Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple physical phenomena such as voltage, current, temperature, vibration, acceleration and rotation due to complete isolation between channels and from each channel to the ground.
The MR8847A delivers 20MS/s sampling, 16 isolated channels, and max. 1000V direct input, all housed in a tough and field-ready body to properly respond to the most challenging work sites from transformer substations to railway maintenance yards to paper and steel mills.
Key Features: Hioki MR8847A MEMORY HiCORDER
- Supports a wide variety of measurements with a total of 13 plug-in modules
