• Dräger gas detection tubes measure gas concentrations in the air using glass tubes filled with a chemical reagent that changes colour when it reacts with the target gas. 
• The concentration is read on a calibrated scale in units like ppm or Vol.-%.
• A pump, such as the Dräger accuro, pulls air through the tube to determine the gas concentration.
• Before measuring, perform a leak test on the pump, and follow the instructions for the number of pump strokes needed.

• Workplace Monitoring: Measuring air contaminants according to workplace exposure limits to protect employee health.
• Clearance Measurements: Ensuring that areas are free of hazardous gases before entry or re-entry, particularly in confined spaces.
• Leak Detection: Identifying and locating dangerous gas leaks to prevent exposure and ensure safety.
• Quality Control: Checking compressed breathing air for contaminants such as CO, CO₂, water, and oil content with the Dräger Aerotest.
• Hazard assessment: Identification of unknown gases, aerosols, or vapours.
• Short-Term Measurements: Capturing momentary concentrations in various applications such as wineries, tunnel rescue operations, or recycling facilities.

Cost-Effective:

• Generally lower cost compared to electronic gas detectors.
• No need for expensive calibration equipment.

Simplicity:

• Easy to use with minimal training required.
• No complex setup or programming necessary.

Portability:

• Lightweight and compact, making them easy to carry and use in the field.
• Ideal for on-site, spot-check measurements.

Immediate Results:

• Provide instant readings without the need for laboratory analysis.
• Quick decision-making in emergency situations.

High Sensitivity:

• Capable of detecting gases at very low concentrations (ppb levels).
• Suitable for environments with strict safety requirements

... and further advantages especially for Dräger-Tubes

• Information on the number of strokes on each tube
• Extensive information on measurement strategies and cross-sensitivities 
• Own test laboratory
• Documentation support with Dräger Tubes App
• Calibration certificates for download

In uncertain hazardous situations, our simultaneous test sets are helpful. They consist of five parallel Dräger-Tubes that simultaneously indicate different substances, allowing for quick risk assessment.

Dräger-Tubes typically have a shelf life of up to two years. Adhering to the expiration date is crucial for accurate results. Dräger retains samples from each production batch and conducts regular control measurements to ensure the quality within their lifetime.

Use Dräger VOICE, our hazardous substances database with information on over 1,600 hazardous substances. It provides recommendations for measurement and protection against these substances, as well as guidance on using the recommended products. The recommended Dräger-Tubes for detecting the selected substance are grouped into short-term and long-term tubes, as well as the MicroTubes system. Product information includes images, order numbers, measurement ranges, and cross-sensitivities.

The documentation can be done with the Dräger-Tubes app. With the app, you can scan, record, and analyse measurement results, making the documentation process easier and faster. The app is available for free for iOS and Android.
