CMS

CMS: Chip Measurement 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 Times
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. 

Unequalled Accuracy
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.

Chemical Specific Chips
When you need to know exactly what is there, CMS is the tool to provide 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.
