Draeger 8103861 n-Butanol 10/a Detector Tubes (10 tests per box)

Application Range:

• Standard Measuring Range: 10 to 250 ppm
• Number of Strokes n: 20
• Time for Measurement: Approx. 6 mins
• Standard Deviation: ± 10 to 25 %
• Color Change: Yellow → Mint Green

Ambient Operating Conditions:

• Temperature: 15 to 30 °C
• Absolute Humidity: 3 to 15 mg H2O / L

Reaction Principle:

• n-butanol + organometallic compound → green reaction product

Cross Sensitivity:

• The tube does not differentiate between different alcohols. 2-butanol is indicated with the same sensitivity. During the measurement of isobutanol with n = 2/10 strokes, the concentration read must be multiplied by a factor of 0.4. During the measurement of tert-butanol with n = 2/10 strokes, the concentration read must be multiplied by a factor of 3.0.
• Methanol is indicated with 2 times (n=10) to 3 times (n=2) its sensitivity, ethanol and isopropanol are indicated with 1 time (n=10) to 2 times (n=2) their sensitivity. Higher molecular alcohols are indicated with significantly decreasing sensitivity. Ethers are indicated with a different sensitivity. ≤ 25 ppm formaldehyde, ≤ 50 ppm acetaldehyde, and ≤ 50 ppm toluene are not indicated.
• Aliphatic petroleum hydrocarbons, ketones, esters, halogenated hydrocarbons and benzene are not indicated.
