Control Unit CXS-SG04
Description
The Crystal Probe system is specially designed for the Sentinel Lymph Node method (SLN). This German engineered product is easy to use and quick to set up. Main features of the control unit are:
- Compatible with other Crystal handheld probes – this allows the hospital to add on other probes for different applications without purchasing a new control unit.
- NEW Fully automated system check – The new SG04 control unit has a new function button that automatically performs an internal check of the most important parameters and system functions. The self diagnostic process is displayed on the screen.
- Maintenance Free – The Crystal Probe comes with a factory warranty and requires no maintenance other than replacing the internal battery every 5 years.
- NO Calibration Necessary – Due to the solid state technology of the probe and the automated system check of the control unit, calibration is not required.
- Different Nuclide settings – The unit has a default nuclide setting for 99mTechnetium and 8 other optional nuclides to choose from.
- Excellent energy resolution – Compton- and photopeak-signal are adequately separated, improving the energy resolution of the probe and ultimately improving identification of sentinel lymph nodes.
- Battery operated - The device can be operated directly by mains, or using the built-in rechargeable batteries. The charger is included. Operating time: 13 hours at normal load, 10 hours at maximum load. Charging time: 12 hours.
- NEW Larger Display – The new larger illuminating display screen is easy to read and clearly displays all function of the control unit along with the count rate.
- NEW Background Suppression – This feature eliminates a comparatively high radiation background-count-rate in the operation room.
- NEW Three Acoustic Signals – Three different variable acoustic signals give immediate information about the intensity of the gamma radiation.
