Description
Detect ethyl benzene (C₆H₅CH₂CH₃) with the NextTeq NX149 detector tube, offering a 10–500 ppm measuring range with a detectable limit of 3 ppm using a single pump stroke. This tube reacts with ethyl benzene to shift from white to brown, with results read directly off the printed scale calibrated for one pump stroke. With a TLV-TWA of 20 ppm and a 1.5-year shelf life, it's a reliable choice for monitoring this common aromatic hydrocarbon used in styrene and plastics production.
