GASTEC Nitrogen Dioxide (NO2) Detector Tube 9L – 0.2–12 ppm

GASTEC Nitrogen Dioxide (NO2) Detector Tube 9L

The GASTEC 9L Nitrogen Dioxide Detector Tube provides a convenient, direct-reading method for measuring nitrogen dioxide (NO2) concentrations in air and gas samples. Designed for use with compatible GASTEC gas sampling equipment, this colorimetric detector tube provides a measurement range of 0.2–12 ppm for rapid on-site NO2 testing.

The GASTEC 9L is well suited for industrial hygiene, workplace air monitoring, combustion-related investigations, environmental testing, manufacturing, process monitoring, and maintenance applications where nitrogen dioxide concentrations need to be evaluated directly at the sampling location.

9L	Nitrogen Dioxide (NO2)	0.2–12 ppm

Direct-Reading Colorimetric NO2 Measurement

GASTEC detector tubes use chemical detection reagents that respond to the target gas as a measured volume of sample is drawn through the tube. The resulting color-change layer provides a visual indication that can be interpreted using the calibrated tube scale and operating instructions for the GASTEC 9L.

This direct-reading approach provides a practical solution for spot measurements, workplace assessments, industrial hygiene surveys, environmental investigations, process checks, and maintenance activities where rapid nitrogen dioxide measurement is required.

0.2–12 ppm Nitrogen Dioxide Measurement Range

The GASTEC 9L measures nitrogen dioxide across a range of 0.2–12 ppm. This focused measurement range makes the tube useful for applications where relatively low concentrations of NO2 are anticipated and on-site measurement is preferred.

Because nitrogen dioxide may be associated with combustion processes and a variety of industrial operations, portable detector tube testing can provide a useful method for investigating specific locations, processes, equipment, or work areas.
