GtestWorks Automated Testing Platform
VectWorks 3.0 Electrical Performance Test Software
Industrial processes and test laboratories require strict, continuous monitoring during the design, verification, and service phases of product development, testing, and manufacturing. The GP Series is Yokogawa Electric's new laboratory recorder, equipped with handles and feet for easy portability and use.
The GP Series uses a multi-touch screen, enhancing intuitiveness and operational intelligence. Users can scroll, pan, and zoom historical data, and even write information by hand on its dust- and water-resistant display. It offers excellent reliability and measurement accuracy. The GP Series is ideal for monitoring long-term physical or electrical trends or performing troubleshooting.

The new custom display function (optional) allows placing graphic images on the screen.

The new touchscreen provides swipe, zoom in/out, and click-and-drag controls for quick navigation of common display mode functions.

Operators can write information directly on the touchscreen with a stylus or finger.

The fully modular I/O design allows you to build a system with the channels you need currently, and expand the device's functions by purchasing and installing additional modules.

The GP10 and GP20 support up to 30 channels and 100 channels of input respectively.

It supports 12 V power supply, so you can also use it in a car.
