Tube Cap Adapter for 20mm Gas Sensors

Tube cap adapters convert any industry standard 20mm gas sensor from diffusion to sampling sensors.  We offer 3 standard gas in-out tube caps that work with any 20mm gas sensor and 2 custom 20mm tube caps with ribbon cables for sensors on MX boards that have barometric pressure, temperature, and % relative humidity sensors on board. Verify the tube cap you need from the models below. Tube cap adapters are not pre-installed. For accurate results you must mount the tube cap permanently. This video shows you how.
