MEMORY HiCORDER MR8847

Description

Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple physical phenomena such as voltage, current, temperature, vibration, weight, acceleration and rotation due to complete isolation between channels and from each channel to the ground.

MR8847-51	(64MW memory, main unit only)
MR8847-52	(256MW memory, main unit only)
MR8847-53	(512MW memory, main unit only)

Note: Main unit MR8847-51/ -52/ -53 cannot operate alone. You must install one or more optional input modules in the unit.
