Portable Memory Recorder for High Voltage Testing and Fully Isolated Data Acquisition Across 4 Channels




Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple quick-changing phenomena due to complete isolation between channels and from each channel to the ground. The MR8880-20 is a data acquisition (DAQ) recorder built in with 4 analog channels that can accept direct input of 600V, enabling measurements of 3-phase systems. MEMORY HiCORDER MR8880

MR8880-20 4 ch

Note: Input cords and Battery Pack are not included. Purchase the cords appropriate for your application separately. Printer Unit MR9000 is optional and sold separately.CEUSB2

Key Features MR8880

• CAT III 600V isolation performance; directly measure a 480V power line

• 4 completely isolated channels let you simultaneously record data on a 3-phase power line plus have one extra channel

• Tough against harsh environments; -10°C to 50°C operating temperature range

• Built to withstand mechanical shocks and vibrations (ships standard with side protectors)

• Make settings easily with PRESETS function

■ Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
