HIOKI MR8880 Memory HiCorder – Rugged 4-Channel High-Voltage DAQ Recorder

Overview

The HIOKI MR8880 Memory HiCorder is a high-performance data acquisition recorder designed for both field measurement and laboratory applications. It captures high-speed transient phenomena and supports long-term monitoring of voltage, RMS, logic signals, and waveform events. With four analog isolated channels and eight logic channels, it enables simultaneous monitoring of multiple signals such as three-phase power plus control logic. The device achieves high voltage input capability (up to 600 V AC/DC in CAT III) without needing differential probes in many use cases, simplifying setup and enhancing safety. Built rugged for industrial environments, the MR8880 withstands harsh temperatures, vibrations and impact, making it suitable for plant maintenance, power quality analysis, motor start-up diagnostics, inverter or UPS troubleshooting, and more.

Key Features

• High-Voltage Direct Input (CAT III 600 V) for safe measurement of 480 V three-phase power lines without external differential probes.

• Four fully isolated analog channels plus eight logic channels for simultaneous mixed signal analysis.

• High sampling rate up to 1 MS/s on all analog channels to detect fast transients.

• Supports waveform, RMS, DC/AC measurement, and logic signal modes.

• Wide operating temperature range from −10 °C to +50 °C with rugged, shock-resistant housing.

• User-friendly interface with measurement presets for voltage drop, power outage, and waveform capture.
