FuZhou Auyat Optoelectronic Technology 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. The gemological refractometer is characterized by small volume and less weight. It is easy to carry. It is a popular instrument used in jewelry market.

DRK66902W -
Shandong Drick Instruments Co., Ltd.
DRK66902 Abbe refractometer is instrument of measuring refractive rate nD of transparent, translucent liquid or solid and the average dispersion nD-nC (of which measured transparent liquid based). For example, instrument connected with the thermostat can determine refraction rate nD within temperature 10 DEG C for 50. Its use of visual sight, optical dial readings, temperature display, so it’s simple and reliable. The base consists of stainless steel material, and the prism is made up of hard glass, so it is not easy to wear out.

Calibration Oils are one of the most commonly used materials for calibrating refractometers as they have good traceability, particularly to NIST. Having a high temperature co-efficient, Calibration Oils are best used where strict temperature control is adopted either by Peltier or external waterbath between 10 and 75 °C as well as with refractometers operating at ambient by making use of supplied tables or an RI/°C Temperature Calculator as long as the prism temperature is reliably known.
