The world's only Chip Measurement System (CMS) makes spot measurements as easy
as 1, 2, 3: insert chip – start measurement – read measurement result on the LCD
display. The Drager CMS combines the advantages of the Drager-Tubes with those
of an optoelectronic analysis system. Two components define the system: the analyser
and the substance-specific chip.
Simple to use
The Drager CMS is ready for use after
only a brief instruction. It makes no
difference which gas or vapour you wish
to measure – the instrument is used in
the same way every time. The operation
is guided by a menu on the display and a
single button/switch. The display can be
backlit and is available in German, English,
French or Spanish.
After an automatic
system self-test, the analyser is powered
up and the measurement system is
immediately ready for operation. Simply
insert the chip, perform the measurement
and read the measurement result displayed
as a concentration on the screen.
end of the measurement, the chip is
automatically ejected from the instrument,
and the analyser shuts down. An audible
signal sounds after each operating step.
Power is supplied by four standard and
easily replaceable batteries which are especially suited to the analyser's
requirements (see technical data).
The battery capacity allows for more than
seven hours of measurement and is, of
course, always displayed on the screen.
The principle of mass current measurement
ensures that the instrument remains
unaffected by fluctuations in air pressure.
Because the chips are calibrated before
leaving the factory, there is no need for
the user to calibrate the Drager CMS.
Any possible temperature and humidity
effects are checked during factory
calibration. The analyser is explosion
protected and certified in accordance with
Cenelec (Europe), UL (USA) and UL/CSA
In addition, the system is
protected against dust and splash water in
accordance with IP 54, and is resistant to
To allow measurements at places which
are difficult to access, a remote system is
available. This comprises of an additional
pump and extension hose, and is
connected to the back of the analyser.
Because the remote system is activated
by its own switch, the system can remain
attached to the analyser. A telescopic
probe can also be attached to the
