Gastec Hydrogen Sulphide (H_2S) Detector Tube – No. 4HH

High-Concentration Analysis for Industrial Process Monitoring

The Gastec No. 4HH detector tube is engineered for the detection of high concentrations of Hydrogen Sulphide (H_2S). Unlike standard safety tubes that measure in parts per million (ppm), the 4HH measures in percentages (%), making it the ideal choice for monitoring process gases, high-pressure lines, and sour gas concentrations in industrial applications where H_2S levels are extremely high.

Key Features

• High-Range Detection: Capable of measuring $H_2S$ levels from 0.1% up to 4.0%, providing essential data for process control and high-hazard environments.

• Instant Results: The colorimetric glass tube provides a direct, easy-to-read scale, eliminating the need for expensive electronic sensors in high-corrosion areas.

• Japanese Engineering: Manufactured to the highest quality standards by Gastec, ensuring reliability and accuracy in every test (QC No. 50463).

• Remote Sampling Ready: Compatible with extension hoses up to 30 meters, allowing for safe sampling of high-concentration areas from a distance.
