Counting unit C8855-01

Counting unit The C8855-01 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 C8855-01 has two counter circuits (double counter method) capable of counting input signals with no dead time. Since the C8855-01 is hot-swap compatible (plug and play compatible), it helps you set up measurement environment quickly. You can start measurement on the day the C8855-01 is delivered by the sample software. Click here to view a full product spec sheet PDF.
