Standard Measuring Range: 5 to 150 ppm.
Test Volume: 1 L.
Flow Rate: 0.2/min.
Time for Measurement: app. 5 min.
Standard Deviation: ± 10 ... 15 %.
Colour Change: white -> brownish-green.
Ambient Operating Conditions.
Temperature: 0 to 40 °C.
Absolute Humidity: 0 to 50 mg H2O / L.
Pressure: The tube may only be used for depressurized compressed air.
Reaction Principle: 5 CO + I2O5 H2-S2-O7--> I2 + 5 CO2.
Cross Sensitivity Acetylene reacts similar to carbon monoxide, however, with less sensitivity. Petrol, benzene, halogenated hydrocarbons and hydrogen sulphide are retained in the pre-layer.
Higher concentrations of easily cleavable halogenated hydrocarbons(e.g. trichloroethylene), may form chromyl chloride in the prelayer which changes the indicating layer to yellowish-brown.
Carbon monoxide determination is not possible in the case of high olefine concentration.
Extension of the Measuring Range - Using a test volume of 2 L, divide the reading by 2, measuring range 2.5 to 75 ppm.
Product Group Information: EVER SINCE 1937 WHEN WE INTRODUCED OUR FIRST DETECTOR TUBE, DRAEGER HAS BEEN THE WORLD LEADER IN THE ANALYSIS OF GASES AND VAPORS IN THE INDUSTRIAL WORKPLACE. OVER THE YEARS WE HAVE DEVELOPED MORE TUBES AND DETECTION DEVICES FOR MORE APPLICATIONS THAN ANYONE ELSE! OUR LEADING EDGE TECHNOLOGY HAS KEPT US ON THE FOREFRONT OF COLORIMETRIC DETECTOR TUBES THUS PROVIDING THE MOST ACCURATE AND SPECIFIC RESULTS AVAILABLE.
Simple to use.
Calibration not required.
Inexpensive and portable.
Wide variety of gases and vapors.
70 years of proven technology.
Most Trusted - Draeger-Tubes® have been leading the way in gas detection for over 60 years.
Widest Range - Over 200 different Draeger-Tubes® are available for measuring over 500 gases and vapors.
Hassle-Free Operation - No calibration, no lubrication, no special maintenance. Always ready to go.
Accurate Not all detector tubes are created equal! Draeger-Tubes® with the accuro pump deliver the most accurate results. Many Draeger tubes offer a +/- 10% standard deviation on the results. This is a result of our 60+ years of manufacturing colorimetric tubes and the consistent volume delivered by the bellows pump design. Quality assurance is accomplished by individually calibrating each batch of Draeger-Tubes®. Then every batch is tested at regular intervals, throughout the two year shelf life, to guarantee accuracy over the entire life of the tubes.
Easy to Read See the difference for yourself! The wider diameter of the Draeger-Tubes® makes it easier to read. Well-spaced graduation marks enable distinct and decisive measurement results. Color changes to the reagents are well defined over the entire length of the stain. Many Tubes offer a dual calibrated scale so that you can interpret the results without using multiplication factors.
Fast One stroke tubes are not always faster! Though many Draeger-Tubes® require more than one stroke, they often provide measurement results in less time. Not only do you get the benefit of a quicker analysis; the larger sample volume provides better statistical accuracy.
Flexible Draeger-Tubes® simply deliver more! More gases and more measuring ranges than any other manufacturer. Draeger offers over 200 tubes for accurately measuring over 500 different gases. You can measure ambient air for health and safety levels and optional equipment allows you to measure stack gases, motor vehicle exhaust components, pressurized gas line samples and contaminants in compressed air and other technical gases. Other specialized tubes measure over a period of hours or a complete work shift to indicate daily exposure levels.
Specific Reagents used in Draeger-Tubes® are chosen to provide not only the most accurate, but also most specific results possible. Our use of pre-layers on many tubes (like benzene) remove other potential interfering gases (e.g. aromatic hydrocarbons) so you measure only the targeted chemical, getting only the results you want. This design enables you to measure specific gases in a complex ambient background found in the measurement area.
