This is the Ammonia 0.2-5 ppm chip.

Simple to use

The Draeger Chips CMS is ready for use after only a brief instruction. It makes no difference which gas or vapor you wish to measure – you can use the instrument in the same way every time. You guide the operation 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 analyzer powers 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. At the end of the measurement, the chip automatically ejects from the instrument, and the analyzer shuts down. An audible signal sounds after each operating step. Four standard and easily replaceable batteries supply power. The batteries are especially suited to the analyzer’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. Draeger calibrates the chips before they leave the factory, so there is no need for the user to calibrate the Dräger CMS. Draeger also checks for any possible temperature and humidity effects during factory calibration. The analyzer is explosion protected and certified in accordance with Cenelec (Europe), UL (USA) and UL/CSA (Canada). In addition, the system is protected against dust and splash water in accordance with IP 54, and is resistant to electromagnetic waves.


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. You can also attach a telescopic probe to the Remote-System.
