Description
Built for very high-concentration monitoring, the NextTeq NX119VVH detector tube offers a dual measuring range of 0.23–23% (half pump stroke) or 0.1–10.0% (full pump stroke), with a fast 2-minute sampling time and a detectable limit of 0.01%. 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 3-year shelf life, it's ideal for applications requiring detection of very high CO levels, such as fire investigation or industrial combustion monitoring.
