Retrieved from Dr. Hanneman's vault !!! - the famous Diamond Eye Reflectivity Meter. Dating to the 1970's, when the simulant known as Cubic Zirconia was introduced, this was among the the original "Diamond Testers" before thermal conductivity probes came on the market. But the Diamond Eye still has relevance and purpose today, re-configured by Dr. Hanneman as a Relative Reflectivity Meter, using the Auxilliary Scale (see photo), along with his customized testing method. Just calibrate the meter with a reference gem of your choosing (Spinel, in this example), where the needle on the meter points to the bold, vertical hash line at the center of the scale. Now measure an unknown gem, and note the relative needle position. If it points to the left of the Spinel reference mark, then your unknown gem has a reflectivity value (and refractive index) less than Spinel. Or, if the needle points higher up the scale than the Spinel reference position, then your gem has a greater reflective and refractive index value than ...

Manufacturer: MISCO Refractometer Brand: MISCO Refractometer Color: Black

With scales for Honey Moisture, Honey Percent Solids, Honey Specific Gravity, and Honey Density, the MISCO BKPR-4 Digital Honey Refractometer is ready for use by government honey inspectors, professional beekeepers, honey producers, honey mixers, honey brokers, or anyone requiring the absolute most accurate, repeatable honey measurements. The magic behind the precision of the BKPR-4 Digital Honey Refractometer is a result of the Palm Abbe OPTICAL-ENGINE®. This Optical-Engine combines high-precision optics with a 1,024 element linear detector array, more than seven times the elements of the leading competitor. Since honey is comprised of a mixture of mostly fructose, glucose, and water, readings on the MISCO Honey Refractometer are automatically temperature compensated using a special compensation specific to honey. This differs from other refractometers which use "sucrose" temperature compensation, instead of honey compensation. Refractometers using sucrose compensation will have a slight error at 25Â...

Push-button rotation switches adjust the left and right visual fields to an equal brightness, which makes it quick and easy to take measurements. Distilled water is used to zero the Polax 2L; a zero indicator lets the user know the unit is calibrated. To take a measurement, simply fill the sample tube with the sample solution and set the tube on the sample stage. When viewed through the ocular lens, the left and right visual fields will have different brightness levels. Adjust the rotation switches until the fields are of equal brightness. At this point, the correct reading is shown on the digital display. The polarized light source used is a LED with a filter for 589 nm. Two sample tubes are included: 100 mm and 200 mm. The 200 mm tube permits higher accuracy when used with transparent liquids, while the 100 mm tube should be used with cloudy samples containing impurities. The tubes also contain a bubble trap which prevents errors caused by air bubbles in the sample. Also included is a glass thermometer (0-5...

Manufacturer: Magnum Media Brand: MAGNUM_MEDIA

The choice for Winemakers, but beer makers can use this as well! The RHW-25/Brix-40ATC Portable Refractometer Product Specs: * 0-25% Potential Alcohol Scale (NOT Finished Alcohol! Alcohol skews ANY refractometer!) * 0-40% Brix Scale * Accuracy: +/- 0.5% Al & +/- 0.20% Brix * Divisions: 0.5% Al & 0.20% Brix * Sturdy design, made of Aluminum. Included are: a pipette for dropping test fluids onto the prism, a mini screwdriver for scale calibration, and a Users Guide. This Unit is better that the 0-32% Brix Models! This unit can also measure other products as well! The 0-40% Brix Range lends itself to many other uses too! This unit has an extra large Brix Scale so you fully test wine grapes, Beer Mash and more! This unit is tailored to those professionals (and home brewers) working in the Wine, Beer and Liqueur Industries. The Potential Alcohol scale gives you a "ballpark" number of what your finished alcohol will be after fermentation. Excellent unit to double benchmark for quality! FYI - NO RE...

This refractometer provides higher measurement that reaches up to 0-18% brix (measuring range), 0.20 brix divisions ,accuracy of ±0.15% and ATC of 10°C~30°C or 50°F~86°F. Specially designed for people involved with food harvesting, processing and packaging. To measure or test the concentration or refractive index of liquids and work with sugar-related liquids such fruits and vegetables juices and sugar in food and beverages to ensure product quality, Reamsian Bodily Fluids (per the Reams Biological Theory of Ionization), and Maple Sap or for synthetic or semi-synthetic coolants (for machining and grinding coolants, please consult the Technical Data Sheet for appropriate concentration of fluid), monitor the specific percentage of sugar concentration in food and beverages, and can easily check the ripeness of fruits in the field. And because it uses ambient light only, no batteries or power source is necessary to view the chart clearly. It's fully equipped with ATC that automatically adjust itsel...
