Description
Detect low-level chlorine (Cl₂) concentrations with the NextTeq NX122L detector tube, offering a dual measuring range of 0.1–2.0 ppm (single pump stroke) or 0.05–1.0 ppm (two pump strokes) with a detectable limit as low as 0.01 ppm. This tube reacts with chlorine to shift from white to pale purple, with results read directly off the printed scale calibrated for one pump stroke. With a 2-year shelf life and 5–10% accuracy across its range, it's a precise choice for monitoring chlorine at or near its 0.1 ppm TLV-TWA exposure limit.
