Gastec Mercaptans (R . SH) Detector Tube – No. 70L

Precision Detection for Odorant Levels and Process Safety

The Gastec No. 70L detector tube is designed for the rapid measurement of Mercaptans in air or gas streams. Whether you are verifying the concentration of odorants in a natural gas pipeline or monitoring for industrial leaks, this tube provides a reliable, high-sensitivity reading in minutes. It is an essential component for safety protocols in gas distribution and chemical manufacturing.

Key Features

• Multi-Substance Capability: While labeled for general Mercaptans, this tube is validated to measure specific compounds including Methyl, Ethyl, Propyl, Butyl, and tert-Butyl mercaptans.

• High Sensitivity: Designed for trace analysis with a measurement range starting at 0.1 ppm.

• Clear Colorimetric Results: The chemical reagent provides a distinct color change from Yellow \rightarrow Reddish Pink, making it easy to confirm gas presence at a glance.

• Direct Scaling: Features a pre-printed scale on the glass for immediate results without requiring external laboratory analysis.

• Japanese Precision: Built under strict quality standards (QC No. 40573) to ensure repeatability and accuracy in every test.
