5. LCD multi screen display, strong human-computer interaction, full touch data input and data switching display.

The screen body of a touch screen is a multi-layer composite film that fits perfectly with the surface of an LCD display. It is made up of a layer of glass or organic glass as the base layer, coated with a transparent conductive layer (ITO film) on the surface, and covered with an outer surface hardened, smooth and scratch resistant plastic layer. Its inner surface is also coated with a transparent conductive layer, and there are many small (less than one thousandth of an inch) transparent isolation points between the two conductive layers to isolate them. As a new computer technology, touch screen is currently an advanced and convenient human-computer interaction input device. With this technology, we only need to lightly touch the symbols or text on the display screen with our fingers to achieve operations, making human-computer interaction more straightforward.

6. Innovative use of new capacitive touch keyboard CTS technology design, with rich tactile and acoustic sensations, simple operation, and beautiful appearance.

7. The test data of the instrument sample can be automatically calculated and processed, and it complies with the GB/T3048.2-2007 standard. If communication software is used, it can also be connected to a microcomputer to achieve computerized management. The internal circuit adopts dual microcomputer processors and a 24 bit high-performance AD converter, with high intelligence, superior performance, high measurement accuracy, good reliability, and easy operation.

8. The instrument adopts full panel calibration operation, without the need to open the instrument for any internal adjustments. User operation is easy to learn and remember.

9. Measurement methods: manual measurement and automatic measurement, optional
