Each kind of gem has a typical refractive index due to its chemical composition and crystallization structure. Refractive index is one of most important optical parameter, through the parameters you can judge whether the gem is an anisotropic or isotropic stone. This digital gem refractometer is designed to measure the refractive index of gems with high accuracy ± 0.007 RI. With the full range from 1.400 to 3.000 RI, it can be used to test almost all kinds of gem. You don't need to apply RI fluid, just simply put your sample on the test platform and read the result on the LCD very quickly and conveniently. A gem refractometer is the primary and most powerful tool in gemstone identification. Therefore, it is widely used in jewelry stores, gem workshops, museums & collections, auctions, laboratories and etc SPECIFICATIONS: Measuring range: 1.400 ~ 3.000 RI Accuracy: ± 0.007 RI Working temperature: 10 ~ 28°C (50 ~ 82.4°F) Power source: 1 x 9V battery (included) Item size: approx. 105 x 60 x 35 mm Item weight: approx. 339g FEATURES: Wide measuring range: 1.400 ~ 3.000 RI High accuracy: ± 0.007 RI No refractometer oil needed Read results on LCD Easy and simple to use INCLUDE: 1 x Digital Gem Refractometer (main unit) 2 x Scale Sample 1 x Cleaning Cloth 1 x 9V battery. 1 x Instruction Manual Carrying Pouch Standard Factory Package

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96802

The HI 96802 is a portable, water resistant digital fructose refractometer that employs the measurement of refractive index to determine the percent of fructose in aqueous solutions. The meter helps eliminate the uncertainty associated with mechanical refractometers, and is suitable for field or lab use. Samples are measured after a simple user calibration with deionized or distilled water and within 1.5 seconds the instrument measures the refractive index of the sample and converts it to percent by weight concentration units. The meter features Automatic Temperature Compensation (ATC) between 10 and 40 degrees C/50 – 104 degrees F, and temperature is displayed (in C and F) simultaneously with the measurement on a dual-level LCD display along with icons for low power and other message codes. Auto-shut off feature turns the meter off automatically after three minutes of non use. Range is 0 to 85%; 0 to 80 degrees C (32 to 176 degrees F) + or – 0.2%; 0.3 degrees C (0.5 degrees F) with a resolution of 0.1%; 0.1 degrees C (0.1 degrees F). The device operates on a 9V battery. Dimensions are 19.2 x 10.2 x 6.7 cm, and weighs 420 g. Fructose Refractometers utilize the measurement of the refractive index to determine the percent of fructose in a substance. They are used by researchers, manufacturers, and individuals. Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards. What’s in the Box?
