Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple physical phenomena such as voltage, current, temperature, vibration, weight, acceleration and rotation due to complete isolation between channels and from each channel to the ground. More than just a digital oscilloscope, the MR8827 data acquisition (DAQ) recorder accommodates plug-and-play input modules to meet applications such as trial runs after the scheduled maintenance of railway cars to verify for voltage command signals, motor current, car speed, and brake pressure.
- High-Speed Sampling: Up to 20 MS/s with a resolution of 50 nsec on all channels.
- Isolated Input: Complete isolation for each channel, enhancing safety and performance in testing.
- Inverter/UPS Testing: Ideal for evaluating inverters and UPS with capabilities to record control signals and voltage/current.
- Transformer Interruption Tests: Safe connections in high voltage environments due to inter-channel isolation.
- Multichannel Input: Supports a maximum of 16 modules and 64 channel logic signal input when using 2 Logic Units 8973.
- High-Speed Printing: A4-size thermal printer for high-definition output at 50 mm per second for easy waveform checks.
- Data Storage: A/D converted signals can be saved on optional internal SSD, USB memory, or CF card.
- Versatile Applications: Suitable for power, automotive, power electronics, and mechatronics fields, capable of handling various measurement tasks.
