ERMA Hand Refractometer 0–10% Brix with Automatic Temperature Compensation (ATC)

Short Description

ERMA 0–10% Brix Hand Refractometer is a compact, portable optical instrument designed for quick measurement of sugar concentration in low-concentration liquid samples. Its 0–10% Brix range and 0.1% Brix graduation make it suitable for food, beverage, laboratory, agricultural and process-quality applications.

Technical Specifications

*Specifications such as weight and accuracy can vary by ERMA model/version; verify against the manufacturer's supplied specification before publishing as a guaranteed specification. Available listings report approximately 290 g and ±0.2% for an ERMA 0–10 Brix model.

Principle of Operation

The refractometer determines Brix by measuring how light is refracted when it passes through the sample. The resulting optical boundary is viewed through the eyepiece and read directly against the Brix scale.

What Does 0–10% Brix Mean?

The Brix scale indicates the approximate concentration of dissolved sucrose in a solution. For example, a reading of 5° Brix corresponds approximately to 5 g of sucrose per 100 g of sucrose-water solution under the defined reference conditions. For samples containing substances other than sucrose, the Brix value should be treated as an indication of total soluble solids rather than an exact sucrose concentration.

Applications

Food & Beverage

• Fruit juices
• Soft drinks

• No electrical power required
• Automatic temperature compensation
• Fine 0.1% Brix scale graduation
• Suitable for low-Brix samples
• Small sample requirement
• Useful for field and laboratory measurements
• Robust metal construction

How to Use

1. Open the daylight plate.
2. Clean the prism surface with distilled water and a soft lint-free tissue.
3. Place a few drops of the sample on the prism.
4. Close the daylight plate gently so the sample spreads evenly.
5. Point the instrument toward a suitable light source.
6. Look through the eyepiece and focus the scale.
7. Read the Brix value at the boundary between the light and dark regions.
8. Clean and dry the prism after measurement.

Calibration

Before routine measurements, check the instrument using distilled/deionized water according to the manufacturer's instructions. The reading should correspond to the appropriate zero reference. If adjustment is required, use the supplied calibration mechanism.

Important Usage Notes

• Clean the prism before and after every measurement.
• Avoid scratching the prism surface.
• Do not immerse the complete instrument in liquid.
• Allow samples with significantly different temperatures to stabilize as appropriate.
• ATC compensates for temperature effects within its designed operating range; it does not replace proper sample handling.
• Brix readings on non-sucrose solutions represent an approximate soluble-solids indication and may not equal actual sugar concentration.
