Draeger, Inc. - DRA 6733171 - DT Aniline 0.5/a (10)
Items #:
DRA 6733171
Dräger-Tubes - Aniline 0.5/a, Short-term Tubes, 10 tests per box, By Dräger, P/N 6733171
Dräger-Tubes - Aniline 0.5/a, Short-term Tubes, 10 tests per box, By Dräger, P/N 6733171
Application Range
Standard Measuring Range: 0.5 to 10 ppm
Number of Strokes n: 20
Time for Measurement: app. 4 min
Standard Deviation: ± 15 to 20 %
Colour Change: pale yellow -> pale green
Ambient Operating Conditions - Temperature: 15 to 30 °C,Absolute Humidity: 7 to 12 mg H2O / L
Reaction Principle - C6H5NH2 + CrVI -> CrIII + various oxidation products
Cross Sensivity - When methyl aniline and aniline are present at the same time, it isimpossible to measure only the aniline concentration.Ethers, ketones, esters, aromatics and petrols are indicated as well butwith different sensitivities.High aniline concentrations will not be indicated.
Draeger, Inc. - DRA 8101161 - DT Butadiene 10/a-D (10)
Items #:
DRA 8101161
Dräger Diffusion Tube, Carbon Monoxide 50/a-D, 10 to 300 ppm, 1.3 to 40 ppm, Draeger 8101161
Draeger Diffusion Tube, Ammonia 20/a-D, Standard Range of Measurement (20 degrees C, 1013 hPa) 10 to 300 ppm, Standard Range of Measurement for Maximum Period of Use (20 degrees C, 1013 hPa) 1.3 to 40 ppm, Dräger 8101161
Dräger Diffusion Tubes with Direct Indication
Direct-reading Dräger diffusion tubes were developed especially for personal exposure monitoring.
Benefits
These systems do not require the use of a gas detector pump because the contaminant molecules pass into the tube by diffusion processes and in this manner are brought into contact with the reagent systems.
Draeger, Inc. - DRA 8101341 - DR Tetrahydrothiophene 1/b (5)
Items #:
DRA 8101341
Product Specific Information; Dräger Tubes - Tetrahydrothiophene 1/b, Short Term Tubes, 5 tests per box, Draeger P/N 8101341
Standard Measuring Range : 1 to 10 ppm
Number of Strokes (n) : 30
Time for Measurement :
app. 15 min
app. 10 min for ameasurement in natural gas.
Standard Deviation : ± 15 to 20 %
Colour Change : violet -> yellow brown
Ambient Operating Conditions
Temperature : 0 to 35 °C
Absolute Humidity : < 30 mg H2O / L
Reaction Principle
a) Adsorption with H2S
b) THT + KMnO4 -> yellow brown reaction product
Cross Sensitivity
Up to 10 ppm hydrogen sulphide is adsorbed in the pretube,causing a brown discoloration.
It is impossible to measure tetrahydrothiophene in the presence ofmercaptans.
Up to 100 ppm of olefines (e.g. ethene, propene) will cause thecolour of the indicating layer to become lighter, at higher concentrationsthe olefins cause plus errors.
Up to 200 ppm methanol does not interfere.
