LS175 45/0 Colorimeter with 20mm Aperture

LS108 Spectrum Transmission Meter Model: LS108 Manufacturer: Linshang - China LS108 spectrum transmission meter is a professional optical transmittance tester for measuring the spectacle lenses, coating materials, organic materials, anti-blue light materials and other materials. The meter combines three measuring light paths into one. Users can select to measure the transmission rate or rejection rate. Four display interfaces can be switched. The LS108 spectrum transmission meter uses a 395nm purple light source, a 430nm blue light source and a visible light source to illuminate the transparent material during test. The sensor detects incident light intensity of the three light sources and the light intensity after passing through the transparent material. The ratio of transmitted light intensity to incident light intensity is transmittance, displayed as a percentage.

LS177 Large Aperture Spectrocolorimeter Model: LS177 Manufacturer: Linshang - China Powder and masterbatches color comparison 50mm large test aperture Provide professional reflectance curves Good repeatability, △E*ab≤0.03 WI-R457,WI-Hunter,YI-98 and other parameters measurement

LS251D Leeb Hardness Tester Model: LS251D Linshang - China The ability of a material to locally resist hard objects pressing into its surface is called hardness, which is an index to measure the softness and hardness of a material. Based on the principle of Leeb hardness measurement principle, LS251D Leeb Hardness Tester can detect the hardness of a variety of metal materials. It adopts advanced digital probe technology, and the digital signal processing is completed directly on the probe which means that the probe is not easy to be disturbed and provides excellent accuracy. The orientation sensors inside the probe will compensate the measurement errors in different impact directions automatically to ensure the accurate data. Providing a variety of hardness scales , such as Leeb scale (HL), Vickers scale (HV), Brinell scale (HB), Shore scale (HS), Rockwell scale (HRA/HRB/HRC), and they can make a mutual conversion to avoid cumbersome manual calculation. Besides the hardness, the instrument can measure the strength of the materials. The practical value of using LS251D Leeb Hardness Tester for hardness testing lies in its incomparable portable characteristics that bring users a perfect experience.
