    System Requirements

    • Windows XP SP2 or newer
    • Microsoft .Net 3.5 Runtime Libraries

    Tube cap adapters easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer. Tube cap adapters are not pre-installed. For accurate results you must mount the tube cap permanently.

    Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.

    Nafion tubing is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.

    Micro gas sampling pumps provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
