Product Introduction

Portable Surface Roughness Tester - TIME3100 is a pocket-sized economically priced instrument for measuring surface texture conforming to traceable standards. It can be used on the shop floor in any position, horizontal, vertical or anywhere in between.

The large 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 roughness values is possible by means of a special CAL button, which makes adjustment of this instrument very easy. A beep signal informs the user of each individual measurement status when ready.

The easy to use TIME3100 operates on various surfaces, not only flat but also outer cylinder, outer cone, grooves, and recesses greater than 80 X 30mm. The areas of application are wide spread. This unit is most suitable for inspection departments, quality control, on the shop floor during machining, assembly and on-site.

TIME3100 determines both roughness parameters Ra and Rz within a wide measuring range (See specifications below). The piezo-electric pick-up stylus with diamond tip assures a very reliable measurement within tolerances in conformance with ISO Class 3. Ra parameter is in conformance to ISO while Rz conforms to DIN standards

Industry Application
There is a report analyzes every business who uses the tester, and enumerate the customers especial Time’s customers in order to comprehend the using of the testers in every industries more deeply.
1. Firstly, the mechanical manufacturing industry, mostly the manufacture of metal. The primary function of roughness tester is testing the surface roughness of processing parts especially the pot-ball roughness tester is adept to testing the hard surface. For example the automobile parts manufacturing, mechanical parts manufacturing, etc. the roughness tester is essential in every manufacturing industry engaged in quality of parts surface.
2. Secondly, the industry of manufacture of non-metal. As the development of science and technology, more and more new materials are used in manufacturing techniques, for example, pottery, plastic, polyethylene, etc. now some bearings are made in special pottery, and some pump valves are made in polyethylene. These materials all have firm character, and some of them can be made into parts instead of metal. Their surface roughness also needs testing in manufacture.
3. As the technology and function of the roughness tester being perfected, besides the mechanical processing, surface roughness testing is also used in electric power, communication and electron, so much as stationery, dishware and the surface of one’s teeth.
