  The 178-743-13 SJ-220 series of surface roughness measuring instruments offers excellent portability and ease of use on-site, it now also provides touch screen functionality for intuitive operability. Equipped with a built-in battery, it can perform measurements even in environments where power is not available and can be used approximately 1000 times on a full charge. Cableless and paperless work is also made possible by using the Wireless Unit for Measuring Instrument U-WAVE-TIB. This is a user-friendly device that provides compatibility and versatility to meet the diverse needs of manufacturing sites.

  Measurements can be made on-site, so there is no need to transport large and heavy workpieces. Light and compact, the device is easy to carry and allows for simple one-touch measurement. The device is equipped with a touch screen and a new user interface. You can perform operations like changing the display screen and adjusting the settings with your fingertip. The screen size has been expanded to 2.8 inches, achieving high visibility while maintaining a compact device size to fit in one hand.

  Features:

  • Increased measuring efficiency capable of displaying results and setting conditions via wireless communication when used with option accessory U-WAVE-TIB
  • Built-in 2.8-inch color graphic, back-lit LCD display provides excellent readability, improved visibility and is easy-to-use in dark environments
  • Operation keys are clearly defined on the front of the unit and under the sliding cover
  • Internal memory stores up to 10 measurement conditions and one measured profile
  • An optional memory card can be used to store large quantities of measured profiles and conditions
  • Password protection prevents unintended operations and protects instrument settings
  • The display interface supports 16 interchangeable languages
  • LCD display mode can be freely switched between portrait and landscape as well as left-hand or right –hand direction
