Fuzhou Zhongtuo Optoelectronic Co.,Ltd
Gem Tester Refractive index is one of most important optical parameter. Gloss of gem can be estimated by the parameter.The kinds of gem can be precisely determined in accordance with the measured value of refractive index because every kind of gem has its inherent refractive. Besides, index of double refraction can be also measured. Through the parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative.

Particle Size Analyzers
-
Particle systems can be complex, but measuring them doesn’t have to be! Anton Paar offers two different technologies to characterize particles from the nanometer to the millimeter range. The Litesizer series employs light-scattering technology to determine not only particle size, but also zeta potential, transmittance, molecular mass, and the refractive index of nano- and microparticles in liquid dispersions. The PSA series uses laser diffraction technology to measure the size of particles in both liquid dispersions and dry powders in the micro and millimeter range. Side by side they open up a wide range of possibilities for comprehensive particle characterization.

UV Index Measurement
-
The sglux UV-Index sensors measure the UVI with a worldwide unique low measurement uncertainty of less than 5 %. This makes our sensors compliant to the highest measurement precisions class one according the DIN/EN 5031-11, chapter 8. Since 2018 our product UV-Cosine_UVI (ERYCA) is appointed for public authority tasks: The German Federal Office for Radiation Protection (BfS) services 27 measurement points in Germany for public information of the daily UV-Index. Twenty of these points (Andernach, Chieming, Duderstadt, Fichtelberg, Genthin, Giessen-Wettenberg, Schauenburg-Kassel, Langen, Lueneburg, Munchen-Neuherberg, Norderney, Belm/Osnabrueck, Schauinsland, Tholey, Todendorf, Waldhof-Falkenstein, Waldmuenchen, Wurmberg, Zingst and Zirchow) use the sglux ERYCA to obtain the local UV-Index value. In 2017 ARPANSA (Australian Government’s primary authority on radiation protection and nuclear safety) began replacing the existing biometers with SiC photodiode UV sensors (sglux ERYCA) at all network sites. There are currently thirteen measurement sites in Australia that have been upgraded to the new sensors.
