The Nextteq 1,2‑Dichloroethylene Detection Tube (NX137) provides direct, on‑site measurement across a wide range of concentrations—from 42–840 ppm down to 4.2–84 ppm depending on pump‑stroke volume. With a fast 1.5‑minute sampling time, a distinct yellow‑to‑red color change, and a detectable limit of 0.5 ppm, it delivers reliable performance in industrial environments requiring rapid chlorinated‑solvent monitoring. The tube’s oxidizer‑based reaction produces hydrogen chloride, enabling accurate quantification, and includes temperature‑correction guidance for both cis‑ and trans‑isomers.
