Description
Designed for high-concentration monitoring, the NextTeq NX119VH detector tube measures carbon monoxide across a 0.1–2.0% range with a single pump stroke and a detectable limit of 0.02%. This tube uses an iodine pentoxide reaction, shifting from white to dark brown, with results read directly off the printed scale calibrated for one pump stroke. With a 1-year shelf life and 5–10% accuracy across its range, it's well-suited for applications requiring high-level CO detection beyond typical ppm ranges.
