Yokogawa MV2020 Portable Paperless Recorder, 20 Ch, 1 S (Fast sampling mode: 125 ms)

The Yokogawa MV2020 is a 20-channel portable paperless recorder engineered for multi-signal data acquisition and long-term logging across industrial and laboratory environments. It delivers dual sampling modes - 1 second normal operation and 125 ms fast sampling with 1.67 ms A/D integration - paired with a 10.4-inch TFT color display (640 × 480 dots) for real-time waveform visualization and system configuration. The unit accepts thermocouples (J, K, T, R, S, B, E, N, W, L, U, WRe), RTDs (Pt100, JPt100), and DC voltage inputs (±20 mV to ±50 V) with channel-isolated measurement paths.

Internal 400 MB storage expands via CompactFlash cards or USB media.
