HIOKI 8953-10 HIGH RESOLUTION UNIT Voltage (high
resolution) input Amplifier
This unit is one input channel. Simply slot the 8953-10 into the Digital
Oscillo Series MEMORY HiCORDER 8855 for use. To measure high voltages, this
into comes equipped with a power terminal for the DIFFERNTIAL PROBE 9322. It
can alse be connected directly to each channel.
