Carbon dioxide (CO2) testing refers to the process of measuring the levels of carbon dioxide gas in a particular environment or substance. This testing is often performed for various purposes, including environmental monitoring, safety assessments, and industrial processes.
Gas Analyzer: Gas analyzers are devices specifically designed to measure the concentration of various gases, including carbon dioxide. They utilize sensors or detectors that can detect and quantify the presence of CO2 in the air. These analyzers provide real-time measurements and are commonly used in industries, laboratories, and environmental monitoring.
Colorimetric Tubes: Colorimetric tubes are simple, portable devices used for on-the-spot analysis of carbon dioxide levels. These tubes contain a chemical reagent that changes color when exposed to carbon dioxide. By attaching a hand pump to the tube and drawing a known volume of air through it, the color change can be observed and matched to a calibrated scale to determine the CO2 concentration.
