Manufacturer: Sper Scientific Brand: Sper Scientific Model: 300011C

Salt Refractometer w/ATC 0-100ppt This refractometer features Automatic Temperature Compensation (ATC), which makes manual temperature corrections unnecessary. Double scale in parts per thousand and specific gravity. Measures salt content in sea water, aquariums, breeding ponds, or pickling-brines. While the scale is calibrated for sodium chloride, it can also be used for calcium chloride, barium cobalt, magnesium, cesium, potassium, sodium chloride, cupric sulfate, potassium iodide, citric acid, and acetic acid (vinegar), when tested against a known standard. Place a drop or two of a sample on the prism and read the results. Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision, and optical performance will last forever. All Sper Scientific refractometers come complete with: • Rubber coated hand grip and construction, which insulate the test solution from inaccuracies caused by the user's body heat.• Covered eye piece and bright, clearly defined scale, with large easy-to-read measurements. • All the accessories for immediate use, including calibration tools and solutions, full instructions, transfer pipettes and protective cases. Dimensions: 6½" × 1½" (165 × 38 mm) Weight: 3.0 oz. (86 g) Comes with a Certification of Calibration.

Measuring Range: 1.30 – 1.81 RI Minimum Graduation (RI): 0.01 RI Illumination: Internal illumination with momentary switch Size: 30mm x 70mm x 130mm Scale Division: 0.01 nD Weight: 0.4 kg Ranges of Application: Laboratory, Gemology Filter: Polarizing filter Made of durable heavy metal and scratch proof glass This item is commonly known as Gemstone Refractometer, is the primary and most powerful tool in identifying and authenticating polished precious and semiprecious gemstones and also observing the optical properties and the structure of gemstones. This model is just as good as the expensive models used in gemological institutes, it has a built-in light source and with the aid of the Contact liquid (RI Fluid), which creates an optical contact between the glass and the gemstone, you can measure or test the Refractive Index of faceted stones, its transparency or opacity, and its beauty, durability and scarcity. The refractive index (RI) of a gemstone provides the single most important piece of information to a gemologist seeking to identify an unknown stone. Due to its chemical composition and crystallization structure, each gem has a typical refractive index. In fact, you can also use this tool to measure R.I. for many minerals in crystal form as long as the crystals have a flat and polished face. Through these parameters, you can determine whether the gem is a Single Refraction (Isotropic) or Double Refraction (Anisotropic or Birefringence).

Manufacturer: Grand Index Brand: Grand Index Model: RND025/ATC

This model is specially designed to measure the refractive index in mineral oil or in brix solution. But its measurement range is small, it only can be used to measure the oil or brix solution with high refractive index. Like our other refractometers, it's FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use. Refractive index is very temperature dependent, it is important to use a refractometer with automatic temperature compensation to give you the most accurate measurement in any type of environment temperature. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading. It uses ambient light only and no batteries are needed. Made by experienced craftsmen and are unlikely to break down!

Manufacturer: Grand Index Brand: Grand Index Model: RHB-90ATC Color: Blue Rubber Handle

The RHB-90ATC Brix Refractometer is designed to work with sugar related liquids such as high sugar content, honey, jelly, jam and syrup to help monitor and control sugar concentrations in foods and beverages. IDEAL FOR HIGH SUGAR SAMPLES! Perfect for Beekeepers! You can even use it for Maple Syrup production! Comes in a padded nylon zipper case, with a calibration screwdriver, transfer pipette and users guide. Note to the buyer: This unit is a short barrel unit and does not look like the picture of the blue handled refractometer. It is actually much shorter than that picture indicates. Please see the picture of the Refractometer and the black soft refractometer case to get a better idea of the dimensions (5.5" x 1" x 1").
