TA750SN / VT650ST / VT170SO - device combination
comprising Thermo-Analysis / VAC-Test / Density Index Analysis

This IDECO TA & VT device combination contains three systems that are connected to each other in a modular way:

The IDECO Thermo-Analysis TA750SN, the VAC-Test System VT650ST and the Density Index Analysis System VT170SO.


The IDECO® Thermo-Analysis system, is a qualitative measuring system for the simple determination of grain refining and the modification of liquid aluminium alloys. The system records the cooling process of a metal sample in detail and analyses it automatically. The temperature acquisition and measurement results are graphically displayed.

  • All measurements are identified and documented.
  • It is designed as a mobile device for flexible use in production operations.
  • The sensor technology is calibrated by IDECO as standard with a certificate and seal.
  • The sample ingots and temperature sensors used are reusable, therefore conserving resources and reducing costs.
  • A (one-handed lever) device for precise positioning and for lowering again afterwards enables the safe and simple use of the thermal sensor.
  • Fan cooling of the sample ingots to room temperature guarantees consistent testing success and a good level of reproducibility.
  • The IDECO Thermo-Analysis system is network-compatible as standard and therefore offers every possibility for integration into the in-house QA system and for further processing of the data (e.g. with the IDECO "QS-Master" software) to facilitate evaluation of the measurements in even greater detail (derivative functions, energy coefficients, comparison curve analysis, magnification) (see also Quality Management / Software).

VAC-Test & Density Index Analysis System

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.

  • Quick and easy determination of the melt quality by the caster
  • The sample crucibles are reusable.
  • Combining the VAC-Test System for sample preparation and the Density Index Analysis System in one device enables quick and centralised operation.
  • Fan cooling of the sample crucibles to room temperature guarantees consistent testing success
  • Infinitely variable working vacuum for precise vacuum setting.
  • The scales and vacuum technologies are calibrated by IDECO as standard with a certificate and seal.
  • The system is designed as a mobile device for producing "density index" samples, and is ideal for flexible use in production operations.

Tabular overview of the current measurements with sample identification and measurement result.

User-related identification of each measurement (e.g. "article", "customer", "batch", "furnace", "alloy", etc.) with plausibility check

Self-configurable selection or validation lists can simplify sample identification and avoid input errors.

Automatic measured value identification for frequently recurring entries, e.g. for follow-up measurements 

Automatic recording and analysis of the cooling process of the metal sample with simultaneous graphic display

Detailed graphic display of the measurement result with indication of the points with thermal relevance. This enables verification of the measurement result.

Search and filter function for all stored measurements

Thermo-analysis measurements can be subsequently supplemented with additional data (e.g. VAC-Test / spectral / temperatures) and a comment

VAC-Test measurements can also be documented separately (without thermo-analysis measurement)

Printout of measurements on a local or network printer (if available)

Customised software adaptations are of course possible

Secured system ("kiosk mode"). No access to the operating system for the operator

Manual backup of measurements on USB data carrier

Further individual functionalities are possible when connected to a network, e.g.:

  • Import of master data to facilitate or secure identification input
  • Import of alloy-related or article-related min./max. target values for results evaluation
  • Automatic transfer of additional data from other devices (e.g. spectral analysis)
  • Automatic export of measurement results to a CSV file
  • Automatic data backup to a network folder
