Abstract:
(EN) A conductivity meter for measuring the conductivity of a sample of non-aqueous liquid. The conductivity meter includes a conductivity cell which contains the sample and which is disposed within a heater block which can control the temperature of the sample and a pressure vessel which can control the surrounding pressure for the conductivity cell. A probe senses conductivity of the sample as a voltage is applied across the sample.
(FR) La présente invention concerne un dispositif de mesure de conductivité destiné à mesurer la conductivité d'un échantillon de liquide non aqueux. Le dispositif de mesure de conductivité comprend une cellule de conductivité qui contient l'échantillon et qui est disposée à l'intérieur d'un bloc chauffant qui peut réguler la température de l'échantillon, et un récipient sous pression qui peut réguler la pression ambiante pour la cellule de conductivité. Une sonde détecte la conductivité de l'échantillon au fur et à mesure qu'une tension est appliquée à travers l'échantillon.
