Honeywell H2S Gas Detection Tubes (10-120 ppm) | Hydrogen Sulfide Tester

Hydrogen Sulfide (H2S) is a highly toxic, invisible gas frequently encountered during sour gas drilling, flowback operations, and crude oil tank gauging. While electronic personal monitors are essential for continuous exposure tracking, safety managers and industrial hygienists often require an immediate, precise spot-check of atmospheric conditions before clearing a confined space for entry. These Honeywell Colorimetric Gas Detection Tubes provide a fast, highly accurate, and reliable method for measuring H2S concentrations without the need for electronic sensors or field calibration.

Specifically engineered under Part Number H-10-103-15, these tubes are designed to detect Hydrogen Sulfide within a critical mid-level range of 10 to 120 ppmv (parts per million by volume). The testing process is incredibly efficient, requiring only a single pump stroke to draw a precise 100 mL air sample through the chemical bed. As the sample passes through, the reagent instantly reacts with the H2S gas, changing color to provide a direct-read measurement against the clear, printed scale on the glass tube.

Because they operate entirely on a mechanical hand pump system, these single-use tubes require no batteries, sensor warm-ups, or bump testing, making them an invaluable fail-safe for rig safety. Hermetically sealed in heavy-duty glass to prevent contamination, they are easily stored in a safety manager’s truck or rig doghouse, ensuring that accurate gas detection is always available when verifying atmospheric safety in trenches, bulk storage tanks, or around sour iron.

Features & Benefits

• Targeted Detection Range: Accurately measures H2S concentrations from 10 to 120 ppmv, ideal for critical mid-level exposure verification.

• Fast & Efficient Sampling: Requires only a single pump stroke (100 mL sample volume), allowing for rapid field deployment and fast results.

• Instant Visual Reading: Chemical reagent changes color instantly upon contact with H2S, providing an unmistakable, direct-read measurement.

• Zero Calibration Required: Unlike electronic gas monitors, these single-use tubes require no bump testing, sensor calibration, or battery maintenance prior to use.

• Compound-Specific Accuracy: Engineered to minimize cross-sensitivity with other common oilfield gases, ensuring a reliable reading of Hydrogen Sulfide.

Specifications & Technical Details

Applications

The Honeywell H-10-103-15 H2S Tubes are a staple for industrial hygienists, HSE managers, and confined space rescue teams across the oil and gas industry. They are heavily utilized for spot-checking atmospheric conditions inside bulk crude storage tanks, verifying gas levels during sour well interventions, and ensuring trenches and low-lying areas are safe for personnel prior to hot work.

Quality Assurance

Manufactured under strict laboratory conditions by Honeywell to ensure absolute consistency in the chemical reagent mix. Each batch is rigorously tested against known calibration gases to guarantee the printed scale delivers highly accurate, repeatable readings in the field. The tubes are hermetically sealed in heavy-duty glass to prevent contamination and degradation prior to use. (Note: Hand pump sold separately).
