Hioki MR8847A Series MEMORY HiCORDER

MR8847A-Series ฟังก์ชั่นการวัด

Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously 

measure multiple physical phenomena such as voltage, current, temperature, vibration, acceleration and 

rotation due to complete isolation between channels and from each channel to the ground.
