Selecting a Refractometer for the Food and Beverage Industries.
Refractometer for Food Quality Control
Measurement of Brix is central to food manufacturing. Consistent Brix measure is key to product consistency. Food product profit margins are tight, so careful monitoring of the quality of incoming raw material and also strict monitoring of how much of that raw material is used in the process are the main drivers of factory profit. Food and beverage refractometer users require an instrument with an easy to clean sample well, reliable temperature control, and rugged construction. Do you measure…

Gründe für die Wahl von Rudolph
- Accuracy in the second decimal place in Brix means the ability to stay closer to specification.
- Durch die Temperaturregelung kann das Gerät mit rückführbaren Referenzen kalibriert werden, um ISO- und ähnliche Normen zu erfüllen.
- Flat, easy clean prism means better results even when used by non-laboratory trained operators.
Typical Rudolph Refractometer for Food Users
- Cargill uses Rudolph Refractometers in ingredient manufacturing plants globally.
- Mars Wrigley uses Rudolph instruments to check the quality of tomato products for prepared meals.
- Nestle uses Rudolph to check the quality of tomato products for prepared meals.
Refractometer for Food Feature Highlight
Flat, easy to clean prism — No matter how good the refractometer for food is, the results will only be right if the instrument is clean. Rudolph’s flat prism design makes cleaning easy, even with sticky syrups. The flat low profile sample well with a sample volume of less than 1ml is easily cleaned by wiping with a common paper towel. The J57 single cleaning surface with scratch-proof sapphire prism makes this a popular choice for high throughput food laboratories.

Messbereich: 1,32 - 1,53 RI; 0 - 95% Brix Genauigkeit:0,00004 RI, 0,03 Brix Elektronische Temperaturregelung: N/A Temperaturkorrektur: Gemäß ICUMSA |
Very fast measuring refractometer for food, sugar, and beverage industries, perfect for high throughput applications where temperature correction and a highly durable bench-top refractometer are required. |

Measurement Range: 1.33 – 1.53 RI; 0 – 100% Brix Accuracy:0.00004 RI, 0.01 Brix Electronic Temperature Control: Fixed temperature selection: 20°C and 25°C |
Brix results can only achieve accuracy in the real world if the sample area is cleaned properly. Rudolph’s shallow prism design has no corners or steep angles to trap sticky samples thus avoiding or reducing the problem of cross contamination between samples. The simple, easy to use user interface with large measure button and key lock out feature makes it a popular choice for busy factory labs. Gloved hands and elbows like the big measure key. |

Measurement Range: 1.33 – 1.53 RI; 0 – 100% Brix Accuracy:0.00004 RI, 0.01 Brix Electronic Temperature Control:Flexible temperature selection between 15°C – 50°C |
The J157-CC with non-contact cover (CC) and Auto Measure (AM) are popular option choices for food applications where the sample must be protected from a harsh environment and custom scales are required. Auto Measure (AM) allows for easy measurement on/off by just lifting the presser cover to stop a measurement and closing the cover to start a measurement. |

Measurement Range: 1.33 – 1.53 RI; 0 – 100% Brix Accuracy:0.00004 RI, 0.03 Brix Electronic Temperature Control:Flexible temperature selection between 15°C – 100°C; TB option: allows 15°C – 110°C with one hour boost to 120°C |
J357 is best for high temperature food applications where the product is more stable when measured at a high temperature. For example, the J357 temperature control system is set for 70°C and temperature correction is set for 20°C. The J357 heavy duty temperature control system ensures the sample stays at 70°C while the instrument displays a temperature corrected result of what the sample would read if it were 20°C. |
