The ATAGO PAL-1 BLT/i "Pocket" Refractometer is a compact and portable instrument designed for measuring Brix, which represents the weight percentage of sucrose in a solution. It can also be used to estimate the total dissolved solids in solutions where other soluble substances like salt, protein, and acids are present.
The PAL-1 BLT/i features an LCD that displays measurement results, prism temperature, and remaining battery charge. It is equipped with a START button to initiate measurements and a ZERO button for zero-setting. The device also incorporates Bluetooth Ver 4.0 for wireless communication, allowing it to export data to peripheral devices such as smartphones. This enables users to save and manage measurement data efficiently. The instrument includes Automatic Temperature Compensation (ATC), which corrects readings based on the prism's temperature within a specified range, ensuring accuracy even with varying sample temperatures.
To begin using the refractometer, users must first install two AAA alkaline batteries (1.5V) into the battery compartment, ensuring correct polarity. The battery compartment cover is secured by turning it clockwise with a coin. After battery replacement, it is recommended to zero-set the instrument. The device also allows users to set the date and time for accurate data logging.
For measurement, a small amount of sample (0.3 ml or more) is applied to the glass prism located in the center of the sample stage. For accurate readings, it is crucial to clean the prism with water and dry it thoroughly before applying the sample. After applying the sample, the START button is pressed to initiate the measurement. The instrument will display the Brix value, prism temperature, and battery charge on the LCD. If the sample is hot or cold, it is advisable to wait approximately 20 seconds before pressing START to allow the instrument to acclimate to the sample temperature, ensuring stable measurements.
The PAL-1 BLT/i supports zero-setting using distilled water. After applying distilled water to the prism, the ZERO button is pressed to calibrate the instrument. If an "Err" message appears during zero-setting, it may indicate insufficient distilled water or a dirty prism.
The Bluetooth functionality allows for data export. By pressing and holding the ZERO button, users can export measurement data, including time, data, and temperature, to a connected smartphone or other Bluetooth-enabled device. The ATAGO Logger app, available on the App Store, can be used to receive and manage this data. The app provides options to save, delete, or transfer data, and allows for the creation of PDF manuals.
The instrument provides various error messages to guide the user. For instance, "LLL" indicates a low battery, "HHH" signifies that the prism temperature is above the compensation range, and "---" suggests that the sample is outside the measurement range. "Err" messages can also indicate issues such as insufficient sample volume, dirty prism, or a failure in zero-setting.
Proper storage and maintenance are essential for the longevity and accuracy of the PAL-1 BLT/i. The instrument should be stored in a dry place, away from direct sunlight and heat sources, as exposure to humidity and heat can damage it. It is also important to avoid rapid changes in ambient temperature, strong vibrations, and extreme cold.
After each use, the sample stage and prism should be thoroughly cleaned and dried. Water can be used for rinsing, followed by drying with a soft cloth. For stubborn residues, a small amount of ethanol or mild soap can be used. Metal tools should not be used to clean the prism, as they can scratch the glass, leading to erroneous measurements. The instrument is water-resistant (IP65), but it should not be submerged in water.
The battery compartment cover should be loosened for air transportation to prevent potential issues. When the battery icon indicates a low power level, both AAA alkaline batteries should be replaced with new ones. It is advisable to check the expiration dates of batteries before purchase.
The body case of the instrument is made of resin and should not be exposed to water vapor or solvents, as certain solvents can cause damage. The device is warranted for one year from the date of purchase, but this warranty is void if the instrument has been disassembled by unauthorized personnel, shows water damage, has been dropped, or has suffered from battery leakage or misuse. Repair services are available for a fee after the warranty expires. When contacting customer service, it is important to have the serial number information ready.
