vapor measurement device to tell them when the air is safe
to breathe, to identify an unknown hazard, or to check on
process gases. For more than 70 years, Dräger has been the
leader in detector tube technology with more accurate measure-
ments, a wider range of gases and vapors measured, more
designs of tubes and more accessories to meet specific gas
and vapor measurement applications.
Though many Dräger-Tubes
®
require more than one pump
stroke, the sampling time is usually faster than competitive one-
stroke tubes. Not only do you get the benefit of quicker analysis,
the larger sample volume provides statistically better accuracy.
Once the sample is taken, the larger diameter Dräger-Tubes
®
and well-spaced graduation marks enable distinct and decisive
measurement readings.
Reagents used in the Dräger-Tubes
®
are chosen to provide not
only the most accurate, but also the most specific results. The
use of chemical pre-layers on many tubes (like benzene)
removes potentially interfering gases (e.g. aromatic hydrocar-
bons) so you only measure the targeted chemical, getting only
the results you want.
The cornerstone of the Dräger-Tube
®
system is the accuro
®
Pump. It draws a calibrated 100 ml sample of air through the
Dräger-Tube
®
with each stroke. The one-handed operation is
simple and allows you to reach places that a piston pump cannot
go. A built-in stroke counter tells you exactly how many strokes
have been taken. The visual end-of-stroke indicator signifies the
completion of each pump stroke.
DRÄGER-X-ACT

5000 AUTOMATIC TUBE PUMP
The handling of gases, vapors, and aerosols has never been
easier. The automatic tube pump, Dräger X-act 5000, directs the
air to be measured through the appropriate Dräger-Tube effort-
lessly. It is conveniently carried with one hand or using the
shoulder strap and is easily operated wearing heavy work
gloves. A simple and intuitive menu structure provides the user
efficient operation with just a few button presses.
SWIPING BARCODE LOADS MEASUREMENT DATA
Accuracy and reliability of measurement results is critical. A bar
code printed on the back label of a box of Dräger short-term
tubes contains all relevant measurement parameters. Simply
sliding the bar code over the bar code reader of the pump auto-
matically transfers the name of the substance to be measured,
the number of strokes, and the measuring range to the display.
REDUCED MEASUREMENT TIME
Less time spent measuring means reduced cost for your opera-
tions. The X-act 5000 presents a new concept that reduces the
average measurement time for certain Dräger-Tubes by 15 - 20%.
The key principle is the ability to provide the required flow
characteristics of the Dräger short-term tubes on the spot – no
manual calibration is necessary.
