The Yokogawa GP20 is a portable data acquisition system built around a 12.1″ TFT touchscreen interface for real-time logging and monitoring across industrial and laboratory environments. Dual-model architecture supports 100 input channels (GP20-1) or 450 input channels (GP20-2), expandable via modular I/O architecture. The capacitive touchscreen accepts stylus input and multi-touch gestures—swipe, pinch, and tap—for field operation without external peripherals.
