The Yokogawa MV1024 is a 24-channel portable paperless recorder for industrial and laboratory data acquisition. It captures thermocouple, RTD, and DC voltage signals with dual sampling modes: 1 second normal mode and 125 ms fast sampling mode. Data logs to internal flash memory (80 MB, 200 MB, or 400 MB) or external CompactFlash and USB storage. The 10.4-inch TFT color LCD (640 × 480 pixels) displays real-time measurements with configurable bar graphs and four viewing orientations. Ethernet connectivity enables remote monitoring via HTTP and FTP, with text and binary file export formats for post-acquisition analysis.
