Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96801

The Hanna Instruments HI 96801 is a portable, waterproof meter that measures the refractive index of samples in order to display sugar content in a substance, displaying results within seconds. To take a reading, the sample well must be calibrated with distilled or deionized water, followed by a few drops of the sample liquid. A dual-level LCD screen displays the measurement and temperature within several seconds. The meter converts the refractive index of the sample to sucrose concentration in units of percent by weight (%Brix, also referred to as degrees Brix). The single 9V battery-operated device has Automatic Temperature Compensation (ATC), and automatically powers off after three minutes of non-use. The meter has a range of 0 to 85%Brix/0 to 80 degrees C (32 to 176 degrees F) with accuracy + or - 0.2 %Brix / + or - 0.3 degrees C (+ or -0.5 degrees F) and a resolution of 0.1 %Brix/0.1 degrees C (0.1 degrees F). The meter uses the methodology from the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Its dimensions are 19.2(W) x 10.2(D) x 6.7 (H) cm, and it weighs 420 g. Refractometers measure refractive index, which is the optical characteristic of a substance and the number of dissolved particles in it. Refractive index is the ratio of the speed of light in empty space to the speed of light in the substance. Refractometers are often used in the beverage making process to determine sugar content. Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions.

Manufacturer: Atago Brand: Atago Model: ATA-2691

The Atago 2691 Master-Milk is a handheld, portable, refractometer that measures the percentage of milk concentration (0.0 to 23.0%) with a refractive index measurement, has automatic temperature compensation (ATC), and is housed in an Ingress-Protection (IP)-65 rated metal body. A milk refractometer measures milk concentration in a refractive index of a milk sample, converts it to concentration in units of percent by weight, and displays the results. Handheld refractometers are commonly used in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, and ecological industries, and for water-testing applications. This refractometer is housed in a durable, die-cast, Ingress-Protection (IP)-65 rated, aluminum metal body for heat and organic solvent resistance, and protection against dust and water jets. The 2691 Master-Milk features automatic temperature compensation (ATC) for immediate, accurate calibration readings, regardless of ambient temperature. Calibration can be controlled and adjusted with an exposed calibration screw and an included specialized screwdriver, although other items can be used to unscrew the unit. However, the unit retains its water-resistance. Ambient light illuminates the scale, and no additional power source is required. The outer shell grip is ridged for gripping, and easy to clean, which reduces the possibility of food and sample entrapment, avoiding contamination and bacterial growth. The analog salinity scale features a bright, high-contrast display for clear visibility of the boundary and memory lines intersection. Samples are viewed through a monocular, focusable, cushioned eyepiece. The unit includes a protective plastic storage case with a foam cut-out insert to cushion the instrument. Specifications Measurement scale range 0.0 to 23.0% milk concentration (ATC) Minimum detection scale 0.5% milk content Measurement Accuracy + or - 0.5% (10 to 30 degrees C) Repeatability + or - 0.25% Standards met IP-65 (excep...

Manufacturer: MISCO Refractometer Brand: MISCO Refractometer Color: Blue

The MISCO DEF-201 refractometer is the ideal method for testing and monitoring the concentration of urea-based Diesel Exhaust Fluid (DEF or AdBlue) required by diesel engines equipped with Selective Catalytic Reduction (SCR) technology. This refractometer has a single scale for DEF concentration. Diesel Exhaust Fluid (DEF) is already a reality for trucks, buses, and highway vehicles powered by diesel engines. In 2014, new Tier IV guidelines go into effect for off-road equipment as well. These regulations will affect excavators, bulldozers, skid steers and other commercial construction equipment. Also affected are farm tractors and agricultural equipment, heavy forklifts, and airport ground service equipment. Even diesel powered stationary equipment such as generators, pumps, and compressors will be required to meet emission requirements. To comply with EPA regulations, engine manufacturers are using Selective Catalytic Reduction technology which requires a very precise concentration of liquid urea (DEF) in order to operate properly. MISCO refractometers meet or exceed the requirements of ASTM D7821 - 12, Standard Test Method for Field Test Determination of Urea Concentration in Diesel Exhaust Fluid (DEF). Even concentration variations of as little as +/-0.8% will prevent a DEF fluid from meeting the specifications mandated by International Standards Organization (ISO). DEF dilution or contamination can impact system performance and maintenance costs. The biggest contamination threat is water dilution but without the proper tools it is nearly impossible to know if a DEF supply has been diluted. Scale Fluid: Urea (NH2)2C0; Unit of Measure: % Weight/Weight; Range: 0 to 51; Resolution: 0.1; Precision: +/-0.1 INCLUDES: MISCO Palm Abbe Refractometer, Protective Rubber Armor Jacket, Instruction Manual An optional Rugged Case is available from our Amazon store.

Manufacturer: MISCO Refractometer Brand: MISCO Refractometer Model: PA202 Color: Blue

Dual-scale digital refractometer with scales for measuring both Brix (to 85) and refractive index (to 1.500). Both the Brix and refractive index scales can be used to measure a nearly unlimited number of fluids. The Palm Abbe PA202 is a dual scale digital refractometer with scales for measuring both Brix and Refractive index. The PA202 measures Brix from 0 to 85 Brix, which is considerably higher than the Brix scale in the PA201. Brix is a measure of sugar concentration but is also used for measuring the concentration of many other fluids such as metalworking fluids, industrial lubricants, and other industrial chemicals. Also included in the PA202 refractometer, is a second scale for measuring the refractive index of a fluid. Refractive index is a physical property of a fluid that is related to the speed at which light passes through it. The denser the solution, the slower light passes through it and the higher the refractive index. The Palm Abbe refractometer is fast, convenient, and easy to use. Simply place a drop or two of fluid in the stainless steel well and press a button. The custom-designed microprocessor delivers a nearly instantaneous readout in degrees Brix. Nonlinear temperature compensation is automatic and insures that fluids read between 0 and 50 °C (+32 to 122 °F) are measured accurately. Calibration is automatic and does not require the use of special calibration solutions, or tools. The Palm Abbe refractometer automatically calibrates itself to water and is ready to use in seconds. No screws to turn and nothing to adjust.

Manufacturer: Happy Hours®

This refractometer measures the density of unfermented brewer's wort or wine must, providing quick and accurate readings with only a few drops of sample fluid. This handheld version is packed with features to make it perfect for both brewers and winemakers. The refractometer provides measurements in both °Brix and Specific Gravity, and automatically adjusts for temperature of the sample. The viewing lens also has an adjustable focus to eliminate the need to wear prescription eye glasses to see the display clearly. It is durable, lightweight, and comes with a protective, hard-shell case. It also comes with a plastic pipette to collect the liquid samples, a screwdriver to adjust the calibration screw and a micro-fiber cloth to keep the prism glass clean. Since alcohol affects the refractive properties of liquids, the refractometer can only be used on unfermented wort or must (or other sugar solutions). Final gravity (density after fermentation) must be calculated, rather than measured directly.
