36.874 is a field of application that is used for the precise control and measurement of humidity in the production of food products. This is done to maintain the stability and freshness of the product throughout its shelf life.

Humidity measurement is used in many industries, such as manufacturing, brewing, food storage, and shipping. In these industries, maintaining the correct relative humidity or RH is important to ensure product safety and quality. It is also important for climate control in confined spaces such as greenhouses, storerooms, or food production areas.

The working principles of 36.874 are based on the fact that the resistivity of certain materials is affected by changes in relative humidity. This property of hygroscopic materials can be used to measure humidity in air, and this has been utilized in various ways for decades. The most common methods use capacitive, resistive, or optical sensors to measure the electrical or optical properties of hygroscopic materials.

Capacitive sensors are commonly used in humidity measurements as they can detect changes in the electrostatic capacitance of a material caused by variations in moisture content. These devices use two electrodes which are separated by a thin layer of hygroscopic material, typically in the form of a thin film. The capacitance between the two electrodes changes depending on the relative humidity and can be used to measure the humidity in the environment.

Resistive sensors are also used to detect changes in humidity, but these devices work on a different principle. These sensors measure the change in resistivity of a hygroscopic material in response to variations in the relative humidity. The change in resistivity is proportional to the amount of moisture in the air, and this can be used to measure the relative humidity.

Optical sensors are based on the optical properties of hygroscopic materials. These materials show a change in their optical properties in response to changes in the relative humidity. For example, when the relative humidity increases, the optical transmissivity of certain hygroscopic materials will decrease. The change in optical transmissivity is proportional to the moisture content, and thus can be used to measure the relative humidity.

The 36.874 field of application and working principles are used in many industries where it is necessary to measure and control the relative humidity. These principles are the basis of many commercial humidity measuring devices, and provide accurate and reliable measurements of humidity. By using these principles, manufacturers and other professionals are able to ensure the safety and quality of their products, and keep their customers satisfied and coming back for more.
