Dräger Gas Detection Tubes (D-G) provide a simple, reliable method for measuring specific gases, toxic chemicals, and vapors in workplace and industrial environments. These colorimetric detector tubes use a chemical reagent that changes color when the target substance is present, allowing users to identify and measure gas concentrations directly at the sampling location.

Dräger short-term detector tubes are available in numerous configurations, with different measurement ranges for specific gases and chemical compounds. The A–B product selection allows customers to choose from available Dräger tube models according to the substance they need to detect

Designed for use with the Dräger accuro manual sampling pump, these gas detection tubes are commonly used for industrial hygiene assessments, workplace air monitoring, leak investigations, confined-space evaluations, and chemical exposure screening.

Key Features of Dräger Gas Detection Tubes

• Chemical-Specific Detection: Individual tube models are designed to detect particular gases, vapors, or chemical compounds.

• Colorimetric Measurement: A visible color change indicates the presence and concentration of the target substance.

• Direct Measurement Results: Graduated measurement scales on many tubes allow users to read results directly from the tube.

• Easy Operation: Designed for use with the Dräger accuro manual bellows sampling pump.

• Multiple Measurement Ranges: Select from different tube models and concentration ranges to match your application.

• Fast Testing: Depending on the tube model and required pump strokes, measurements can take seconds to minutes.

• Portable Testing: Compact tubes and a manual sampling pump make the system convenient for field measurements.

• Quality-Controlled Manufacturing: Dräger calibrates and tests tube production batches to support consistent measurement performance. 

How Do Dräger Gas Detector Tubes Work?

Dräger detector tubes are sealed glass tubes containing chemical reagents that react with a specific gas or family of chemical compounds.

To perform a measurement, the sealed ends of the tube are opened using an appropriate tube opener. The tube is then connected to a compatible Dräger accuro sampling pump. The pump draws a measured volume of air through the tube.

If the target gas is present, the chemical reagent changes color. The length of the resulting color stain is compared with the graduated scale printed on the tube to determine the approximate gas concentration.

Each Dräger tube has its own measurement range, sampling requirements, number of pump strokes, and operating instructions. Always follow the instructions supplied with the specific tube being used.

Industrial and Workplace Applications

Dräger short-term gas detection tubes are used in a variety of applications where workers need to identify or measure potentially hazardous gases and vapors.

Common applications include:

• Industrial hygiene and workplace exposure assessments

• Chemical manufacturing and processing

• Industrial maintenance and troubleshooting

• Confined-space atmospheric evaluations

• Chemical storage and handling facilities

• Leak detection and investigation

• Environmental air monitoring

• Manufacturing and production facilities

• Occupational health and safety inspections

Dräger also offers specialized detector tubes and accessories for applications involving compressed gases, technical gases, and other sampling requirements.

Why Choose Dräger Detector Tubes?

Dräger has developed gas detection tubes for decades, offering a broad selection of chemical-specific measurement solutions. Its short-term detector tube portfolio includes more than 200 tube types for measuring over 500 gases and vapors.

The colorimetric measurement method provides a convenient way to perform on-site gas testing without requiring a conventional electronic gas monitor. Different tube configurations offer different measurement ranges, sensitivities, and sampling procedures to support a wide range of industrial testing requirements.

Required Equipment and Accessories

Dräger short-term detector tubes require a compatible sampling pump to draw the air sample through the tube.

The Dräger accuro manual sampling pump is designed specifically for use with Dräger detector tubes and draws a nominal 100 mL air sample per complete pump stroke.

Additional accessories may include:

• Dräger accuro sampling pump

• Dräger tube opener

• Appropriate tubing and sampling accessories when required by the application

• Carrying cases and storage accessories

Important: Detector tubes are sold separately from the sampling pump unless specifically identified as part of a kit.

Product Selection and Ordering Information

When selecting a Dräger gas detection tube, it is important to identify the chemical you need to measure and choose a tube with the appropriate measurement range.

Frequently Asked Questions About Dräger Gas Detection Tubes

1. What are Dräger gas detection tubes used for?

Dräger gas detection tubes are used to detect and measure specific gases, toxic chemicals, and vapors in air. They are commonly used for workplace air monitoring, industrial hygiene testing, leak investigations, confined-space evaluations, and chemical exposure assessments.

2. How do Dräger detector tubes work?

Dräger detector tubes contain chemical reagents that change color when exposed to the target gas. Air is drawn through the tube using a compatible sampling pump. The length of the color change is compared with the graduated scale to determine the approximate gas concentration.

3. Do Dräger gas detection tubes require a sampling pump?

Yes. Dräger short-term detector tubes require a compatible sampling pump, such as the Dräger accuro manual bellows pump, to draw an air sample through the tube. The pump is generally purchased separately.

4. What is the Dräger accuro pump?

The Dräger accuro is a manual bellows sampling pump designed for use with Dräger detector tubes. It draws a nominal 100 mL air sample through the tube with each complete pump stroke.

5. How many gases can Dräger detector tubes measure?

Dräger offers more than 200 different short-term detector tube types for measuring over 500 gases and vapors. Each tube is designed for a particular chemical or group of substances.

6. What is the difference between Dräger short-term detector tubes?

Individual Dräger tubes differ in the chemical they detect, measurement range, sensitivity, required pump strokes, and sampling time. It is important to select the tube that matches the specific gas and concentration range you need to measure.

7. How long does it take to get a reading from a Dräger gas detection tube?

Measurement time depends on the specific tube and the number of required pump strokes. Dräger short-term detector tubes can provide results in approximately 5 seconds to 15 minutes, depending on the application and tube model.

8. How many Dräger tubes come in a box?

Most Dräger short-term detector tubes are packaged in boxes of 10. Packaging quantities can vary by tube model, so customers should verify the quantity listed for the specific product selected.

9. What is the shelf life of Dräger gas detection tubes?

Many Dräger short-term detector tubes have a shelf life of approximately two years. However, expiration dates vary by tube model. Always check the expiration date printed on the packaging before use.

10. Can Dräger tubes measure more than one gas at a time?

Most standard Dräger short-term detector tubes are designed to detect a specific gas or chemical group. Specialized Dräger simultaneous test sets are also available for measuring multiple selected gases using several tubes together.

11. Can Dräger detector tubes be used for confined-space testing?

Yes. Appropriate Dräger detector tubes can be used for spot measurements during confined-space atmospheric evaluations. The correct tube must be selected for the specific gases of concern. Detector tubes should not replace required atmospheric monitoring equipment or established confined-space safety procedures.

12. How do I choose the correct Dräger gas detection tube?

Start by identifying the gas or chemical you need to detect. Then select a Dräger tube with the appropriate measurement range and sensitivity for your application. Verify the tube's part number, pump requirements, and operating instructions before ordering.
