Hioki Memory Hicorder MR8847 Series


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.

• MR8847-01 (64MW memory, main unit only)
• MR8847-02 (256MW memory, main unit only)
• MR8847-03 (512MW memory, main unit only)
* Main unit MR8847-01/ -02/ -03 cannot operate alone. You must install one or more optional input modules in the unit.

■ Basic specifications (Accuracy guaranteed for 1 year)

Number 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.
