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 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. Key Features • 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
