Gastec Carbon Dioxide (CO₂) Gas Detector Tubes provide a convenient method for measuring carbon dioxide concentrations in air using a compatible Gastec gas sampling pump.

Designed for on-site gas detection, industrial hygiene, workplace air monitoring, occupational safety, and environmental testing, Gastec detector tubes provide a simple visual method for measuring specific gas concentrations without requiring electronic gas detection equipment.

Multiple measuring ranges are available to accommodate a wide variety of carbon dioxide monitoring applications, from lower PPM-level concentrations to high percentage-level CO₂ measurements.

Common Applications

Gastec Carbon Dioxide Gas Detector Tubes can be used with compatible Gastec sampling equipment for workplace air monitoring, industrial hygiene surveys, occupational exposure assessment, indoor air quality testing, confined space monitoring, food and beverage processing, breweries and fermentation operations, laboratories, manufacturing facilities, environmental monitoring, process monitoring, and workplace safety applications where carbon dioxide may be present.

Important

A compatible Gastec Gas Sampling Pump is required to use these detector tubes. Always select the appropriate detector tube and measuring range for your target gas and follow the manufacturer's sampling instructions and correction factors, when applicable, for the specific tube being used.
