Draeger 3740290 Alcohol 10/A Detector Tube (10 Tests Per Box)

Application Range

• Standard Measuring Range: 10 - 500 ppm
• Number of Strokes n: 5
• Time for Measurement: 7.5 min.
• Standard Deviation: ± 10 - 25 %
• Color Change: Yellow → Mint Green

Ambient Operating Conditions

• Temperature: 0 to 40 °C
• Absolute Humidity: 1 – 20 mg/L

Reaction Principle

• Alcohol + organometallic compounds → green reaction product

Cross Sensitivity

• Methanol, ethanol, iso-propanol, and n-butanol are indicated with the same sensitivity.
• N-propanol, 2-butanol, i-butanol, and tert-butanol are indicated with half sensitivity (indication × 2 = measured value).

Permissible Ambient Conditions

• Temperature: 0 to 40°C / 32 to 104°F
• Temperature Correction:
  • 15 - 25°C / 59 - 77°F → none                                               
  • <15°C / 59°F  → +10 % of the measured value per °C
  • >15°C / 59°F  → -4.5 % of the measured value per °C
• Absolute Humidity: 1 – 20 mg/L

Reaction Principle

• Alcohol + organometallic compounds → green reaction product

Cross Sensitivity

• Methanol, ethanol, iso-propanol, and n-butanol are indicated with the same sensitivity.
• N-propanol, 2-butanol, i-butanol, and tert-butanol are indicated with half sensitivity (indication × 2 = measured value).

• The following substances are not indicated in the given concentration range:

  • ≤ 2000 ppm acetone

  • ≤ 10 ppm formaldehyde

  • ≤ 50 ppm acetaldehyde
