GASTEC Sulphur Dioxide (SO2) Detector Tubes – Multiple Measurement Ranges

GASTEC Sulphur Dioxide (SO2) Detector Tubes

GASTEC Sulphur Dioxide Detector Tubes provide a convenient, direct-reading method for measuring sulphur dioxide (SO2) concentrations in air and gas samples. Designed for use with a compatible GASTEC gas sampling pump, these colorimetric detector tubes allow professionals to perform rapid on-site SO2 measurements across a wide range of concentrations.

With available measurement ranges extending from 0.05–10 ppm to 0.05–8% sulphur dioxide, GASTEC offers multiple SO2 detector tube options for applications ranging from low-level industrial hygiene and workplace air monitoring to high-concentration industrial and process measurements.

Choose the Sulphur Dioxide Detector Tube for Your Application

GASTEC offers multiple Sulphur Dioxide Detector Tubes designed for different SO2 concentration ranges. Select the appropriate GASTEC product number based on the anticipated sulphur dioxide concentration and the requirements of your sampling application.

GASTEC Product Number	Sulphur Dioxide Measurement Range
5H	0.05–8%
5M	20–3,600 ppm
5L	1.25–200 ppm
5LA	0.5–60 ppm
5LC	0.1–25 ppm
5LB	0.05–10 ppm

 

Direct-Reading Colorimetric SO2 Measurement

GASTEC detector tubes use chemical detection reagents that react with the target gas as a measured volume of sample is drawn through the tube. The resulting color-change layer provides a visual indication of sulphur dioxide concentration. The measurement can then be determined using the calibrated scale on the detector tube along with the sampling and correction instructions specified for the selected GASTEC product number.

This direct-reading method provides a practical solution for spot measurements, field screening, industrial hygiene surveys, process checks, environmental investigations, and troubleshooting where SO2 concentrations need to be evaluated directly at the sampling location.

SO2 Detector Tubes for Low to High Concentrations

The selection of GASTEC Sulphur Dioxide Tubes allows users to choose a measurement range that closely matches anticipated conditions. For low-level measurements, the GASTEC 5LB (0.05–10 ppm) provides the lowest available range in this selection, followed by the 5LC (0.1–25 ppm) and 5LA (0.5–60 ppm).

For higher ppm concentrations, the GASTEC 5L (1.25–200 ppm) and 5M (20–3,600 ppm) provide progressively higher measurement capabilities. For applications involving percentage-level sulphur dioxide concentrations, the GASTEC 5H (0.05–8%) provides the highest concentration range in this product selection.

Important Range Selection Information

Because sulphur dioxide concentrations can vary substantially between applications, select a detector tube appropriate for the anticipated concentration before sampling. Individual GASTEC product numbers may have different sampling volumes, pump strokes, sampling times, temperature requirements, correction factors, and potential interfering gases. Always follow the instructions provided for the specific detector tube being used.
