GASTEC Nitric Acid (HNO3) Detector Tube 15L – 0.1–40 ppm

GASTEC Nitric Acid (HNO3) Detector Tube 15L

The GASTEC 15L Nitric Acid Detector Tube provides a convenient, direct-reading method for measuring nitric acid (HNO3) concentrations in air and gas samples. Designed for use with compatible GASTEC gas sampling equipment, this colorimetric detector tube provides a measurement range of 0.1–40 ppm for rapid on-site nitric acid testing.

The GASTEC 15L is well suited for industrial hygiene, workplace air monitoring, chemical processing, laboratory, manufacturing, and field applications where nitric acid concentrations need to be evaluated directly at the sampling location.

GASTEC Product Number	Target Substance	Measurement Range
15L	Nitric Acid (HNO3)	0.1–40 ppm

 

Direct-Reading Colorimetric Nitric Acid Measurement

GASTEC detector tubes use chemical detection reagents that respond to the target substance as a measured volume of sample is drawn through the tube. The resulting color-change layer provides a visual indication that can be interpreted according to the calibrated tube scale and operating instructions for the GASTEC 15L.

This direct-reading method provides a practical option for spot measurements, industrial hygiene surveys, workplace assessments, process checks, maintenance investigations, and field screening without requiring an electronic sensor at the detector tube.

0.1–40 ppm HNO3 Measurement Range

The GASTEC 15L measures nitric acid over a range of 0.1–40 ppm. This range supports measurements across low and moderate HNO3 concentrations and provides a convenient option for applications where rapid on-site nitric acid measurement is required.
