The tube cap kit is designed to transform the K-30 or the K-33ELG sensor from a diffusion-type sensor into a remote sensor.
The tube cap kit attaches directly to the top of the sensor with two self-tapping screws.
If you use the tube cap kit, you must also supply a vacuum of 0.3 liters per minute flow on one of the fittings in order to properly read the CO2 levels.
