Accurate and easy to use, the Drager Pac 3500 is ideal for
industrial personal monitoring applications. Providing quick
detection of carbon monoxide, hydrogen sulfide or oxygen, this
robust single gas detector has a lifetime of 2 years and is made
specifically to fit industrial safety requirements.
SMALL AND ROBUST HOUSING
Drager Pac 3500’s impact-resistant housing
features a protective rubber coating
and is impervious to corrosive chemicals.
Drager Pac 3500 meets the requirements
of IP 65 to ensure operation even
when projected with water. A crocodile
clip securely fastens the instrument to
the user’s clothing and can be adjusted
to allow for individual preferences.
To ensure continuous operation even when
the gas inlet is accidentally covered, the
instrument’s sensor has been carefully
positioned to allow gas intake from both
the top and the front of the device.
MINIATURE SENSOR TECHNOLOGY
Incorporating the latest miniature Drager
XXS sensor technology, the Drager Pac
3500 has been specifically developed for
use in personal monitoring and handheld
applications. The robust and pressure
compensated sensors reliably detect
CO, H2S and O2 and because of the very
low sensitivity drift, the Drager Pac 3500
can be used over a 2 year period without
Easily seen at a glance, the large display
shows both the gas concentration and
the measurement unit. Alternatively, the
instrument can be configured to show
only the gas detected. The concentration
is then only displayed when the set alarm
level has been exceeded.
Language-free to avoid any misunderstanding,
this continuous numeric display
can also be back-lit to improve readability
in darker conditions. Colored labels are
also available to distinguish the instrument
at a distance.
ALARMS AND WARNINGS
In addition to a vibrating alarm, the Drager
Pac 3500 emits an audible, multi-tone signal
and a clear, 360° visual alarm via bright,
flashing LEDs at the top and base of the
instrument. The alarm threshold levels can
be individually adjusted to adhere to company
policy or standardized with the use of
Complete with an infrared interface and
able to store up to 60 events with dates and times, the Drager Pac 3500 can be
easily linked to a PC via a connecting
cradle. This means that significant events
such as switching on or off, gas and battery
alarms, error codes, configuration changes,
fresh air calibrations and bump tests can
be downloaded, printed and stored centrally
for future reference or reporting purposes.
QUICK AND RELIABLE BUMP TESTING
Bump or function tests are necessary to
check if the instruments are functioning
correctly. Most national regulations require
users to test equipment against a known
gas concentration on a regular basis.
Featuring adjustable bump test and calibration
intervals, the Drager Pac 3500
alerts the user when bump tests or calibration
are required. If this warning is
ignored or a test is unsuccessful, the
instrument automatically displays an “out
of order” error message.
Performed together with the Drager
Bump Test Station, a typical bump test
takes between 8 and 15 seconds and
requires no additional power so that the
test can be performed on site. Each test
result is automatically stored in the event
logger and, should hard copies be required,
an optional mobile printer can be used.
If necessary, a fresh air calibration can
be carried out during the start-up sequence.
All other calibration options are only
accessible via a password-protected menu.
