These devices are essential for industries such as food, beverage, and chemical manufacturing due to their accuracy in determining sugar content in products like fruit juices, syrups, and purees. Additionally, they offer versatility by measuring salinity in solutions like sodium chloride and seawater, as well as the refractive index of diverse liquids.

Market Price

The Digital Brix+Salinity Refractometers YG1557 and YG1561 are competitively priced between $218 and $230, depending on the model and features. This price range balances advanced functionality with affordability, making these refractometers a valuable investment for professionals who require precise measurements in fields such as food production, aquaculture, and chemical testing.

Frequently Asked Questions

• How does the ATC (Automatic Temperature Compensation) work in these refractometers?

  • The ATC feature automatically adjusts for temperature fluctuations between 0-40°C, ensuring accurate readings without manual temperature adjustment.

• What types of samples can be measured with these refractometers?

  • These refractometers can measure Brix (sugar content) in liquids like fruit juice, syrups, and beverages, and salinity in seawater, brines, and other aqueous solutions.

• How much sample is required for a measurement?

  • Only about 2 drops of the sample are necessary to achieve accurate measurements quickly and efficiently.

• What is the accuracy of the readings?

  • The refractometers offer high precision, with an accuracy of ±0.2% for Brix, ±0.1% for salinity, and ±0.0003nD for refractive index.

Advantages and Disadvantages

Advantages:

• ATC functionality ensures consistent, accurate results regardless of environmental temperature.
• Minimal sample size required (just 2 drops), making it efficient and easy to use.
• Quick readings with a digital display for both Brix and salinity.
• Waterproof and durable design with an IP65 rating, making it suitable for rugged conditions.
• Versatile for multiple industries, including food production, aquaculture, and chemical testing.

Disadvantages:

• Limited to the 0-40°C temperature range—extreme conditions outside of this range may affect the accuracy.
• As a digital device, it requires batteries (1.5v AAA), which need to be replaced periodically.

Field Use

In practical scenarios, the YG1557 and YG1561 refractometers are invaluable for experts measuring sugar content in various food and beverage products, such as brewing, fruit juice production, or syrup manufacturing. They are also commonly used in marine environments to measure seawater salinity and in aquaculture to monitor water quality. These devices ensure solutions and mixtures are at the desired concentration, improving product quality and consistency in production processes.

Recommendations

To maintain optimal performance, regularly clean the prism and sample cell to prevent residue build-up that could affect measurement accuracy. After each use, simply wipe the device with a soft cloth and store it in a dry, safe location. For precise readings, calibrate the device using pure water before measuring unknown samples.
