Description
Detect high concentrations of sulfur dioxide (SO₂) with the NextTeq NX211H detector tube, offering a 0.1–3.0% measuring range with a detectable limit of 0.01% (100 ppm) using a single pump stroke. This tube reacts with sulfur dioxide to shift from yellow to blue, with results read directly off the printed scale calibrated for one pump stroke. With a TLV-STEL of 0.25 ppm and a 3-year shelf life, it's well-suited for monitoring elevated sulfur dioxide levels in industrial applications.
