The Mobile Test Unit ALSP plus is used to determine the quality of the melt based on the measurement of the density index.

Information on process:

The ALSP plus which has the added advantage of a crucible pre-heating chamber, is designed to maximise the efficiency and convenience of working processes. The special shelf for the pouring ladle (supplied with the unit) and the water vessel for cooling the samples (set into the working surface) are situated conveniently close to the operator. The Density Index Balance MK 3000 stands on the test unit, but can be moved to a different location if required. The unit's sub-frame has three large storage compartments. The smooth-running and heat-proof wheels make the ALSP plus a flexible and versatile aid at the different casting stations or furnaces.

Special features:

  • Flexible use at different casting stations or furnaces
  • Convenient and efficient working
  • Vessel for cooling density samples provided
  • Shelf and storage space
  • Process reliability through fully electronic control:
  • - fully automatic control of vacuum to 80 mbar
    - leakage indicator
    - cycle counter
  • Fewer incorrect readings and greater accuracy of measurement through use of crucible pre-heating chamber
  • Exact calculation of density to four decimal places (0,0000 g/cm³)
  • Interface for transfer of density index results to:
  • - PC Software supplied
    - optional Memory Box
  • Capable of 100% calibration
  • CE conformity
  • Tested to DGUV standard

The PC Software supplied permits the following operations:

  • Saving of measurements
  • Use of statistical process control (SPC)
  • Analysis and assessment of data by means of various filters for the density index results
  • Printable reports
  • Results exportable to MS Excel
