The Draeger CMS is ready for use after only a brief instruction. It makes no difference which gas or vapor 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 analyzer is powered up and the measurement system is immediately ready for operation.
Simply insert the chip (each chip can conduct 10 tests), perform the measurement and read the measurement result displayed as a concentration on the screen. At the end of the measurement, the chip is automatically ejected from the instrument, and the analyzer shuts down. An audible signal sounds after each operating step. 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 previous measurements can be called up on demand.
Power is supplied by four standard and easily replaceable batteries which 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 Dräger CMS is currently used extensively 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.
Accurate 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 Dräger CMS. Any possible temperature and humidity effects are checked during factory calibration. The analyzer is explosionprotected 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.
