Germany HTechMT SP100 Pointer Roughness Gauge

SP100

Roughness Gauge

Specially measure sand blasting or shot blasting surface roughness, can also be used to test the depth of the pit caused by corrosion, accuracy 1 μm, execution standards: ASTM D4417 and SANS 5772

Introduction

Surface roughness meters are used to accurately measure the peak to surface roughness of sandblasted or shot blasted surfaces. The average value of a series of measurements is the surface roughness of the measured surface. Allows comparison of surfaces during spraying. In addition to roughness assessment of sandblasted or shot blasted surfaces, the instrument can also be used to measure the depth of pits caused by corrosion. The instrument has an accuracy of up to 1um. Implementation standards: ASTM D4417 and SANS 5772

Instructions

1. Place the surface roughness meter on the glass piece, press the base firmly, and adjust the reading of the meter to 0.

2. When reading data, place the instrument firmly on the surface of the object being measured. When measuring, do not drag the instrument on the surface under test. Doing so will cause the spring-supported measuring points to wear out, leading to data errors.

3. According to the description or opinions reached by the relevant parties, select enough points in each area that can represent the roughness of the measured surface for testing, and then select at least 10 points in the tested area for testing, and the average of the test values ​​​​of the 10 points The value is the surface roughness of that area.
