Original Japan HIOKI MR8848 Memory HiCORDER Portable Storage Recorder, 32 Isolated Analog Channels, 20MS/s High Speed Sampling Data Logger

The HIOKI MR8848 Memory HiCORDER is a high-performance portable storage recorder developed by HIOKI Japan, specially designed for harsh on-site transient waveform recording in power, railway, new energy and industrial equipment maintenance.

Adopting shock-resistant rugged portable housing with protective corner bumpers, it passes strict drop and vibration tests for field mobile testing. Support up to 32 isolated analog channels +64 logic channels simultaneous measurement, maximum 20MS/s full-channel synchronous sampling, built-in 512MW large-capacity internal memory and optional 1TB SSD long-term data storage. All channels achieve complete electrical isolation to avoid short-circuit risks between different circuit systems, safely measuring high-voltage power equipment, vehicle electrical systems and industrial automation signals. Equipped with 10.4-inch high-definition display, integrated FFT spectrum analysis, waveform pass/fail judgment, LAN/USB data transmission, and optional U8351 A4 printer unit for on-site hard copy waveform output.
