| Abstract: | Summary The first specimens of the described apparatus were produced by the Etalon Plant of the VNIIM in high-temperature performance, and they were thoroughly tested. Thanks to their compactness, convenience in operation, and high checking accuracy, the apparatuses will undoubtedly find a wide application in the laboratories of the Committee system and in control laboratories of metallurgical plants.The process of testing with both apparatuses is considerably speeded up thanks to a rational selection and arrangement of standard measuring instruments built into the apparatus, switching and regulating devices, and also thanks to the application of the semi-automatic standard R2-A potentiometer ZIP model.According to sources in literature, an apparatus for testing secondary instruments has not been developed abroad.The drawings of the apparatus are presently being handed over to a number of organizations in order to bring about its production in series. |
