High Precision Portable Surface Roughness Tester/Surface Roughness Gauge/Surface Roughometer

Product Description

High Precision Portable Surface Roughness Tester

Introduction:

The LR310 Surface Roughness Tester precisely measures surface roughness on diverse machined parts. It handles various surfaces, including flat planes, outer cones, cylinders, curves, pinholes, grooves, recesses, and axles. Suitable for both metal and non-metal workpieces, it excels in measuring large/heavy parts, assembly lines, and on-site inspections. Ideal for machining, manufacturing, quality control, and inspection departments. As a non-destructive testing instrument, it prevents workpiece damage.

Automatic Metal Detector
Test principle: Thin samples are irradiated by high-intensity short-time energy pulses. The front side of the sample absorbs the pulse energy to increase the back temperature. The back temperature change is recorded. The time required for the back temperature of the sample to rise to half of the maximum value after receiving the light pulse irradiation (also called the half-heating time) is used to quickly calculate its thermal diffusivity  and thermal conductivity l using a computer through a special mathematical model. Our company's transient laser method thermal conductivity tester is suitable for testing high thermal conductivity materials such as metals, graphite, graphene, silicon carbide, etc. It has the advantages of fast measurement speed and accurate measurement results. It has a high cost-effectiveness and meets the production, quality inspection, and research and development needs of related industries.
