Many of you have called us to ask about applications that start with the sentence, “How do I…” In every case, the application falls into one of two groups: measuring gas by diffusion or measuring gas by sampling. Knowing the difference can help you decide which method is best for you. Diffusion – Measurement for Environment From indoor air quality to plant growth to personal safety: all of these involve people and areas where gases are diffused in ambient air. In other words, the sensor measures the gas concentrations diffused around it. Since the sensor is physically in the ambient...

With the drastic increase in bedbug infestation over the last several years, scientists and researchers have searched for safe, cost-effective methods of eliminating these pests. Because bedbugs are attracted by the elevated carbon dioxide levels in human respiration, CO2 can be used to determine if a bedbug infestation exists. And because high levels of CO2 kills bed bugs, pest control companies are using CO2 instead of toxic insecticides to fumigate hotel rooms and even entire buildings. Bedbugs can live for months between feedings. When a bedbug senses a rise in CO2 levels, it will follow the CO2 to its source....
