A method for testing a measuring device is used to determine a permittivity of a frying fat which permittivity is inter alia dependent on the temperature, while taking into consideration the temperature. The method is characterized in that the permittivity is measured at least two different temperatures and the temperature dependence is determined and is used to make a statement on the ability to function of the measuring device.

Method for testing a frying oil tester

In a gas sensor with at least two electrodes and with a sensor body which is connected thereto and is composed of a gas-sensitive material, in addition to pores which may already be present, second cavities are provided in the sensor body. The second cavities may be suitable on account of their size to facilitate and accelerate the distribution of gas molecules in the sensor body and to thus improve the time response of the gas sensor.

Gas sensor and method for its production

A measuring device is used to measure the state of oils of fats. Said measuring device comprises a housing, a hollow connecting element which is secured therein and a carrier which is applied to the opposite end of the connecting element, said carrier being used to receive a sensor which can be used to measure an electric property of the product which is to be measured. The sensor is in contact with an evaluation unit by means of at least one electric line which is arranged on a non-conductive carrier, which is arranged in the region of the housing and/or the end of the connecting element which is oriented towards the housing. The measuring device comprises a plurality of carriers which are arranged in a row and which are thermally insulated from each other.

Measuring device for measuring the state of oils or fats

A measuring device is used to measure the state of a liquid product which is to be measured, in particular oil or fat. Said measuring device comprises a housing, a hollow connecting element which is secured therein and a carrier which is applied to the opposite end of the connecting element, said carrier being used to receive a sensor which can be used to measure the electric property of a product which is to be measured. The sensor is in contact with the measuring unit by means of at least one electric line, which is arranged in the region of the housing and/or with the end of the connecting element oriented towards the housing. The measuring device comprises means which can be used to minimize the falsifying effect of the water content in the product, which is to be measured, on the measuring result.
