The SJ-220 series of surface roughness measuring instruments offers excellent portability and easier use with touch screen functionality for more intuitive operability. It is equipped with a built-in battery that can be used approximately 1,000 times on a full charge, enabling operators to perform measurements in environments where power is not available. The SJ-220 features a larger color touch screen than the SJ-210, with its screen size expanded to 2.8 inches for better visibility while maintaining a compact size to fit in one hand. Its new user interface is more intuitive with easier operations such as changing the display screen and adjusting the settings with your fingertip. The SJ-220 also includes functions such as disabling the touch screen for better security and setting shortcuts using the Home key for your most-used functions. Included in this package...
