GASTEC Carbon Dioxide (CO2) Detector Tubes – Multiple Measurement Ranges

GASTEC Carbon Dioxide (CO2) Detector Tubes

GASTEC Carbon Dioxide Detector Tubes provide a convenient, direct-reading method for measuring carbon dioxide (CO2) concentrations in air and gas samples. Designed for use with a compatible GASTEC gas sampling pump, these colorimetric detector tubes allow users to obtain on-site CO2 measurements without requiring electronic gas detection equipment or laboratory analysis.

With available measurement ranges extending from 100–4,000 ppm to 10–100% carbon dioxide, GASTEC offers multiple CO2 detector tube options for applications ranging from lower-concentration air monitoring to high-concentration industrial and process measurements.

Choose the Carbon Dioxide Detector Tube for Your Application

GASTEC offers multiple Carbon Dioxide Detector Tubes for measuring CO2 across a wide range of concentrations. Select the appropriate GASTEC product number based on the expected carbon dioxide concentration in your application.

GASTEC Product Number	Carbon Dioxide Measurement Range
2HT	10–100%
2HH	2.5–40%
2H	0.5–20%
2L	0.13–6%
2LL	300–5,000 ppm
2LC	100–4,000 ppm

 

Direct-Reading Colorimetric CO2 Measurement

GASTEC detector tubes use a chemical reagent that reacts with the target gas as a measured volume of sample is drawn through the tube. The reaction produces a visible color-change layer, allowing the carbon dioxide concentration to be determined using the calibrated scale on the tube and the instructions provided for the selected tube model.

This straightforward measurement principle makes GASTEC Carbon Dioxide Tubes particularly useful for field screening, workplace assessments, industrial troubleshooting, process checks, and other applications where users need a rapid indication of CO2 concentration at the sampling location.

Multiple CO2 Ranges for Low and High Concentrations

The range of available GASTEC Carbon Dioxide Tubes makes it possible to select a detector tube suited to the expected CO2 concentration. For lower-concentration measurements, the GASTEC 2LC (100–4,000 ppm) and 2LL (300–5,000 ppm) provide ppm-level measurement ranges.

For higher concentrations, the 2L (0.13–6%), 2H (0.5–20%), 2HH (2.5–40%), and 2HT (10–100%) provide progressively higher percentage-based CO2 measurement ranges. This selection allows users to choose a GASTEC detector tube that more closely matches the anticipated concentration at the sampling location.
