Gastec Water Vapour (H_2O) Detector Tube – No. 6L

Precision Moisture Analysis for Compressed Air and Gas Systems

The Gastec No. 6L detector tube is a reliable solution for measuring the concentration of water vapour in air or technical gases. It is specifically designed to detect low levels of moisture, which is critical for preventing corrosion in pipelines, protecting sensitive pneumatic equipment, and ensuring the quality of industrial gas streams.

Key Features

• Accurate Moisture Measurement: Provides a clear visual reading of water vapour content in milligrams per liter (mg/L).

• High Sensitivity: Capable of detecting concentrations as low as 0.05 mg/L, making it ideal for verifying the efficiency of air dryers and desiccant systems.

• Instant Results: The colorimetric change from Green to Yellow provides an immediate assessment of moisture levels without the need for expensive electronic dewpoint meters.

• Japanese Quality: Manufactured under strict quality controls (QC No. 50747) to ensure consistent performance in every test.

• Field Ready: Compact and portable, it can be used with a 30-metre extension hose for sampling from difficult-to-reach valves or tanks.
