SVM II Tapped Density Tester

The SVM II is the latest generation of tapped density testers from ERWEKA. With unprecedented flexibility and intelligent features, it makes tapped density testing easy and reliable.

The 7“ high resolution touch display with modern interface focuses the user on the most important task tapped density testers have to fulfil – 100% USP/EP compliant tapped density testing. With the automatic calculation features of the Test Assist, the user is guided step-by-step through the testing process as quickly as possible. It also automatically calculates the Hausner Ratio and compressibility index and prints the reports after every test.

In addition to its ease of use, the SVM II is the most flexible tapped density tester we have ever sold. The intelligent Switch Plate system enables 5 different versions of the SVM II, with both USP 1 and USP 2 in either one or two test station configurations or a combination of both methods. And the best part – they can also be upgraded at a later date!

The SVM II also supports a variety of method and norms: From USP 1 and USP 2 to ASTM B527-15 and DIN EN ISO 787-11:1995 – with the SVM II, users are on the safe side of valid and conforming tapped density testing.

SVM Switch Plates – Five plates for one tester!

The SVM offers five different Switch Plates that can be interchanged, making it possible to upgrade a single SVM with a new Switch Plate whenever required.

The new Switch Plate system offers maximum flexibility and makes every SVM II absolutely futureproof.

Installing a SVM II Switch Plate is a two step process – first the user changes the plate on the SVM II by fixing it with 6 small screws. The next step is done in the configuration panel – the activation code needs to be entered, which is part of the purchase of a Switch Plate. This activates the specific Switch Plate in the Test Assist and report engine of the SMV II.

The following Switch Plates are available:

  • USP 1 with 1 station
  • USP 1 with 2 stations
  • USP 2 with 2 station
  • USP 2 with 2 stations
  • 2 Test station combination with USP 1 and USP 2

Digital Interface

The touch interface of the SVM II focuses the user on the most important task to be done with the SVM II: tapped density testing. The central part is the Test Assist, an intelligent assistant with real-time feasibility checks that provides support and guarantees the conformity of the entered parameters according to USP/EP/JP. When testing according to USP methods, Test Assist prompts the user to enter the required values. Afterwards, it then computes the results for Tapped Density, Hausner Ratio and Compressibility Index completly automatically. Tapped density testing thus becomes simple and safe. All other functions, such as the control panel, the qualification menu and the service menu are also designed to connect user and hardware as quickly as possible.
