Sugar Refractometer 28 ~ 62% Use this refractometer to test solutions with a higher sugar content, such as fruit juice concentrates, canned fruits containing added sugar, or ketchup as well as for egg yolk. 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) .

Product Overview This dual scale Salinity Refractometer is used to measure, monitor and control the concentration of salt water and brine, especially useful for aquarium and marine applications. Designed with 2 scales, Specific Gravity (D 20/20) and parts per thousand. With just a couple of drops of aquarium water, you know exactly what the salinity is and determines the amount of dissolved salt and dissolved solids. Features: Used to measure the salinity and specific gravity of the water. Sturdy and light weighted Aluminum body. Superior quality rubber grip. High quality and accurate testing result. Can be easily calibrated with a mini-screw driver. Automatic temperature compensation (ATC) Easy to use, convenient to carry. Specifications: Size(approx): 195 x 40mm Measure Range: 0-100%(0-10%) Accuracy: 0.001sg(1%) Salinity Proportion: 1.000-1.070sg Package Includes 1 x Salinity Refractometer 1 x Fabric Cloth 1 x Dropper 1 x Screwdriver 1 x Hard Case 1 x User Manual

Manufacturer: Extech Instruments Brand: Extech Model: RF15

Use these refractometers to take accurate and repeatable measurements of sugar, salt, lubricants, antifreeze, cutting fluids, and more! Simply place 2 or 3 drops of your sample on the prism; the focus adjustment makes the scale easy to read. Automatic temperature compensation ensures accurate readings from 50 to 86°F (10 to 30°C). Includes calibration solution to ensure accurate results

Manufacturer: ABS Import Tools, Inc. Brand: HHIP Model: 8010-0019

HHIP synthetics coolant Tester - refractometer solution measuring range is 0-15 percent . Accurately measures coolant concentration. Optimize coolant use and tool life. Just a few drops needed for Test. Includes instructions.

Manufacturer: Milwaukee Instruments Brand: Milwaukee Model: MA885

The MA885 is optical instrument that is based on the measurement of the refractive index of a solution. The measurement of refractive index is simple and quick and provides the vintner an accepted method for sugar content analysis. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds the instrument measures the refractive index of the grape. This digital refractometer eliminates the uncertainty associated with mechanical refractometers and is easily portable for measurements in the field. The instrument utilizes internationally recognized references for unit conversion and temperature compensation.

It's essential to know the freezing point of Anti-Freeze coolants for vehicular safety. Keeping a suitable concentration of coolant prevents engine trouble and possible radiator corrosion. These refractometers (available with either °F or °C ranges) monitor the freezing points of both ethylene glycol and Propylene glycol; in addition, they indicate battery recharge level. Simple to use and virtually an indispensable instrument for gas stations, service shops, Cab companies, etc., both models feature automatic temperature compensation (ATC); an ideal choice for testing in conditions with large ambient temperature fluctuations. Anti-freeze coolant testing/battery recharge level. Largest display available. Durable, all-metal design.

These SSV and ATC values are then used to calculate settled sludge concentration, indicating the sludge quality. See APHA "Standard Methods for the Examination of Water and Wastewater" 14th Ed. (1975), Method 213, p. 126. Kit includes 2-liter, transparent polycarbonate jar, polycarbonate cover, polypropylene stirring paddle, ten 15 mL polycarbonate conical bottom centrifuge tubes and sample data sheet. Kit components are chemically resistant to sludge samples in range pH 3 to 10. Jar is approximately 130 mm o.d. x 190 mm high and is graduated from 50 to 1000 cc/L in 10 cc/L intervals. Paddle is 121 x 254 x 3 mm thick. Centrifuge tubes are graduated from 0 to 15 mL in 0.1 mL intervals; overall dimensions: 17 mm o.d. x 119 mm long. Tubes withstand forces of up to 6000x gravity. For replacement centrifuge tubes, see Thomas number 2610K11.

Use these economical refractometers to take quick and easy measurements. Refractometers feature adjustable focus and a zero adjustment screw for calibration. Each refractometer is calibrated and adjusted to read at 68°>F (20°>C). Models with automatic temperature compensation (ATC) are ideal for applications where the temperatures of your sample vary. Refractometers are made of corrosion-resistant brass and have rubber-insulated grips. Include hard case, calibration screwdriver, and instructions. Brix Refractometers measure soluble solid concentration of sugars, salts, proteins, and more in foods and liquids - ideal for quality control and R&D applications. Use to measure percent Brix of juices, beverages, and other sugar-based liquids. Durable units provide quick and easy measurements
