Choosing a ramé-hart instrument
We offer a variety of instruments for every need. In general, the price of the model increases as the model number increases. Models are available from an approximate price range of $5,000 to $25,000. Many accessories are available as modular upgrades, unlocking new capabilities and improving ease of use. Compatible accessories and software upgrades can be purchased and installed later, so there is no need to commit to a feature if you are not sure you will need it.
All our models are offered as fully functional turn-key systems, including the instrument, a PC with software pre-installed and configured, and the parts and tools needed to set up and operate the instrument. Some models include accessories bundled with the instrument for additional savings.
