Gastec Hydrogen Sulfide (H₂S) Gas Detector Tubes provide a convenient method for measuring hydrogen sulfide concentrations in air using a compatible Gastec gas sampling pump.

Designed for on-site gas detection, industrial hygiene, workplace air monitoring, occupational safety, process monitoring, and environmental testing, Gastec detector tubes provide a simple visual method for measuring specific gas concentrations without requiring electronic gas detection equipment.

A wide selection of measuring ranges is available to accommodate hydrogen sulfide monitoring applications ranging from low-level PPM concentrations to high percentage-level H₂S measurements.

Common Applications

Gastec Hydrogen Sulfide Gas Detector Tubes can be used with compatible Gastec sampling equipment for workplace air monitoring, industrial hygiene surveys, occupational exposure assessment, wastewater and sewage treatment, petroleum and petrochemical operations, oil and gas facilities, refineries, pulp and paper operations, chemical manufacturing and processing, process monitoring, environmental testing, and workplace safety applications where hydrogen sulfide may be present.

Important

A compatible Gastec Gas Sampling Pump is required to use these detector tubes. Because Gastec offers multiple H₂S detector tubes with significantly different measuring ranges, always select the appropriate part number based on the anticipated hydrogen sulfide concentration and your specific sampling application.

Follow the manufacturer's sampling instructions and correction factors, when applicable, for the specific detector tube being used.
