The surface roughness tester is a compact portable device for shop floor use and mobile measurement. Its operation is straightforward, and it performs well overall. This tester is applicable to the manufacturing floor and can be used to gauge the surface roughness of various parts that have undergone machine processing.

NextGen’s NG-SR400T Surface Roughness Tester has the following optional sensors:

• NG-SR55 – Extension rod. Used to extend length of sensor when testing deep hole (55mm)
• NG-SR90 – Right angle measuring mechanism.
• NG-SR100 – Standard sensor, plane & shaft & inner surface of hole>6mm, depth <22mm
• NG-SR120 – Small hole sensor, cylindrical& plane &inner surface of hole>2 mm, depth <9mm
• NG-SR110 – Sensor for curved surface & plane, cylindrical, curvature radius>3 mm
• NG-SR131 – Sensor for deep groove, cylindrical & plane & groove width>3 mm, depth<10mm
• NR-S520 – Metal Working Platform Designed for elevating, and stability during the testing procedure
• NG-SR620 – Marble Substrate Working Platform, elevating, V groove, high accuracy to test tiny work piece.
• NR-SRB-GEN – Roughness comparison block High quality comparison block of surface roughness with anti-rust treatment. 30 comparison block/set
