Description

The Digital Brix+Salinity Refractometers YGA1557 and YGA1561 are advanced, multi-functional devices designed to measure both the concentration of soluble solids (including almost 100% sugar) and salinity levels in aqueous solutions. Ideal for use in food, beverage, and chemical industries, these refractometers are highly effective in measuring sugar content in solutions such as fruit juice, syrups, purees, and more. In addition, they are capable of measuring the salinity of solutions like sodium chloride and seawater, as well as the refractive index of various liquids.

These refractometers feature Automatic Temperature Compensation (ATC), which ensures that measurements remain accurate without needing manual adjustments for temperature variations between 0-40°C (32-104°F). With a minimum sample volume of just 2 drops, the digital display quickly provides accurate readings of Brix and salinity, making them ideal for quick, reliable testing. The devices are built with a stainless steel ring and flint glass prism, and they feature a waterproof IP65 rating, ensuring durability even in challenging environments.

Market Price

The Digital Brix+Salinity Refractometers YGA1557 and YGA1561 typically range in price from $218 to $230, depending on the model and features. These refractometers provide an excellent balance of functionality and affordability, making them an excellent investment for professionals in food production, aquaculture, chemical testing, and other industries requiring precise measurements of soluble solids and salinity levels.

Frequently Asked Questions

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

  • The ATC feature automatically adjusts for temperature changes between 0-40°C, ensuring that the refractometer provides accurate readings without needing manual temperature adjustments.

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

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

• How much sample is required for a measurement?

  • Only about 2 drops of the sample are needed for accurate measurements, making it convenient and quick to use.

• 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 field applications, the YGA1557 and YGA1561 refractometers are invaluable tools for professionals needing to measure sugar content in various food and beverage products, such as in brewing, fruit juice production, or syrup manufacturing. They are also commonly used in marine environments for measuring seawater salinity, and in aquaculture for monitoring water quality. These devices help ensure that solutions and mixtures are at the desired concentration, improving product quality and consistency in production processes.

Recommendations

To ensure long-lasting and reliable use, it’s recommended to regularly clean the prism and sample cell to avoid 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. Calibrate the device using pure water to reset the refractometer before measuring unknown samples to ensure precise readings.
