High-speed 20MS/s Multi-channel Memory Recorder Provides Simultaneous Data Acquisition During Field Testing with Rugged Portability and Built-in Printer

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. More than just an oscilloscope, the MR8847 Series accommodates plug-and-play input modules to meet applications such as monitoring commercial power supplies, fault analysis of electrical equipment, testing of automotive mechanisms, and general inspection of various industrial facilities.

Key Features

  • Choice of memory capacity from 64-Mega word (-01 model) to 512-Mega word (-03 model)
  • High-speed sampling with waveform judgment function
  • High-speed sampling up to 20MS/s with fully isolated inputs
  • 16 analog + 16 logic channels to 64 logic + 10 analog channels
  • Large, tough handle makes carrying a snap
  • Soil-resistant construction is strong against adverse working environments

Basic specifications

Accuracy guaranteed: 1 year
of channels
[8 analog input modules]: 16 analog channels + 16 logic channels (standard)
[5 analog input modules + 3 logic input modules]: 10 analog channels + 64 logic channels (standard 16 channels + 48 channels in logic input modules)
* For analog modules, channels are insulated vs. each other and vs. unit ground.
For logic modules and integrated standard logic channels, all channels use the unit ground.
