The HI-4005-53 replacement membrane kit contains 3 membrane caps with pre-formed PTFE membranes for the carbon dioxide gas sensing ISE. When the carbon dioxide ISE is first being assembled, or after a membrane is worn, the HI-4005-53 membrane kit allows for easy assembly and replacement. By simply screwing on the pre-assembled cap and membrane, the sensitive PTFE membrane will remain dry and undamaged for more reliable, accurate measurements.
