Benefits of the MR8870 and MR8880 Mobile Data Recorders
- Capture, record and observe waveforms with a single, portable device.
- Compact and easy to carry.
- Printer option for the MR8880-20 for direct printing of waveforms.
HIOKI MR8870/MR8880 Portable Handheld Memory Recorders
The HIOKI portable/handheld devices MR8870 and MR8880 are rugged memory recorders. They allow to capture, record and observe waveforms oscilloscope-like in mobile applications and in the field.
- Memory recorder MR8870:
- Portable memory recorder with 2 channels analog and 4 channels logic.
- Oscilloscope-like waveform observation and recording of RMS variations.
- Mode for recording instantaneous waveform and RMS fluctuations.
- 1 MS/s, 12 bit A/D resolution, 10 mV to 50 V.
- Record four channels at once by synchronizing two instruments with the bundled PC application.
- Memory recorder MR8880:
- Portable memory recorder with 4 channels analog and 8 channels logic.
- Capture high- to low-voltage signals.
- 1 MS/s, 1 MWord memory (1 channel), 14 bit A/D resolution.
- CAT III 600 V isolation performance; directly measure a 480 V power line.
- 4 completely isolated channels let you simultaneously record data on a 3-phase power line plus have one extra channel.
- -10...+50°C operating temperature range; rugged to withstand mechanical shocks and vibrations (ships standard with side protectors).
- Make settings easily with PRESETS function.
- Printer option available.
- Battery or AC Adapter operation.
- Save values in real time to a CF card.
- Built-in clear TFT LCD.
