MEMORY HiCORDER MR8740, MR8741
High-speed, 54- or 16-channel Memory Recorders Provide Advanced Data Acquisition and Rack-Mount Systems Integration
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 54- and 16-channel MR8740 and MR8741 are integratable data acquisition (DAQ) systems suited for the performance testing of electric vehicle inverters, motors, and batteries.
• MR8740 (54-ch model, 864 MW memory, main unit only)
• MR8741 (16-ch model, 256 MW memory, main unit only)
* Main unit MR8740/8741 requires input units and other dedicated options. Input cords not included. For more information about input cords and other common options, refer to the detailed catalog.
■ Basic specifications (accuracy guaranteed for 1 year)
