Abstract: A sample stream is conditioned by the addition of reagents and the ion concentration is measured by means of a measuring system which can be connected to an arrangement for releasing an appropriate calibrating substance.

Abstract: A highly accurate and miniaturized pressure transducer is disclosed which includes first and second capacitors as a part of the integrated circuit, which also includes an Eccles-Jordan astable multivibrator. The miniaturization of both the capacitors and the entire multivibrator circuit in an integrated circuit establishes all components so that they are very closely matched on the two halves of the multivibrator, and so that whatever environmental disturbances, e.g., electrical, thermal, noise, etc., are encountered, are shared by both halves, and hence negated, so far as output drift is concerned.
