Description
The Nextteq Bromochloromethane Tube No. NX180M provides flexible measurement over two ranges—2–80 ppm with a single 100 mL pump stroke (direct scale reading) and 20–400 ppm with a ½ stroke (50 mL) using a simple conversion chart—and a clear white-to-yellow color change, with the tube scale calibrated on methyl bromide. With a 3-year shelf life when stored under refrigerated conditions (32–50°F), a narrow 59–77°F operating range, and calibration by gas chromatography, this tube is well suited for workplace and process monitoring of bromochloromethane, even though no TLV value is currently listed (TLV: N/A), noting that halogens and halogenated hydrocarbons can produce similar stains and lead to higher readings.
