Surface Roughness Tester, Portable

D B Shah & Brothers offers a portable Surface Roughness Tester. The Starrett No. 3800 surface roughness tester is an economical, small, hand-held instrument for measuring surface texture conforming to traceable standards. It can be used on the shop floor in any position including horizontal, vertical and in-between. The easy-to-use No. 3800 operates on numerous surfaces including flat, outer cylinder, outer cone, grooves, and recesses greater than 3-1/4” x 1-1/4” (80 x 30 mm), making it ideal for a wide range of applications like inspection departments, quality control, on the shop floor during machining, during assembly and on site. The No. 3800 determines both roughness parameters Ra and Rz within a wide measuring range plus the piezoelectric pick-up stylus with diamond tip assures very reliable measurement within tolerances that conform to ISO class 3. Roughness parameter Ra is computed to conform to ISO and Rz is computed to conform to DIN. The large, easy-to-read LCD display shows either roughness parameter Ra or Rz at the touch of a button, combined with the selected cut-off length. External calibration of the roughness values is provided by a special CAL button, which makes adjustment very easy. A beep signal informs the user about each individual measurement status when ready. Features: very affordable; handles basic roughness needs; simple to use; convenient, pocket-sized; vivid LCD display; measures Ra or Rz; battery powered or line cord; adjustable cut-off values; diamond tracer tip; and comes with carrying case, charger, and roughness standard and manual.
