Description
Detect low-level sulfur dioxide (SO₂) with the NextTeq NX211L detector tube, offering a dual measuring range of 0.5–10 ppm (single pump stroke) or 0.25–5 ppm (two pump strokes) with a detectable limit of 0.1 ppm. This tube reacts with sulfur dioxide to shift from pink to yellow, with results read directly off the printed scale calibrated for one pump stroke and adjusted using the included humidity correction table. With a TLV-STEL of 0.25 ppm and a 1-year shelf life when stored refrigerated, it's a precise solution for monitoring trace-level SO₂ exposure.
