DROPimage Software

The ramé-hart DROPimage series software was written and developed by Dr. Finn Knut Hansen, a Scientist and Professor of Chemistry at the University of Oslo, and is available exclusively from ramé-hart instrument co. Our lineup currently includes three editions as detailed in the matrix below.

DROPimage and Legacy Software

In 2018 DROPimage Standard was replaced by DROPimage Pro and the Surface Tension Tool was added. The first version of DROPimage Pro was v3.1808 and was released on 1-Sep-2018.

In 2002 ramé-hart retired the RHI imaging software and in 2006 support for that product was phased out. We strongly recommend that RHI users upgrade to one of the current editions of DROPimage. Please contact us for upgrade pricing. Here are some advantages to DROPimage over RHI:

  • Real Live Display

  • More Accurate Contact Angle Measurements from Circular Curve Fit Option

  • Improved optimization routines

  • Better Results Output and Presentation

  • Spreadsheet-style Output and Log Files

  • Calculation of Standard Deviations of Surface Energy using the Monte Carlo Simulation

  • Additional Solid/Liquid/Liquid Tool and Single Liquid SE Tool

  • Easy to understand Graphical User Interface

  • Supports Automated Dispensing System (Standard, Pro and Advanced)

  • Supports Automated Tilting Base (Advanced only)

  • Supports Oscillator (Advanced only)

  • Frequent updates and patch fixes are available

  • DROPimage is constantly being improved with new features and support for new options

  • DROPimage is backward compatible with RHI

  • DROPimage supports some legacy cameras and frame grabbers.
