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.

Models for all 20mm Sensors

• TC-1 - 3 mm side mounted ports

Models for Sensors on MX Boards

Use with sensors on MX boards only. Ribbon cable connects to the PCB to measure barometric pressure, temperature, and % relative humidity levels in gas sample.

• TC-4 - 3 mm side mounted ports away from sensor
• TC-5 - 3 mm side mounted ports towards sensor

Works with:

• LuminOX LOX-02 25% Oxygen Sensor Devkit
• ExplorIR®-M 5% CO2 %RH/T Hg Sensor
• ExplorIR®-M 20% CO2 %RH/T Hg Sensor
• ExplorIR®-M 100% CO2 %RH/T Hg Sensor
