Abstract

A system for measuring electrical conductivity includes a fluid conduction measuring circuit and a temperature measuring element having at least one thermal contact portion with a temperature sensor and a temperature measuring circuit. A controller is configured to control the conduction measuring circuit and the temperature measuring element. A fluid circuit is configured to carry a fluid and has a wetted conductor inside a conductivity cell portion, the wetted conductor having a contact, external to the fluid circuit, for interfacing with the fluid conduction measuring circuit. Further, at least one temperature measurement portion has predefined thermal properties and is configured to touch the thermal contact portion. The controller controls the temperature measuring element and the conduction measuring circuit to generate and output at least one set of contemporaneous temperature and conduction measurements.
