GASTEC Hydrogen Chloride (HCl) Detector Tubes – Multiple Measurement Ranges

GASTEC Hydrogen Chloride (HCl) Detector Tubes

GASTEC Hydrogen Chloride Detector Tubes provide a convenient, direct-reading method for measuring hydrogen chloride (HCl) concentrations in air and gas samples. Designed for use with compatible GASTEC gas sampling equipment, these colorimetric detector tubes allow professionals to perform rapid on-site HCl measurements across multiple concentration ranges.

Two measurement options are available, covering hydrogen chloride concentrations from 0.2 ppm up to 1,000 ppm. The GASTEC 14L provides a lower measurement range of 0.2–76 ppm, while the GASTEC 14M extends measurement capability from 10–1,000 ppm for applications where higher HCl concentrations are anticipated.

Available Hydrogen Chloride Detector Tubes

GASTEC Product Number	Target Gas	Measurement Range
14M	Hydrogen Chloride (HCl)	10–1,000 ppm
14L	Hydrogen Chloride (HCl)	0.2–76 ppm

 

Direct-Reading Colorimetric HCl Measurement

GASTEC detector tubes use chemical detection reagents that respond to hydrogen chloride 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 the operating instructions specified for the selected GASTEC product number.

This direct-reading approach provides a practical solution for spot measurements, workplace air assessments, industrial hygiene surveys, process checks, environmental investigations, and maintenance applications where hydrogen chloride concentrations need to be evaluated directly at the sampling location.

Choose the HCl Measurement Range for Your Application

The GASTEC 14L provides a measurement range of 0.2–76 ppm, making it the lower-range option for applications where relatively small concentrations of hydrogen chloride are anticipated.

For higher concentrations, the GASTEC 14M provides a measurement range of 10–1,000 ppm. The overlapping measurement ranges allow users to select a detector tube that more closely matches the expected HCl concentration and requirements of the sampling application.

Important Range Selection Information

Hydrogen chloride concentrations can vary substantially between applications, making selection of the appropriate detector tube important. Individual GASTEC product numbers may have different sample volumes, pump strokes, sampling times, temperature and humidity considerations, interfering gases, and correction factors. Always follow the instructions supplied with the specific GASTEC Hydrogen Chloride Detector Tube being used.
