Portable 2-channel Memory Recorder for Convenient Data Acquisition and Data Transfer
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 8870-20 is a handheld data acquisition (DAQ) recorder built in with 2 analog channels and 2MW of memory, suitable for elevator maintenance, machine, motor and inverter fault analysis, testing and inspections.
Note: Input cords and Battery pack are not included. Purchase the cords appropriate for your application separately. The AC Adapter Z1005 is included as standard.
Compact and easy to carry
• Easy, intuitive operation
• Simple PC connection
