Hydrogen Sulfide (H2S) Detector Tubes | Standard Range: 0.1-2% | N10-103-40

NAGCO Hydrogen Sulfide (H₂S) 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: 0.1–2%
• Extended Range: 0.05–1%
• Extended Range: 0.2–4%
• Number of Pump Strokes (Standard Range): 1
• Sample Volume (Standard Range): 100 mL
• Sample Time (Standard Range): 2 minutes
• Correction Factor (Standard Range): 1
• Precision (Relative Standard Deviation): ≤ ±10%
• Linearity with Number of Pump Strokes: r² = 0.998
• Humidity: No effect between 5–85% RH
• Temperature Range: 0–40°C (32–104°F)
• Temperature Correction Factor: 1.2 at 0°C/32°F; 1.1 at 18°C/64°F; 1.0 at 25°C/77°F and 40°C/104°F
• Storage Life: 3 years in darkness at 5–25°C (40–77°F); refrigeration preferred
• Color Change: Light Blue → Black
• Part Number: N10-103-40

The tube uses a reaction between hydrogen sulfide and copper sulfate to produce a color change from light blue to black. The standard range uses 1 pump stroke with a 100 mL sample volume and a 2-minute sampling time.

Cross-Sensitivity: The datasheet reports no apparent response from carbon monoxide, methane, nitric oxide, nitrogen dioxide, ammonia, sulfur dioxide, diethyl sulfide, isobutylene, toluene, or hexane under the listed test conditions. Methyl mercaptan may produce an apparent reading and, at high concentrations, can leave a yellow color over the entire tube.

Important: Other possible interferences include high concentrations of ammonia and NO₂ in mixtures. The datasheet reports no response to carbon disulfide (CS₂).
