Description
-
Gas to Detect: Hydrogen Sulfide (H₂S)
-
Detection Range:
-
Lower detection limit: 0.2 ppm (parts per million)
-
Upper detection limit: 10 ppm
-
-
Principle of Detection:
-
Colorimetric method (gas reacts with the reagent in the tube to change color)
-
-
Sampling Time:
-
Typically, the detection tubes require 1 to 5 minutes of sampling, depending on airflow and concentration.
-
-
Type of Tube:
-
Short-term measurement (single-use)
-
Typically used with Draeger pumps, such as the Draeger Accuro pump or Draeger Polytron pump.
-
-
Measuring Accuracy:
-
Generally within ±10% for the given concentration.
-
-
Shelf Life:
-
Depending on storage conditions, usually 2 to 3 years.
-
Ensure tubes are stored in a dry, cool place away from direct sunlight.
-
-
Tube Volume:
-
Typically around 5-10 mL of reagent inside the tube.
-
-
Temperature Range:
-
Typically functional in a range of 10°C to 30°C (50°F to 86°F).
-
-
Humidity Range:
-
Most tubes are designed to work within 30% to 90% relative humidity.
-
-
Tube Dimensions:
-
Around 12 cm long with a diameter of about 1 cm.
-
Safety and Handling
-
Always follow the manufacturer's safety instructions when handling and disposing of used tubes.
-
Toxicity of H₂S: Hydrogen Sulfide is highly toxic and can cause serious health effects. Ensure proper ventilation and wear appropriate PPE (personal protective equipment) when using.
Applications
-
Workplace safety in industries like:
-
Petroleum and gas
-
Chemical manufacturing
-
Wastewater treatment
-
Mining
-
-
Environmental monitoring to assess H₂S levels in outdoor air or industrial exhaust.
Advantages
-
Portable and easy to use with Draeger pumps.
-
Immediate results through the color change in the tube, no need for complex equipment.
-
Precise detection for H₂S, helping to ensure compliance with occupational health and safety regulations.
