Yokogawa MV112-1-2-1D

The Yokogawa MV112-1-2-1D is a 12-channel portable data acquisition unit within the MV100 MobileCorder series, engineered for real-time measurement and logging of mixed sensor inputs. The system accepts DC voltages, thermocouples, RTDs, and digital inputs on a single platform, with data displayed on a 5.5-inch wide-viewing-angle color LCD. Modular architecture enables flexible channel configuration for diverse industrial and laboratory applications requiring synchronized multi-parameter acquisition.
