1. A water-proof electrochemical sensor for in situ analysis of a liquid analyte comprising:

  • an electrode body for contacting the analyte having an upper contact end and lower sensing end;

    a collar attached to said electrode body in the vicinity of the upper contact end;

    at least one electrochemical sensor contained within said electrode body an extending from the lower sensing end for contacting the analyte;

    a contact for electrically connecting said at least one electrochemical sensor to external electronics extending from the upper contact end; and

    a resilient elastomeric generally cylindrical boot having an upper end and a lower end and an internal groove adapted to press-fit the collar, the upper end of the boot having an opening adapted to form an interference fit with the pin contact and the lower end of the boot having an opening adapted to form an interference fit with the electrode body whereby a water-proof seal is formed around the upper contact end of the electrode body.
