EI-DVI Model 305 Digital Visible Spectrophotometer | 340-960 nm | Accurate Lab Analysis
EI-DVI
The ATAGO PAL-S Digital Handheld Refractometer is a highly advanced portable Brix meter engineered for stable, repeatable, and highly accurate measurement of difficult food and beverage samples. Designed and manufactured in Japan, the PAL-S belongs to the globally trusted ATAGO PAL™ Series and incorporates innovative Mode S™ Technology, specifically developed to minimize unstable readings commonly encountered with opaque, cloudy, fatty, dark, or emulsion-based samples.
Unlike conventional handheld refractometers that often produce fluctuating boundary lines and inconsistent readings, the PAL-S digitally analyzes measurement stability using an intelligent internal algorithm. This allows laboratories, dairy processors, food manufacturers, beverage industries, and quality control departments to obtain dependable Brix readings with improved repeatability and reduced operator interpretation error.
The PAL-S refractometer is particularly suitable for measuring milk, yogurt, soy milk, ice cream, condensed milk, emulsions, dairy products, and high-viscosity food samples. Its fast measurement speed delivers accurate Brix values within approximately three seconds using only 2–3 drops of sample, significantly improving laboratory productivity and process efficiency.
Engineered for field and laboratory environments, the instrument features a compact ergonomic design weighing only 100g for convenient one-handed operation. Its IP65-rated waterproof and dust-tight construction supports hygienic operation and allows the sample stage to be safely rinsed under running water. The hygienic structure also aligns with HACCP, GMP, and GLP operational requirements for food safety and laboratory quality assurance.
The integrated Automatic Temperature Compensation (ATC) system ensures accurate Brix measurement across a broad temperature range of 10°C to 100°C, even when testing hot food products. For enhanced hot sample measurement stability, the included MAGIC™ adaptor rapidly cools high-temperature samples and reduces evaporation effects.
Additional reliability is provided through ATAGO’s patented External Light Interference (ELI) technology, which minimizes inaccurate measurements caused by intense outdoor or direct lighting conditions. Combining precision optics, intelligent stability analysis, rapid digital measurement, and exceptional portability, the ATAGO PAL-S offers an ideal solution for modern food quality control, dairy testing, beverage analysis, and industrial laboratory applications.

What is the ATAGO PAL-S Digital Handheld Refractometer used for?
The ATAGO PAL-S Digital Handheld Refractometer is designed for accurate Brix measurement of difficult food samples including dairy products, emulsions, soy milk, yogurt, ice cream, cloudy liquids, and dark samples. It provides fast and stable digital readings for food quality control and laboratory testing.
The PAL-S is widely used in dairy industries, beverage manufacturing, food processing laboratories, research facilities, and industrial quality control departments requiring reliable refractive index and Brix analysis.
What makes the Mode S™ Technology different from standard refractometers?
Mode S™ Technology uses an advanced internal algorithm to reduce unstable readings caused by opaque, fatty, cloudy, or emulsion samples. This improves repeatability and eliminates the need for repeated measurements or visual interpretation of blurry boundary lines.
Traditional refractometers often produce fluctuating results with difficult samples, whereas the PAL-S digitally stabilizes the measurement and displays a consistent numerical value for improved analytical confidence.
Can the ATAGO PAL-S measure hot food samples?
Yes, the ATAGO PAL-S can measure hot samples up to 100°C using its Automatic Temperature Compensation system and included MAGIC™ adaptor. This allows stable and accurate Brix analysis for heated food and beverage samples.
The MAGIC™ adaptor helps rapidly cool high-temperature samples while minimizing evaporation, improving measurement consistency and reducing thermal influence during testing procedures.
Is the PAL-S refractometer waterproof?
The PAL-S features an IP65-rated waterproof and dust-tight construction that allows the sample stage to be rinsed safely under running water. This hygienic design supports routine cleaning and long-term industrial use.
The robust structure is ideal for demanding food processing environments and supports compliance with HACCP, GMP, and GLP laboratory quality standards.
How fast does the ATAGO PAL-S provide Brix results?
The ATAGO PAL-S delivers highly accurate Brix readings in approximately three seconds using only 2–3 drops of sample. This rapid analysis capability improves laboratory productivity and production line efficiency.
The instrument also supports continuous measurement functionality for difficult samples requiring additional stability analysis using the integrated Mode S™ technology.
