Tube - Oil Mist 1/a (10) | Draeger

The Dräger Tube Oil Mist 1/a is a short-term chemical detector tube manufactured by Dräger. It is designed for field measurement of oil aerosol (mist) in air (mineral and synthetic oil aerosols), using a manual pump system. The product is packaged as a box of 10 tubes (10 tests per box).

Key Features & Benefits

• Target measurement: Specifically designed to detect oil aerosols/mist (mineral and synthetic oil aerosols), not oil vapours.

• Measuring range: Standard measurement range is 1 to 10 mg/m³.

• Pump strokes: The typical number of pump strokes (for manual sampling) is about 100 strokes.

• Time for measurement: Approximate measurement time is about 25 minutes under standard conditions.

• Color change indication: The reagent changes from white → brown, providing a visual indication of the concentration reached.

• Simple field usability: These glass tubes are plug-in to a compatible manual pump (for example the Dräger Accuro® pump) and are used for spot checks in the field.

• Applications: Ideal for assessing workplace aerosol exposure (oil mist), leak detection, monitoring in industrial hygiene (machining, metalworking fluids, etc.), and checking in confined spaces.

Technical Specifications

• Measuring range: 1 to 10 mg/m³ (for mineral & synthetic oil aerosols)

• Number of strokes (n): 100 strokes for the manual pump.

• Time for measurement: Approximately 25 minutes.

• Standard deviation: ±30% (as found in one specification listing)

• Ambient/Operating Conditions:

  • Temperature: 10 °C to 30 °C.

  • Absolute humidity: < 20 mg H₂O/L.

• Cross‐sensitivity / Limitations: The tube indicates only mineral and synthetic oil aerosols (mist). Oil vapours and vapours of higher molecular weight organics are not indicated by this tube.

• Tube material: Glass with break-off tips.

• Package quantity: Pack/Box of 10 tubes.

Applications & Use Cases

• Measuring oil aerosol (mist) concentrations in workplaces such as machining centres, metal-working operations, compressor rooms, lubrication systems.

• Spot sampling in areas where oil mist may pose inhalation hazard or contribute to workplace exposure monitoring.

• Pre-entry checks in confined spaces (e.g., machine enclosures, maintenance pits) where oil mist may accumulate.

• Verification of aerosol levels for compliance with occupational hygiene standards or internal safety monitoring programmes.

• Portable field measurement when fixed continuous monitoring instruments are unavailable or not required.

Advantages & Considerations

Advantages:

• Rapid spot sampling capability, enabling quick on-site checks.

• Easy to carry, minimal instrumentation (just pump + tube).

• Visual colour change read-out means less reliance on complex instrumentation.

• Good for audit, verification, initial screening of oil aerosol exposure.

Considerations / Limitations:

• It’s a short‐term detector tube: not designed for continuous monitoring over long periods.

• The measuring range is limited (1-10 mg/m³) — for concentrations outside this range a different tube may be needed.

• Because it only responds to oil aerosols (mist), it will not capture oil vapours or some other organic compounds. Important to choose the correct tube for the target species.

• Accuracy depends strongly on correct pump calibration, correct number of strokes, ambient conditions within specification (temperature/humidity). For example, deviations may affect result reliability.

• Single use: once the tube has reacted, it must be discarded; repeated use is not possible.

• Glass construction means fragile; needs careful handling and storage.

• Colour‐change interpretation involves human estimation of the length of colour path — so some subjectivity unless additional instrumentation/standard used.
