Description
The Nextteq 1-Butanol Tube No. NX151 provides direct measurement of 1-butanol from 5–100 ppm using three 100 mL pump strokes (300 mL total) and a clear yellow-to-pale-blue color change, with the tube scale calibrated on Ethyl Cellosolve and 1-butanol concentrations determined via a simple conversion chart. With a 2 ppm detectable limit, 2-year shelf life, 32–104°F operating range, and temperature correction guidance, this tube is well suited for workplace and process monitoring relative to the 20 ppm TLV-TWA guideline, noting that alcohols and toluene can produce similar stains or affect readings in coexistence.
