Measuring Instruments and Equipment 486 048 710 Portable Surface Roughness Tester Surftest SJ-410 Both skidded and skidless measurement are possible with this series. Equipped with 46 roughness parameters that conform to the latest ISO DIN ANSI and JIS standards. A wide-range high-resolution detector and a drive unit provide superior high-accuracy measurement in its class. Detector Measuring range 800pm Resolution 0.000125pm (at 8pm range) Drive unit Straightness traverse length SJ-411 0.3pm 25mm SJ-412 0.5pm 50mm A skidless detector and a curved surface compensation function provide efficient evaluation of cylinder surface roughness. Ultra-fine steps straightness and waviness can be measured by using the skidless measurement function. The handheld data processing unit and the 5.7-inch color graphic LCD touch-panel provides superior readability and operability. The LCD also includes a backlight for improved visibility in dark environments. The excellent user interface provides intuitive and easy-to-understand operability. Measured data can be output to a PC with optional RS-232C or USB cable. Digital filter function for non-distorted roughness profiles. GO NG judgment function. Auto-calibration function. The display interface supports 16 languages which can be freely switched. Simplified contour analysis function supports the four types of measurement step level change area and coordinate difference. Access to each feature can be password-protected which prevents unintended operations and allows you to protect your settings. The optional attachments for mounting on a column stand significantly increase the operability.
