Materials testing Product Information Vicat Dry Vicat specimens are simply placed on the measuring station Applications Determination of Vicat softening temperature (VST) • of thermoplastics as per ISO 306 On completion of preheating under the influence of force, the displacement signals are zeroed (programcontrolled) and warming of the heating block at the preset rate is started. As soon as the required penetra‐ tion is attained at all stations, the heating is switched off and the test is ended. No more irritating oil fumes! Advantages and features Vicat Dry instruments feature easy, convenient opera‐ tion. Particular areas of use include research and devel‐ opment, goods inwards checks and production moni‐ toring. The oil-free measuring principle ensures clean, odor-free working conditions. The test sequence is completely automatic. Different versions of the instrument are available, with two or six testing stations according to requirements. Testsequence parameterization and measured-value display can be performed conveniently on a connected PC. The results of the Vicat Dry test display excellent agree‐ ment with those obtained using a conventional oil-bath instrument. The same is true of test-result consistency. Automatic test sequence Function description Once the heating block has reached the starting temperature, the specimens are positioned in the meas‐ uring stations, the instrument is closed pneumatically and the test weight specified in the standards is auto‐ matically applied. Re-cooling is started automatically; the specimens can afterwards be removed. Functions, elements and interfaces • built-in microprocessor-controlled electronics for temperature control and measured-value acquisition • fully automatic test-sequence • automatically controlled compressed-air re-cooling • connection for fluid cooling • safety thermostat • low heating of housing • safety switch prevents crush risk • serial interface for connecting a PC for test-control and data acquisition via Zwick Roell testing software • integrated compensation for heat expansion • integrated weight sets, 10N and 50N Re-cooling the heat-transfer liquid The instruments are equipped with compressed-air cooling as standard. If sufficiently cool compressed air is not available, the inst
