Аtago PAL-2 is a high-range digital hand-held pocket refractometer designed for precise measurement of Brix (sugar concentration) in various high-concentration samples. This device is suitable for applications in the food and beverage, pharmaceutical, and chemical industries, among others. Its compact and ergonomic design allows for easy one-handed operation and portability.
Key features include Automatic Temperature Compensation (ATC) for accurate readings across a temperature range, an External Light Interference (ELI) warning, and an IP-65 rating for protection against dust and water jets, allowing for easy cleaning.

4.1. Calibration (Zero Setting)
For accurate measurements, calibrate the refractometer with water before use, especially if the ambient temperature has changed significantly.
- Ensure the prism surface is clean and dry.
- Apply a few drops of clean tap water or distilled water onto the prism surface, ensuring it covers the entire surface without air bubbles.
- Close the daylight plate gently.
- басыңыз НӨЛ button. The display will show "0.0%" or "CAL" briefly, then return to 0.0% Brix. This indicates successful calibration.
- Clean the prism surface thoroughly with a soft cloth or tissue.
4.2. Ченөө алуу
- Ensure the prism surface is clean and dry.
- Apply a few drops (approximately 0.3 mL) of the sample liquid onto the prism surface. Ensure the sample covers the entire surface.
- Close the daylight plate gently.
- басыңыз START button. The measurement will be displayed in approximately 3 seconds.
- Read the Brix value and temperature from the LCD.
- After measurement, clean the prism surface immediately with a soft, damp cloth or tissue, then dry it.
4.3. Automatic Temperature Compensation (ATC)
The PAL-2 features ATC, which automatically adjusts the Brix reading to a standard reference temperature (typically 20°C) based on the sample's measured temperature. This ensures accurate readings even if the sample temperature fluctuates between 10°C and 100°C.
4.4. External Light Interference (ELI) Warning
If direct light interferes with the measurement, the device will display a warning message. To resolve this, move the refractometer to a location with less direct light or shield the prism from strong light sources during measurement.
5. Техникалык тейлөө жана кам көрүү
5.1. Cleaning the Prism
Always clean the prism surface immediately after each use. Use a soft, damp cloth or tissue to wipe off the sample. For sticky or viscous samples, a small amount of warm water can be used. The IP-65 rating allows the unit to be washed under running water, but avoid submerging the entire device.
5.2. Жалпы тазалоо
Wipe the body of the refractometer with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing же дисплей.
5.3. Сактоо
Store the refractometer in its plastic storage case in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries if the device will not be used for an extended period to prevent leakage.
