Tube Hydrogen 0.2%/a (10) | Draeger

Gas Measured:

• Hydrogen (H₂)

Concentration Range:

• 0.2% (2,000 ppm) to 10% (100,000 ppm)

  • The tube can measure hydrogen concentrations in this range.

  • The "0.2%/a" refers to the sensitivity and the way the color changes relative to hydrogen concentration.

Detection Principle:

• Colorimetric Method:

  • The tube contains a chemical reagent that reacts with hydrogen. The reaction causes the tube to change color, and the extent of the color change is proportional to the concentration of hydrogen gas present.

Tube Length:

• Approx. 10-15 cm (depending on the specific tube model)

Time to Read:

• Typically, Draeger gas detection tubes provide results in 1-5 minutes, depending on the concentration of the gas being detected.

Detection Sensitivity:

• The tube is calibrated to detect hydrogen concentrations at 0.2% per year with a sensitivity of 0.2%/a.

• This means the tube will respond to changes in hydrogen concentration at that rate.

Number of Tubes:

• Pack of 10 tubes

  • This product is sold in a pack of 10, providing enough tubes for multiple tests.

Pump Required:

• Draeger Accuro Pump or other Draeger gas detection pumps.

  • A pump is needed to draw a specific volume of air through the tube for accurate measurement.

Application:

• Industrial and Laboratory Use: The hydrogen detection tube is ideal for environments where hydrogen gas might be present, such as chemical factories, laboratories, refineries, or any industrial process that uses or generates hydrogen gas.

• Safety Monitoring: Hydrogen is highly flammable and can be hazardous at elevated concentrations. The tube helps monitor for safe levels in the workplace.

Packaging:

• Quantity: 10 tubes per box.

Storage & Shelf Life:

• Storage: Store the tubes in a cool, dry place, away from direct sunlight and extreme temperatures.

• Shelf Life: Typically 1-2 years, depending on the storage conditions. The expiration date is usually printed on the packaging.

Calibration:

• Draeger gas detection tubes often require periodic calibration to ensure accurate readings. Calibration details and the interval should be referred to in the user manual for the specific tube.

Instructions for Use:

1. Insert the tube into a Draeger pump.

2. Draw the air through the tube using the pump (specific volume will be indicated in the tube's instructions).

3. Wait for the reaction to occur, which causes the tube to change color.

4. Compare the color change against the provided scale to determine the hydrogen concentration in the air.

Safety Information:

• Hydrogen is a highly flammable gas, and safety precautions must be observed when handling the tube and in environments where hydrogen is present.

• Always follow proper ventilation guidelines when measuring gases like hydrogen in confined spaces.
