Yokogawa MV1012 Portable Paperless Recorder, 12 Ch, 1 S (Fast sampling mode: 125 ms

The Yokogawa MV1012 is a 12-channel portable paperless recorder designed for multi-parameter data acquisition in laboratory, field, and industrial environments. It captures temperature, voltage, and contact signals with selectable sampling rates - 1 second per channel in normal mode or 125 ms per channel in fast sampling mode - and stores data to internal Flash memory or external Compact Flash and USB media.

Technical Specifications

• Channels: 12 input channels


• Sampling Rate: 1 second per channel (normal mode); 125 ms per channel (fast sampling mode)


• Internal Memory: 80 MB, 200 MB, or 400 MB Flash memory options


• Storage Duration: Approximately 75 days (200 MB) or 148 days (400 MB) continuous recording at 12 channels, 1-second intervals


• External Storage: Compact Flash (up to 1 GB) and USB memory support


• Display: 5.5-inch TFT color LCD, 320 × 240 dots


• Input Types: Thermocouples (R, S, B, K, E, J, T, N, W, L, U); RTD (Pt100, JPt100, Pt50, Cu10, Cu25); DC voltage (±50 V); contact input (TTL level, >2.4 V ON, <2.4 V OFF)


• Measurement Accuracy: Type K thermocouple example: ±(0.2% of reading + 4°C) or ±10°C at 0 to 100°C


• A/D Integration Time: 16.7 ms or 1.67 ms depending on mode


• Alarms: Up to 4 per channel; high/low limit, difference high/low, rate-of-change high/low


• Event Actions: Up to 40 configurable actions


• Power Supply: 90–132 VAC or 180–264 VAC (AC adapter); 12 VDC or 24 VDC (DC supply)

Key Features

• Dual-mode sampling accommodates both standard monitoring and high-speed transient capture


• Multiple data-saving modes: Free (continuous), Trigger (with pre-trigger), Manual, Auto-save, and Snapshot


• Binary or text format export to external media; internal storage uses binary format


• Comprehensive alarm and event-action engine for condition monitoring and automated response

Typical Applications Temperature profiling, process validation, equipment diagnostics, thermal transient analysis, multi-point data logging across manufacturing and test environments.

Compatibility & Integration Accepts industry-standard thermocouple and RTD sensors. Exports via Compact Flash card or USB memory for post-acquisition analysis.
