MEMORY HiCORDER MR8875

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. 

Key Features • 1000V input and instantaneous DC or RMS waveform measurement with new Analog Unit MR8905 • Multi-channel logger capable of thermocouple temperature measurement up to 60 ch at 10 msec intervals • Measure multiple channels simultaneously despite handheld portable design • Max. 2 μsec high-speed simultaneous logging for all input channels • Save directly to the SD Card in real time for uninterrupted long-term logging • 16-bit high-resolution measurement of voltage, temperature, distortion and CAN signals • FFT calculation, waveform calculation functions for advanced analysis • Intuitive touch screen for optimal operability • Tough against vibrations and extreme temperatures, with strengthened body ideal for in-vehicle testing and road tests • 3 different power supplie

MEMORY HiCORDER MR8740, MR8741

MEMORY HiCORDER MR8740, MR8741

High-speed, 54- or 16-channel Memory Recorders Provide Advanced Data Acquisition and Rack-Mount Systems Integration


The MR8740 and MR8741 are rack-mountable data acquisition systems that deliver high-speed, multi-channel measurements over maximum of 32+22 channels. The MR8990 DVM unit is a 2-channel input unit for the MR8740/MR8741 for measuring minute fluctuations in output from sensors in automobiles and other equipment and voltage fluctuations in devices such as batteries at high levels of precision and resolution. 

 Key Features • Introducing the DVM Unit MR8990 with high 24-bit resolution! Perform high-speed, high-accuracy measurement without going through a scanner. • Support for multi-channel measurement (MR8740: up to 54 ch; MR8741: up to 16 ch) • Isolated input (between input channels; input-to-chassis isolation: maximum input-to-ground rated voltage of 300 V AC/DC) • High-speed sampling (max. 20 MS/s; with 54-ch type, simultaneous sampling of up to 32 ch) • Ideal for rack-mounting (4U height/within 180 mm; display-less, box-type design) • Display waveforms and make settings on a DVI-D connected monitor and mouse • Remote measurement via LAN using control commands from a PC *Screen monitoring and remote operation available via Internet browser. For faster and more convenient remote operation, we recommend using the Hioki 9333 LAN Communicator.
