GASTEC Hydrogen Fluoride (HF) Detector Tubes – Multiple Measurement Ranges

GASTEC Hydrogen Fluoride (HF) Detector Tubes

GASTEC Hydrogen Fluoride Detector Tubes provide a convenient, direct-reading method for measuring hydrogen fluoride (HF) 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 HF measurements across multiple concentration ranges.

Three measurement options are available, covering hydrogen fluoride concentrations from 0.05 ppm up to 100 ppm. This range selection makes it easier to choose a detector tube suited to lower-level measurements, broader workplace air assessments, or industrial process applications where higher HF concentrations may be encountered.

Available Hydrogen Fluoride Detector Tubes

GASTEC Product Number	Target Gas	Measurement Range
17	Hydrogen Fluoride (HF)	0.25–100 ppm
17L	Hydrogen Fluoride (HF)	0.09–72 ppm
17LL	Hydrogen Fluoride (HF)	0.05–24 ppm

 

Direct-Reading Colorimetric HF Measurement

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

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

Choose the HF Measurement Range for Your Application

The GASTEC 17LL provides the lowest available measurement range at 0.05–24 ppm, making it the most sensitive option in this selection. The GASTEC 17L covers 0.09–72 ppm, providing a broader measurement range while retaining low-ppm capability.

For applications requiring measurement across a wider concentration range, the GASTEC No. 17 measures hydrogen fluoride from 0.25–100 ppm. The overlapping ranges allow users to select the detector tube that most closely matches the anticipated HF concentration and sampling requirements.

Important Range Selection Information

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