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).

Hydrometers are manufactured to the exacting specifications provided by NIST, ASTM/API and IRS and are calibrated against standards traceable to NIST. A certificate is provided with each hydrometer assuring that the user receives a quality instrument. The Brix scale is used in sugar refineries, and also often encountered on wine labels where it describes the sugar content of the grape juice from which the wine was made. Each two degrees Brix of the juice leads to about 1% alcohol by volume in the wine. The Balling scale is numerically the same as the Brix.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96811

The HI 96811 Digital Refractometer is a portable meter measuring the refractive index of samples in order to display sugar content, 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 HI 96811 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 HI 96811 has a range of 0 to 50 %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). It’s dimensions are 19.2(W) x 10.2(D) x 6.7(H) cm, with a mass of 420 g. Hanna manufactures additional refractometers which measure sugar content in units such as degrees Baumé, degrees Oechsle, degrees KMW (utilized in the Austrian, German, and Swiss winemaking industries) and measure percent alcohol. 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. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH poc...
