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. The MR8875 data acquisition (DAQ) recorder accommodates plug-and-play input modules to meet applications such as onboard vehicle analysis, current consumption testing of portable devices, and measuring the voltage waveforms of superconducting materials and contacts.
Key Features
