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.
