Yokogawa MV2048 Portable Paperless Recorder, 48 Ch, 1 S (Fast sampling mode: 125 ms)

The Yokogawa MV2048 is a 48-channel portable paperless recorder engineered for multi-parameter data acquisition across industrial and laboratory environments. It delivers simultaneous sampling at 125 ms intervals in fast mode, with configurable standard sampling from 1 s to 10 h/div. The instrument accepts universal inputs

DC voltage, thermocouple, RTD, and digital signals - with channel isolation on DC and thermocouple inputs.

Data logs to 200 MB internal flash memory or external CompactFlash and USB media in binary or text formats.
