DISCONTINUED ITEM-Replacement Model: Hioki MR8870-20 Portable Memory Recorder, 2 Channel

Hioki's traditional MEMORY HiCORDER functions are now condensed into a low profile, turn-key device. The compact design includes a beautiful wide-screen QVGA-TFT LCD. Easy to use, with great functionality and performance, you will want to keep this extraordinarily compact MEMORY HiCORDER close to hand.

Note: Test leads are not included. Purchase the leads appropriate for your application separately.

  • Simple, intuitive operation.
    The 8870-20 feels like a hand-held tester, yet takes waveform snapshots.  It has no complicated functions – allowing you to observe waveforms quickly and increasing your work efficiency.  Easily make settings while viewing levels on the Settings screen.  Observe waveforms using only simple memory recorder functions.
  • Compact, easy-to-carry design.
    Volume and weight have both been reduced by 60% from HIOKI’s previously most compact MEMORY HiCORDER, the 8807-01, to just 40% the volume and 55% the weight. Easily pack it in your briefcase to accompany you wherever you go.  Only 176 mm wide, 101 mm high and 41 mm thick.  Weighs only 600 g even with the battery pack installed.
  • Easy connection to a PC.
    Connect to a PC with the supplied USB cable to easily download data that has been automatically saved to a CF card. When the HiCORDER is connected to a PC via USB 2.0, the data is quickly copied from the installed card to the PC: 20,000 waveform screen divisions transfer in about 20 seconds. Use the supplied dedicated application program to display and print waveforms on the PC.  Easy USB 2.0 data transfer.  Dedicated application program for displaying and printing waveforms.
  • Isolated inputs for safe measurements.
    Isolated analog channel inputs provide CAT II overvoltage protection safety for measurements of up to 300 V AC and DC (maximum terminal-to-ground rating). This capability enables safe simultaneous voltage measurements of inverter primary and secondary and stacked battery cells without damaging the instrument.  300 V isolation between measurement terminals and HiCORDER chassis.  300 V isolation between measurement terminals
  • Waveform display and printing, and CSV conversion with PC.
    Either off-line, or via USB 2.0, easily copy data to a PC.  Open a data file with the dedicated Wave Processor (PC application program)for the 8870-20, to import and print waveforms with your own arrow and figure annotations. Of course, screen data can be copied and pasted into common Word and Excel documents to easily create reports.
  • Long-period recording like a pen recorder.
    Record dual-level DC voltage systems as you would with a pen recorder. Use the 10 ms sampling rate to record momentary voltage fluctuations. The internal two-Megaword memory offers about five hours of recording with a 10 ms sampling interval.
  • Dimensions: 176mm (6.93in) W × 101mm (3.98in) H × 41mm (1.61in) D
