Atago Hand-Held Refractive Index Refractometer MASTER-RI (Cat. No. 2612):
The MASTER-RI is a specialized analog refractometer belonging to the robust Atago MASTER-Series. It is engineered specifically as a refractive-index model, providing reliable and precise measurements across a range of 1.435 to 1.520. This portable instrument is crucial for professionals requiring quick and accurate refractive index testing in diverse environments, from the laboratory to the field.
Key Applications:
The MASTER-RI is primarily used for measuring the refractive index of challenging samples, including:
• Oils and Petroleum Products: Vegetable oil, petroleum, and oil slicks.
• Chemical Industries: Management of refractive index for cleaning solutions, antifreeze solutions, brines, snow melting agents, and cosmetics.
• Industrial Fluids: Suitable for various industrial applications where monitoring oil composition or general liquid index is essential.
Design, Optics, and Usability
The MASTER-RI combines high-quality optics with a durable, user-friendly design:
• Robust Construction: The unit features a die-cast aluminum metal body, providing excellent resistance to heat and organic solvents.
• Superior Visibility: It is engineered to provide a clear and crisp boundary line on its analog scale, ensuring accurate readings even when measuring dark, milky, opaque, or oily samples. The high-contrast display enhances visibility.
• Simple Operation: Being a hand-held analog unit, it operates using ambient light and requires no external power source. Measurements are quick and require only a small sample size of 2 to 3 drops.
• Hygienic Grip: The streamlined design includes a smooth outer shell grip that is easy to clean, reducing the possibility of food and sample entrapment and preventing bacterial growth.
• Portability: The compact, telescope-shaped design (approximately 16.8 cm long) ensures ease of use and handling in the field. The unit typically includes a protective storage case for safe transport.
• Temperature Control: This model utilizes manual temperature compensation for measurement accuracy.
