Chip Measurement System
from Draeger Safety

The System

The CMS combines substance specific measuring Chips with an electronic based Analyzer for an easy to use spot-measurement system. The 10 capillaries in each Chip are filled with a reagent system based on Draeger's 60+ years of colorimetric chemistry expertise. The analyzer combines a revolutionary optical system for analyzing the color reaction with a mass flow controller and pump system that provides unbeatable reproducibility.

Fast Response Time

The CMS Analyzer requires no warm-up time. After taking a test, the results can be reported as quickly as 20 seconds. Higher concentrations, which pose a greater hazard, are reported faster than trace background levels. This increases the safety of using the CMS system.TWA and action levels are typically analyzed within 1-2 minutes. After providing the measurement results, the CMS is immediately ready for another test or another Chip for further analysis of the environment.

The expertise of Draeger's worldwide experience in industrial gas measurement has come to focus in the CMS. This is combined with a photo-optical controller that measures the speed of the chemical reaction, thus eliminating the human objectivity. Unlike other systems that rely on the volume of air, the CMS pulls the same mass of air through the capillary every time. The mass flow controller automatically compensates for changes in atmospheric pressure.

Accuracies of ±4 to 7% measured value is achieved for most gases. CMS has been validated by a nationally accredited third party laboratory

Chemical Specific Chips

When you need to know exactly what is there, CMS is the tool to provide you those answers. The chemistry is chosen to provide the best results possible. The capillaries of several chips have multiple levels (Yes, even in something that small!) to help eliminate cross sensitivity or derive a specific measurement of the targeted chemical.

The CMS Chip

The Chip consists of 10 measurement capillaries filled with substance-specific reagent systems. The gas type, part number and batch number are printed on the chip. A printed barcode on the chip, read by the analyzer optics, contains information about gas type, measuring range and measuring time required for completing the measurement. Each chip is calibrated during manufacturing and is valid for two years.

Simplified Operation The CMS is literally as easy to operate as 1-2-3. Making analysis is as simple as turning the unit "on" (moving the slide position to position 1), then following the plain language instructions on the display to load the Chip and move the slide selector to positions 2 and 3. Operating the CMS could not be easier because this is the exact same procedure for every Chip! Upon completion of analysis, the CMS Analyzer shows the concentration in the display. Any misinterpretation of the results is eliminated by the unambiguous digital display of the concentration.

Simplified Maintenance

Data Recorder

The internal data recorder stores up to fifty measurements with the time/date, contaminant/concentration and the sequential number of the measurement in a series. Measurement location information (in alphabetical code) may be entered manually. The stored data can be recalled and displayed on demand.

Accessories In order to measure inaccessible areas, the analyzer can be equipped with a remote system which consists of an additional pump and extension hose. The remote system can be installed in the back of the analyzer. Once attached, the remote system is activated by a separate switch and can remain mounted to the analyzer indefinitely. Additionally, a telescopic wand may be used for remote sampling. A kit for emergency response is now available. It includes an analyzer, remote system, telescopic probe, 10 chips, flashlight/lantern, notepad and a chip case. Note: Chips marked with a (*) are included with this kit.
