Hydrogen Sulfide (H2S) NG Detector Tubes | Standard Range: 1-7ppm | N10-103-07

NAGCO Hydrogen Sulfide (H₂S) NG detector tubes are designed for measuring hydrogen sulfide concentrations using NAGCO pumps and tubes. The tubes provide three measurement ranges for flexibility across different H₂S concentrations.

Specifications:

• Standard Range: 1–7 ppm
• Extended Range: 0.5–3.5 ppm
• Extended Range: 0.25–1.75 ppm
• Number of Pump Strokes (Standard Range): 0.5
• Sample Volume (Standard Range): 50 mL
• Sample Time (Standard Range): 40 seconds
• Correction Factor (Standard Range): 1
• Precision (Relative Standard Deviation): ≤12%
• Humidity: Tubes must be used at <5% RH; reading drops sharply above 5% RH
• Temperature Range: No effect between 0–40°C (32–104°F)
• Storage Life: 1 year in darkness at 5–10°C (40–50°F); refrigeration preferred
• Color Change: Pale orange → Pink
• Part Number: N10-103-07

The tube's measurement range can be adjusted by changing the number of pump strokes. The standard range uses 0.5 pump strokes with a 50 mL sample volume and 40-second sample time.

Cross-Sensitivity: The tube has documented cross-sensitivity to methyl mercaptan and butyl mercaptan. Other tested substances—including NH₃, NO₂, SO₂, CS₂, CO, hexane, isobutylene, and toluene—show little to no apparent reading under the listed test conditions. HCl and other acids and bases may also interfere with measurements.
