The Yokogawa MV2008 is an 8-channel portable paperless recorder designed for reliable data logging and monitoring across laboratory and field environments. This compact instrument acquires data from thermocouples, RTDs, DC voltage, contact inputs, and specialty signal types including strain and pulse measurements. The MV2008 delivers sampling rates from 125 ms (normal mode) down to 25 ms (fast sampling mode), with flexible trigger capabilities—alarm, external contact, time-based, and calculated data—plus pre-trigger functionality for efficient capture. Data stores to 400 MB internal flash memory with expansion via Compact Flash cards and USB drives.
