GASTEC Detector Tube Hydrogen Sulphide High Range (10 Pack)

Code: 4H

Contains Mercury: No

Marked Hazardous: No

The Gastec 4H tube provides reliable and precise measurement of hydrogen sulfide concentrations over a wide range from 10 to 4000 ppm using a simple colorimetric detection method with no need for calibration.


 Product Highlights:



  • Measuring Range: 10 to 4000 ppm (with scale typically from 100 to 2000 ppm)

  • Detecting Limit: Approximately 2 ppm using 10 pump strokes

  • Shelf Life: Typically, 3 years when stored in a cool, dark place

  • Number of Pump Strokes: Variable depending on concentration range; usually 1 to 10 strokes

  • Reaction Principle: The tube reagent reacts with hydrogen sulfide to form lead sulfide (PbS), causing a color change from white to brown along the tube length, directly proportional to gas concentration

  • Relative Standard Deviation: Approximately 5% in the mid-range (100–2000 ppm), indicating good precision
