31 | DRÄGER GAS DETECTION
Accurate gas measurements are made easier with the Dräger-CMS
®
. This new
generation spot-check detection device is literally as easy as 1-2-3 to operate.
Simply insert one of the over 50 chemical specific CMS Chips and follow the
instructions on the display as to when to move the slide switch. TWA levels
are typically analyzed in 1-2 minutes. Upon completion of this process, the
concentration is indicated on the LCD display. Every Chip uses the exact same
procedure so training is minimal.
The system is based on Drägers 70+ years
of dry chemical reaction technology used in
Dräger-Tubes
®
, however, the Dräger CMS
includes a mass flow controller to take a pre-
cise air sample and the color change is
measured with a photo-optical system elimi-
nating any human subjectivity. Accuracies of
+/- 4 to 10% of measured values are
achieved for most gases and vapors.
Dräger CMS does not require gas calibration.
All measurement and calibration information
is stored on a bar code on the CMS Chip. An
electronic leak check is performed before
each measurement so you are assured of
accurate indications every time. Operating on
4 AA cells, the Dräger CMS will deliver
about 100 measurements per battery
change. An optional remote sampling system
makes the Dräger CMS an ideal choice for
confined space entry applications.
The on-board data-recorder stores up to 50
measurements with the gas/concentration
and date/time. The recorder can be set up to
record manually or automatically, and previ-
ous measurements can be called up on
demand.
The Dräger CMS is currently used extensive-
ly in the petrochemical, transportation, and
utilities industries as well as the fire service
and government regulatory agencies.
Popular applications include TWA screening,
confined space entry and emergency
response.
