Vaisala uses Humicap sensor technology for measuring moisture in oil. The Humicap sensors are the first ever sensors that can measure moisture in oil online. The sensor materials are specifically developed to measure even very low moisture levels in oils, whether mineral, vegetable or synthetic. The Vaisala Humicap is manufactured in Vaisala clean rooms and is a thin film sensor consisting of a substrate on which a thin polymer is deposited between two conductive electrodes.
