Description

The Digital UREA Refractometer (IMPA 651349) is a precision measuring instrument designed to determine the concentration of UREA solutions, commonly known as AdBlue® or Diesel Exhaust Fluid (DEF). It provides fast and accurate digital readings, allowing users to quickly verify fluid quality and ensure proper concentration before use.

Unlike traditional optical refractometers, this digital model delivers clear numerical readings on a large LCD display, reducing operator interpretation errors while improving testing efficiency.

Designed for portability and convenience, the instrument features a lightweight handheld design that is suitable for use in workshops, service centres, marine vessels, fleet maintenance facilities and industrial environments. Simply place a small sample onto the measurement prism, press the measurement button and obtain an accurate result within seconds.

In addition to measuring UREA concentration, the instrument also displays refractive index and sample temperature, providing additional measurement data for quality verification.

The model is commonly referenced by its IMPA purchasing code 651349, making it an excellent choice for marine operators and purchasing departments sourcing equipment using International Marine Purchasing Association (IMPA) codes.

Whether you are inspecting incoming AdBlue supplies, verifying mixed UREA solutions or performing routine maintenance checks, the Digital UREA Refractometer offers a fast, reliable and user-friendly solution.
