Counting Unit C8855
The C8855 is a counting unit with a USB interface and can be used as a photon
counter when combined with a photon counting head, etc.
The counter of the C8855 has two counter circuits (double counter method) capable
of counting input signals with no dead time. The USB interface easily connects to a
notebook PC allowing measurement in an even wider application field. When used
with a photon counting head, the C8855 supplies power (+5 V / 200 mA) necessary to
operate the photon counting head.
Since the C8855 is hot-swap compatible (plug and play compatible), it helps you set
up measurement environment quickly. You can start measurement on the day the
C8855 is delivered by using the sample software that comes with the C8855.
The C8855 cannot be used in simultaneous dual- channel measurements or long-time
measurements with a fast time resolution. In such applications, use the M8784 counting board also available from Hamamatsu.
• Time-resolved measurement (minimum resolution: 50 µs) for monitoring chemiluminescence and biological
• Quick measurement setups (hot-swap compatible)
• Applicable to various measurement methods
Supplied: CD-ROM (containing instruction manual, device driver, DLL, sample software, etc.) USB cable, AC adapter, AC cable, power output connector
*: Sample software is configured from Lab VIEW™ of National Instruments, Inc.

When software such as a device driver is installed into your PC beforehand, you can start measurement by just connecting the
USB cable, without restarting the PC.
The C8855 is fully controlled by DLL (dynamic link library) functions that come with the C8855.
All information on these DLL functions is available to support software programming that handles various types of user
measurement applications.
: Conforms to the EMC directive (89/336/EEC) and the low voltage directive (73/23/EEC) of the European Union.
