Product Details: surface roughness measuring equipment SJ-201 Description: 
 Large LCD display can provide error-free reading? For portable energy supply provided by two well-known species of all sorts of compliance with ISO, DIN, ANSI and JIS standard roughness evaluation parameters drive / detection devices and display devices can be separated from the measurement in the completion of the limited space measurement data via a RS-233C cable with the roughness of the output by an external standard PC boards, transport boxes, GO / NG Judgement filtering function can be obtained by digital distribution of all real roughness of the surface of auto-calibration function SJ-201 Roughness Tester Features: ■ corresponds to the diameter of States to indicate the machine specifications. ■ Large LCD screen window, clear and easy to read. ■ Using the touch panel (with fouling), ease of operation. ■ Data can be stored on the memory card (sold separately). ■ any length setting function. Just press the PRINT button ■ Built-in printer to print out by the measurement results (can choose different ways of printing). ■ Built-in rechargeable battery, portable body is also set to be received by detector. ■ has a wealth of parameters: automatic calibration function, statistical processing, to determine whether the functional cooperation, customer self-editing function of the design function to determine
