Abstract
A sensor apparatus is provided that is the sensor with or without accompanying sample collector means and calibration means in a hermetically sealed layer that contains at least one preconditioning fluid. The preconditioning fluid is an activating fluid when the sensor is in an unsealed housing and can be either or both the activating fluid or a controlled-content fluid when the sensor is in a sealed housing. The sealed housing is one that has the preconditioning fluid sealed in fluid contact with the one or more sensors on a sensor element. The sensor element also has an electrical circuit means in electrical contact with the one or more sensor on a nonconducting substrate. When both preconditioning fluids are present the activating fluid is in fluid contact with the one or more sensors in the sealed housing and the known-content fluid is present in the atmosphere in the hermetically sealed layer outside the sealed housing. The sealed layer is impervious to gas and moisture and is a diffusion-tight boundary or barrier.
