Chip Measurement System [CMS]

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.

 

Features:

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.

 

Accuracy

Accuracies of +/- 4 to 7% of measured value is achieved for most gases.

 

Chemical Specific Chips

The capillaries of several chips have multiple levels 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.

 

Data Recorder

The internal datarecorder 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.
