Description
The Hioki MR8741 Memory HiCorder is a high-speed, rack-mounted, multi-channel waveform recorder and generator built for demanding industrial and production environments. With sampling speeds up to 20 MS/s, fully isolated 16 analog channels, and support for logic channels, the MR8741 delivers safe, synchronized, and precision data acquisition across various applications including automotive, power electronics, and factory automation.
Equipped with the DVM Unit MR8990, the MR8741 provides 24-bit resolution and exceptional voltage measurement accuracy—without requiring a scanner—making it ideal for fast, high-resolution multi-channel measurements.
Its space-saving 4U box-type design is optimized for rack mounting. You can operate it via a connected DVI-D monitor and mouse, or remotely via LAN using command control or browser-based interfaces. For even more responsive remote control, the Hioki LAN Communicator 9333 is recommended.
Whether it’s recording real-time analog and logic signals or generating test waveforms, the MR8741 is a single-instrument solution engineered to streamline your testing environment with precision, flexibility, and ease.
