Measuring the purity and concentration of CO2 in air or nitrogen
Accurate measurement of CO2 concentration in the air and determination of CO2 in decarbonisation projects are crucial for monitoring and controlling emissions. Thermal conductivity meters from Archigas offer high precision and sensitivity, making it possible to detect even small changes in CO2 levels. This is particularly important for compliance with environmental regulations and optimising processes to reduce greenhouse gas emissions. An advantage of CO2 concentration measurement with Archigas is a linear signal over the entire measuring range (0-100 vol.%) as well as the long service life of the sensors up to 10 years.
Measurement of the gas purity of N2, He, O2, H2, Ar
Determining the purity of gases such as nitrogen (N2), helium (He), oxygen (O2), hydrogen (H2) and argon (Ar) is of great importance in many branches of industry. Archigas gas analysis makes it possible to measure the purity of these gases with the highest accuracy. This is essential for applications in electronics manufacturing, medicine, food processing and other areas where gas purity directly affects product quality. Archigas solutions ensure that the gases used always meet the highest purity standards.
