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

Brix refractometers show the concentration of the soluble solids content (total solids) of a water-based solution. The soluble solids content is the total of all the solids dissolved in the water such as sugar, salts, proteins, and acids. The measurement reading value is the sum total. These refractometers are an excellent choice for testing fruit juices, beverages, jams, jellies and syrups. Also very useful for wineries, breweries, fruit harvesting, and food canning/packaging. An ideal choice for testing in conditions with large ambient temperature fluctuations. Automatic temperature compensation (ATC) from 50 to 86°F (10 to 30°C).

Includes Carry Case (1 ea.) Plastic Transfer Pipet (1 ea.) Instruction Manual (1 ea.) Features Largest Sharpest Display Scale Available Exclusive Zero-Ring Requires No Calibration Tools Durable, All-Metal Design Easy to Use. Operation consists of placing 1 or 2 drops of sample on the prism, closing the daylight plate over the sample, then looking through the focusable, cushioned-rubber eyepiece for the readings. Accurate. Featuring the largest, easiest-to-read scale available with clear, sharp figures, screen shading, and incredible contrast. These features significantly enhance overall accuracy even when several different operators use the instrument. All units feature rubber grips on the body, which block the transmission of hand heat to reduce temperature errors. Compact Portable. The small size of the X-Series models allows them to be used anywhere the field, plant, or lab. Tool-Free Calibration. The VEE GEE exclusive Zero-Ring eliminates the hassle of using a separate tool for calibration. Simply place a few drops of distilled water or liquid standard (R.I. oil or prepared sucrose solution) on the prism, turn the built-in Zero-Ring until the shadow line is at the correct value of the liquid, and secure the set screw that's it Durable. The X-Series models feature rugged construction to provide years of reliable use. The prism is mounted in an all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. Also feature non-roll stands to ensure that once the units are placed on a table or bench top, they won't be prone to roll off the surface. Wide Selection of Scales Ranges. Choose from Brix, Salinity, Refractive Index (nD), and Coolant (freezing points of Ethylene Propylene Glycol, Battery Charge Level). Automatic Te

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 (0-50°C).

Description: The model RHA-503ATC is specially for Glycol analysis / testing: It offers a convenient, fast and accurate way for testing / analyzing the glycol concentration of engine coolants and other anti-freeze solutions. Also, it has additional scales for battery fluids' gravity and for measuring the freezing point of windshield cleaning fluid. The Antifreeze/ Battery/cleaning fluids Refractometer is designed for testing for concentration of the battery fluids, antifreeze liquid and cleaning fluids. With the indication of the percentage you may know at which temperature the fluid will be frozen for both propylene glycol and ethylene glycol. It can also be used for checking the strength of electrolyte solution batteries. Monoethylene glycol and mono propylene glycol are used extensively as antifreeze in closed cooling systems. Dose concentrations vary dependant upon the level of antifreeze protection required (oC). Refrigeration units and engine cooling systems use glycol in concentrations up to 60% v/v to maintain coolant fluidity at low temperatures. It's FULLY EQUIPPED with ATC(Automatic Temperature Compensation) that automatically adjust itself to correct temperature discrepancies during use. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading.

Sugar Refractometer 0 ~ 32% w/ATC This refractometer features Automatic Temperature Compensation (ATC), which makes manual temperature corrections unnecessary. The most popular refractometer range due to its usefulness in a wide variety of quality control applications for the sugar content of fruit, fruit juices, wine, milk, soft drinks and yeast cultures solutions. Also used for industrial cutting, lubricating, soluble tempering oils and emulsification solutions. 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.
