VT650ST/VT170SO Mobile Compact Device
For the production and analysis of "density index samples"

The IDECO VAC-Test & Density Index device is a system for simple determination of the pore potential of liquid aluminium alloys. In order to determine the actual pore potential, a sample is taken from the melt to be tested using a sampling ladle. After casting in two special sample crucibles, one sample solidifies at atmospheric pressure and one at 80 mbar absolute pressure.

Once the samples have cooled down, the density index is determined on the Density Index Analysis System according to Archimedes' principle. The density index represents the percentage density difference of the two samples created.

• The preparation of the samples and the DI determination in this compact device allows fast and centralised operation directly at the crucible or furnace.
• Quick and easy determination of the melt quality by the caster
• The sample crucibles are reusable.
• Fan cooling of the sample crucibles to room temperature guarantees consistent testing success
• Infinitely variable working vacuum for precise vacuum setting.
• The vacuum and weighing technology is calibrated by IDECO as standard with a certificate and seal.
• Designed as a compact and mobile device combination for producing analysing "density index" samples, and ideal for flexible use in production operations.
• Optional vacuum monitoring is possible
• Also available as a "table-mounted device" without base frame
• The new VAC-Test System VT650 and Density Index Analysis System VT170 module series allow direct or retrospective combination with an IDECO Thermo-Analysis device from the TA750 range. Alternatively, the system can also be equipped with an IDECO Hydrogen-Analyser from the HM330 range.
