The device for accelerated determination of humidity: model 062M3 is designed for drying samples of mixtures in the process of determining humidity in shop, factory laboratories, as well as in laboratories of research organizations.
Components of the device
The device consists of a metal base on which laboratory electronic scales are installed with a maximum limit of weighing cargo on a cargo receiving platform up to 300 g. A folding metal housing is attached above the cargo receiving platform, in which a halogen heater is located. An electric heat-resistant cord fits to the back wall of the housing, on which a two-position switch of a halogen lamp is located.
The principle of operation of the installation
The device is switched on by pressing the "ON" button. The scale on the display should show the number "0", otherwise press the "ON" button again. During operation, an empty container (aluminum cup) is installed on the load-receiving platform of the electric scales. By pressing the button, we "reset" the container. We pour a weight of 10-20 g into the container. By pressing the button 2 times, we will enter the percentage mode. We turn on the halogen lamp using a two-position mains switch on the cord, which is conditionally considered the beginning of heating (drying of the suspension). The end of heating is considered to be the stabilized value of % humidity on the display.
