1000V Direct Input, Portable 16-channel Memory Recorder for Data Acquisition During Vehicle Testing with Direct CAN Bus Input
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.
Abrupt fluctuations in acceleration can cause unacceptable motion errors in automobiles, transportation equipment and industrial robots. The Hioki MR8857 Memory HiCorder installed with the strain measurement module can greatly assist in helping you measure and analyze these unexpected acceleration fluctuations across 16 channels.
With its multichannel, long-term recording capabilities, the MR8875 is ideally suited for use in development applications such as performance and durability testing. Record sensor output, evaluate sensors and other devices, and even use as a flatbed X-Y recorder.
Install the High-voltage Input Unit MR8905 to easily measure and capture waveforms from the primary- and secondary-side of UPS power supply as well as commercial power supply transformers.
