The O2C is available in 12 variations. The variations
differ in number of connected probes, the different number of channels,
measuring depths of a probe and the parameters which can be recorded per
channel.
A measurement channel is usually equipped both with a laser-Doppler-measurement-unit
and with a tissue-spectrometer-unit with white light source (O2C). The
following table shows all types with different available extensions.
| Parameter | Devices Types | ||
| O2C | O2C-OF | O2C-ATS | |
| Velocity and Flow | +1 | +1 | -2 |
| SO2 and rHb | +1 | -2 | +1 |
| Superficial I - 1 Probe | This device is equipped for the connection of one probe which works in one measurement depth. | ||
| Superficial II - 2 Probes | This device is equipped for the connection of two probes which work in one measurement depth at different places. (Application e.g. for right-left-comparison or control and experimental measurement place) | ||
| Depthselective I - 1 Probe | This device version has a connection for one probe which enables a place- and time-synchronised recording of values in two measurement depths on the surface and in deeper tissues. | ||
| Depthselective II - 2 Probes | Here there are two connections for two probes which enable a place- and time-synchronised recording of values in two measurement depths on the surface and in the deeper tissue of two different places. (Application e.g. for right-left-comparison or control and experimental measurement place) | ||
