Refractometers
A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The refractive index of a certain sample varies for nearly all materials for different wavelengths. This dispersion relation is characteristic for every material. Temperature has a very important influence on the refractive index measurement. Therefore, the temperature of the prism & the temperature of the sample have to be controlled with high precision.

Built-in LED Gem Tester
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.

Wavelength Tracker
10717A
The Keysight 10717A Wavelength Tracker tracks changes in the air's index of refraction to optically compensate for environmental changes. It uses one axis of a laser measurement system to report wavelength of light changes, not changes in position. It is used to correct displacement values reported by other measurement axes in the system, hence improving measurement accuracy. It provides a higher degree of accuracy than environmental sensors such as the 10751C and 10751D Air Sensors.

Brix Refractometer, Sugar Concentration & Refractive Index
PA202
Dual-scale digital refractometer with scales for measuring both Brix (to 85) and refractive index (to 1.5000). Brix is a measure of sugar concentration and is used extensively in the agriculture and food and beverage industries. Refractive index is a fundamental physical property of a solution and is related to the speed light travels through it. Both the Brix and refractive index scales can be used to measure a nearly unlimited number of fluids.

Aluminum Film Index Tester
DRK120
Shandong Drick Instruments Co., Ltd.
DRK120 aluminum film thickness tester is new instruments as the development of new packaging material. It is used to test aluminum coating in the barrier film, which is around 35NM thickness. This aluminum coating improves the barrier property a lot, because common gas and aromatic gas couldn’t dissolve in metal. The aluminum coating could protect packing material and avoid light. So thickness test and control of aluminum film is very important, the thickness of aluminum will affect the barrier property of film a lot.

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.
