• The inlet apparatus type "Böhme" is designed for the determination of the bulk density of building lime according to EN 459-2.

    The inlet instrument consists of a cylindrical container made of brass with a volume of exactly one liter, an adaptor flange with shutter and a top mounted filling device with release lever. After pouring the bulk goods into the top mounted filling device the shutter is opened and the goods drop into the container. Then the surplus goods are skimmed and the weight is measured.

     

    Design

    The inlet apparatus consists of a cylindrical container made of brass with a volume of one liter, an adaptor flange with shutter, and a top mounted filling device with shutter activating lever.
  • The plasticity tester is designed for the determination of the workability of ceramic materials. The plasticity value according to Pfefferkorn is determined by measuring the plasticity of a specimen between a fixed lower bearing plate and a free falling upper brass plate. Advantages ✓ Reliable evaluation of characteristic values ✓ Simple operation
  • Operating Principle

    The viscosity tester type Lehmann is designed to determine the viscosity of glazing and clay slips. The time is measured that a defined amount of test material needs to run through a nozzle with a specific cross section into a volumetric flask. Subsequently the viscosity value can be determined comparing the time with such a slip of known consistency needs.

    Advantages

    ✓ High repeatability ✓ High accuracy ✓ Simple technique and handling ✓ Simple and quick measuring procedure (advantageous for test series and quality control)
