Sample Brix by density Brix by refrac. Top of page. Download our free application note.

Type of Instrument. Hydrometer, learn how to choose it, the definition, advantages and more. Main Applications. Quick checking of Brix by density value in quality control laboratories Suitable for repeated measurements of similar kinds of samples wine, beer, juices due to the limited measuring range Not suitable for expensive samples large volume required. Learn how to choose, use and calibrate hydrometers. Simple, inexpensive Quick check of an approximate value. User-dependent results Takes a long time for temperature equilibration Small measuring range, typically takes 20 hydrometers to cover a wide measuring range Large sample volume required mL to mL Difficult to clean Breakable.

Pycnometer, learn how to choose it, the definition, advantages and more. Learn how to choose, use and calibrate pycnometers. Educational purposes in technical schools or universities Production control where more precision is required Analytical labs; not suitable for expensive samples as a large volume is required.

User-dependent results Pycnometers are calibrated for a certain temperature, e. ABBE optical Refractometer, definition, main applications, advantages and more. Quick checks of a "rough" refractive index value, especially for Brix measurements in beverages, fruit, jam, honey and other sugar-based products Testing blood and urine Heat transfer fluids as ethylene and propylene glycol antifreeze chemicals Cutting fluids and urea.

Small measuring range requires several portable refractometers to cover a wide range No or external thermostating Operator-dependent readings, therefore limited accuracy No built-in measurement protocols. Digital Refractometers portable and benchtop. Brix digital meters, definition, applications, advantages and more.

Learn more about the benefits of portable and benchtop refractometers. Learn more about the refractive index principle. Quality control of raw materials and final products in a wide variety of industries and segments, including: Food and beverage Chemicals Pharmaceuticals Cosmetics Flavors and fragrances Petroleum products.

Learn about applications for refractometers. Easy to use Small sample volume Automatic measurement means results are operator-independent Built-in product management with automatic quality control Possibility to connect with other instruments for multiparameter measurements Applicable to benchtop meters only.

Higher cost in comparison to hydrometers, pycnometers or optical handheld refractometers Portable refractometers have no thermostating, only temperature compensation.

Digital Density Meter portable and benchtop. Brix measurement with density meters. Watch our animation about the digital density measurement principle. Quality control of raw materials and final products in a wide variety of industries and segments, including: Food and beverage Chemicals Pharmaceuticals Cosmetics Flavors and fragrances Petrochemicals. Learn about applications for digital density meters. Easy to use Small sample volume Automatic measurement means results are operator-independent Built-in temperature compensation portables Built-in Peltier thermostat controls the temperature precisely benchtop devices Offers large storage capacity for results and the possibility of connecting to PC software for data management Sample can be measured directly from the sample container portables.

More expensive in comparison to hydrometers or pycnometers Portable density meters have no thermostating, only temperature compensation. Fast Brix Measurement. Learn how to measure sugar content during fermentation. Download our application note!

Learn how to measure the sugar content during fermentation. Winemaking sugar concentration in grape must Brewing concentration of dissolved solids, mainly sugars. Measure with. Density meter, pycnometer, hydrometer saccharimeter. Digital density meter, digital refractometer, pycnometer, hydrometer, manual refractometer.

For precise and simple measurements, the use of a benchtop digital density meter or a benchtop digital refractometer is highly recommended. Used to measure density of grape mainly in German-speaking countries. Steps Example 1 - Measure the specific gravity of your sample Result: 1. Brix by density. Brix Density Meter. Density Meter.
