Hydrogen Sulfide (H2S) Detector Tubes | Standard Range: 2.5-60ppm | N10-103-10

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: 2.5–60 ppmv
• Extended Range: 1.25–30 ppmv
• Extended Range: 5–120 ppmv
• Number of Pump Strokes (Standard Range): 1
• Sample Volume (Standard Range): 100 mL
• Sample Time (Standard Range): 1.5 minutes
• Correction Factor (Standard Range): 1
• Precision (Relative Standard Deviation): ≤ ±12%
• 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: 0.95 at 0°C/32°F; 0.95 at 10°C/50°F; 1.0 at 25°C/77°F; 1.2 at 40°C/104°F
• Storage Life: 3 years in darkness at 5–25°C (40–77°F); refrigeration preferred
• Color Change: White → Light Brown
• Part Number: N10-103-10

The tube uses a reaction between hydrogen sulfide and lead acetate to produce lead sulfide and a color change from white to light brown. The standard range uses 1 pump stroke with a 100 mL sample volume and a 1.5-minute sampling time.

Cross-Sensitivity: The datasheet reports no apparent response from hydrogen, carbon monoxide, methane, ammonia, sulfur dioxide, carbon disulfide, diethyl sulfide, hexane, isobutylene, or toluene under the listed test conditions. Nitrogen dioxide may interfere in mixtures and may result in a transient light brown H₂S response. High concentrations of sulfur dioxide can suppress the H₂S response. Methyl mercaptan may leave a yellow color over the entire tube at high concentrations.

Important: Hydrogen and isobutylene have no effect in mixtures under the tested conditions.
