The stationary tabletop device 3VT plus is used for casting two samples for density-comparison purposes. One of the samples is cast at a defined vacuum of 80 mbar and the other at atmosphere pressure.

The tabletop device 3VT plus includes a crucible pre-heating chamber which allows the user to cast the samples under conditions which are constant. The reasons for this are as follows: 

  • incorrect measurements, which may be caused by the absorption of atmospheric moisture by the crucible coating, are avoided, and
  • the aluminium melt is prevented from cooling too quickly in the crucibles, thus preventing the formation of gas porosity (caused by atomically dissolved hydrogen), or to the extent necessary for the test.

The melt samples are then weighed and the density index is calculated by using the Density Index Balance MK 3000.

Special features:

  • Long life span due to the design which reflects the special requirements of the foundry
  • User-friendly design
  • Process reliability through fully electronic control:
  • - fully automatic control of vacuum to 80 mbar
    - leakage indicator
    - low voltage indicator
    - cycle counter
  • Fewer incorrect readings and greater accuracy of measurement through use of crucible pre-heating chamber
  • Capable of 100% calibration
  • CE conformity
  • Tested to DGUV standard
