Abstract
Abstract Electrochemical sensors that are disposable, precalibrated and capable of measuring a single or multiple parameters are disclosed. The sensors can be mass produced and are designed to be operated by personnel with a minimum of skills. The sensors are packaged in substantially water and oxygen impermeable containers and are particularly designed for use in the medical field to measure various ions or other species in body fluids.
