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 .
includes all the tools you need to urilize the tube-cap adapters as part of a sampling sensor system.
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.
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.
Sensor Pin Sockets - Manufacturers do not recommend soldering to the pins. Pin sockets can be purchased from Andon Electric. .
