The Hioki MR8875 is a modular, high-performance memory logger designed for fast, multi-channel signal recording in demanding environments. The unit accommodates four interchangeable input modules and can be configured for up to 60 temperature channels or 16 high-speed analog channels, depending on the module combination. With direct input capability up to 1000 V DC (MR8905) and fully isolated channels, the MR8875 enables safe measurement of both low- and high-voltage signals.
The instrument supports simultaneous sampling on all channels down to 2 µs (500 kS/s), and Hioki’s high-speed SD recording technology allows continuous real-time data saving even at fast sampling rates. This makes the MR8875 suitable for capturing transients, inverter waveforms, breaker operations, motor control signals, or long-duration multi-channel tests.
The MR8875 supports mixed signal acquisition of analog, logic, pulse, temperature, strain, and CAN data, enabling synchronized display and analysis of all parameters. Its 8.4" touchscreen provides intuitive operation and powerful real-time analysis tools including FFT, spectrum display, digital filtering, waveform overlay, and multi-window views.
With its rugged design, JIS D1601 vibration rating, and operating range down to –10 °C, the MR8875 is well suited for automotive field testing and harsh industrial environments. LAN/FTP/Web-server functionality enables remote control and automated data transfer, while flexible power options (AC, DC, or battery pack) make the instrument versatile for both laboratory and on-site use.
