 Chip detection system
Chip inspection systems are by far the most accurate and reliable portable test instruments for measuring gas and vapor concentrations.
It consists of an electronic analyzer with a specific physical chip. Ten on each chip are filled with reagent-reagent capillaries. This system was developed on the basis of Dräger's 60 years of experience in this area. With more than 55 gas specific chips, the results of 50 measurements and related data (test substance, concentration, date, measurement time and location) can be stored in a data logger integrated in the analyzer
The CMS host analyzer recorded the results with an electronic eye, which eliminated the artifact factor. The air flow sensor is integrated into the air pump system to measure the air flow, which ensures that the gas entering the chip will maintain a constant air flow independent of fluctuations in the atmospheric pressure. The constant air flow combined with the sensitive reagent system on the chip guarantees Accurate measurement results.
In order to work in harsh gases and vapors in the workplace environment, CMS host has the following advantages:
Easy to use (1 - insert chip, 2 - slide switch, 3 - read shows the result of all gases and vapors)
No calibration required
Digital display of measurement results
 
easy to use
Using Dräger CMS reduces training costs, primarily because the Dräger CMS measures the same measurement regardless of the gas or steam being measured. Intuitive menu command display and one-touch operation further simplify the measurement procedure.
After the analyzer is started, the self-test program is executed automatically. After the self-test is completed, the chip is inserted into the analyzer to start the measurement. The measurement result will be displayed in the form of gas concentration.
After measuring, the chip pops up automatically, the analyzer automatically shuts off, the instrument will signal the end of each operation. The instrument is easy to replace the four standard battery-powered, need to select the battery meets the technical requirements (see the technical parameters of the table), the battery capacity determines the analyzer measurement time, the longest working hours up to seven hours, the display will show the remaining battery capacity.
The principle of controlling the air flow eliminates the fluctuations caused by atmospheric pressure changes. The chip has been calibrated at the factory so there is no need to calibrate in the field. The factory calibration has taken into account the influence of temperature and humidity.
 
Long-distance measurement
In order to measure inaccessible area, the analyzer can be equipped with a long-distance detection system, including a pump and extension tube. The remote detection system is installed on the back of the mainframe and is automatically activated. The mainframe measures and, in addition, With a remote sampling gun.
The analyzer has a built-in data memory and a clock. In order to keep the Dräger CMS in a simple operation, the measurement results are stored in the built-in memory and also guided by a menu. Up to 50 measurements can be stored, including the name of the gas under test , Concentration, test date and time, and measurement site code. The analyzer does not require any maintenance, but it is recommended to test it once a year.
 
CMS chip
Each chip contains a special chemical reagent in the measuring channel consisting of ten capillaries containing a special reagent reagent system. The lower reagent content ensures fast and reproducible reaction with the gas. Each chip has been calibrated at the factory , The use of up to two years.
Benzene, toluene, xylene, carbon monoxide, hydrogen sulfide, sulfur dioxide, ammonia, phosgene, nitrogen dioxide, hydrochloric acid, formaldehyde, hydrocyanic acid and other 50 kinds of gases
