27 | DRÄGER GAS DETECTION
Accurate gas measurements are made easier with the Dräger-CMS
®
. This 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 Dräger’s 70+
years of dry chemical reaction technology
used in Dräger-Tubes
®
, however, the
Dräger CMS includes a mass flow
controller to take a precise air sample
and the color change is measured with a
photo-optical system eliminating any
human subjectivity. Accuracies of +/- 4 to
10% of measured values are achieved for
most gases and vapors.
Dräger CMS does not require gas cali-
bration. 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 indica-
tions 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/concen-
tration and date/time. The recorder can
be set up to record manually or automat-
ically, and previous measurements can be
called up on demand.
The Dräger CMS is currently used exten-
sively in the petrochemical, transporta-
tion, and utilities industries as well as the
fire service and government regulatory
agencies. Popular applications include
TWA screening, confined space entry
and emergency response.
