Overview
The HIOKI MR8875 Memory HiCorder is a high-performance, modular multi-channel data acquisition recorder designed for demanding environments and applications. With support for real-time data saving, extremely fast sampling intervals, and versatile signal input options, it bridges the gap between laboratory precision and field robustness. Whether used in automotive testing, industrial machinery monitoring, energy system analysis or research, the MR8875 offers superior fidelity, durability, and flexibility.
Key Features
-
Ultra-fast simultaneous sampling: up to 2 µs per sample across all analog channels for the full suite of installed input modules.
-
High-resolution 16-bit A/D conversion for accurate measurement of voltage, temperature, strain, distortion, etc.
-
Mixable input modules: The MR8875 main unit supports up to four input modules, enabling combinations for analog voltage, temperature, strain, CAN, logic/pulse signals etc.
-
Large onboard memory: 32 MW (≈ 64 MB) distributed across input modules (8 MW per module when modules are installed).
-
Real-time saving to SD card (and USB) ensures uninterrupted long-term recording, even at fastest sampling speeds.
-
Robust environmental performance: operating temperature −10 °C to +50 °C, vibration resistance per JIS D1601 automotive standard; built-in capacitors to maintain writing to storage during power interruption to avoid data loss.
-
Intuitive user interface: 8.4-inch color TFT touch screen, efficient waveform / numerical calculations (FFT, waveform arithmetic), settings for logic/pulse triggers etc.
Applications
The MR8875 is particularly well suited for use in:
| Use-Case | Why MR8875 is Appropriate |
|---|---|
| Automotive & Road Testing | The ruggedness, vibration resistance, ability to record many analog + logic + CAN channels in real time helps in engine / driveline / sensor validation in moving vehicles. |
| Industrial Machinery / Robotics | High channel count & modularity allow simultaneous monitoring of strain, temperature, acceleration, control signals. Detect anomalies, prevent downtime. |
| Energy Systems / Power Electronics | Voltage distortion, temperature drift, transient events can be captured with high fidelity; useful for inverters, battery systems, renewable generation. |
| Research, Test Labs, R&D | For experiments needing precise, mixed-signal data logging, waveform calculation, FFT, long-duration recording. |
| Field Measurement / On-site Diagnostics | Portable form, multiple power supply options (AC, DC, battery), real-time recording, rugged design. |
Technical Specifications
| Specification | Detail |
|---|---|
| Channels | Up to 16 analog channels standard (with 4 × analog input modules). When using certain scanner modules / voltage-temperature modules, up to 60 channels (voltage/temperature) possible. |
| Sampling Interval / Rate | Full-channel simultaneous sampling as fast as 2 µs (all analog channels). For large channel counts, intervals widen (e.g. 50 µs or more) depending on module type. |
| Resolution | 16-bit A/D converter. |
| Input Signal Types | Voltage, Temperature (thermocouples), Strain, CAN bus signals, Logic / Pulse. |
| Voltage Input Range | Depends on module; some modules support direct up to 1000 V DC/AC with RMS measurement (via MR8905 module) and high-voltage capability. For analog modules, lower ranges (mV to volts) per module spec. |
| Memory | 32 MW total (≈64 MB), distributed per module (≈8 MW per module) when modules are installed. |
| Display | 8.4-inch SVGA color TFT, touch panel. |
| Storage Media | SD card (genuine Hioki recommended), USB for external memory / transfer. |
| Dimensional / Physical | Approx 298 mm × 224 mm × 84 mm, weight ~2.4 kg (with input modules & battery) for standard configuration. |
| Power Supply | AC adapter (100-240V AC), internal battery pack Z1003 (~7.2V DC), external DC supply (10-28V DC); charging time, usage time etc per spec. |
| Environmental Conditions | Operating temp: approx −10 °C to +50 °C (varies with power source), humidity specs; vibration resistance per JIS D1601. |
