Abstract: An electronic weighing machine for a moisture meter not only measures the amount of moisture in the test sample, but also measures the mass of the test sample itself. In addition, the present invention is related to a heat drying type moisture meter, a filter for the moisture meter and a moisture adsorption unit for the moisture meter. The electronic weighing machine for the moisture meter is used with the moisture meter which is equipped with a heating section for introducing the carrier gas into it and heating the test sample, a moisture adsorption section for adsorbing the vaporized moisture from the carrier gas flowing out of the heating section, and an electronic weighing section for determining the increase in mass of the moisture adsorption section. The electronic weighing section has a test sample weighing section and a section for measuring the mass of the collected vaporized moisture in the weighing arm of the electronic weighing unit.

Abstract: A heating unit vaporizes a sample placed in a container having an opening that is hermetically sealed with a rubber gasket and discharges the vaporized constituents to the outside of the container together with a carrier gas. A sample 16, such as an easy-to-vaporize liquid, is placed in a container 1 whose opening 1a is hermetically sealed with a rubber gasket 2a. The container 1 is loaded into a heating tube 8 to extract the vaporizable constituents. The heating tube 8 is equipped with carrier gas introduction tubes 12 having needles 4 with through-holes, a vaporized constituent and carrier gas discharge tube 13 having a needle 5 with a through-hole, and a heater 11. These needles 4 and 5 are arranged to pierce the rubber gasket 2a of the container 1 placed in the heating tube 8.
