ADVANCE R-8 Abbe Refractometer
ADVANCE Model R-8 Abbe Refractometer with Digital Temperature Indicator:
The ADVANCE Model R-8 Abbe Refractometer is a high-precision, handy measuring instrument designed for critical measurement applications in laboratories and industry. This model, enhanced with a Digital Temperature Indicator, provides accurate and repeatable refractive index and Brix measurements, crucial when sample temperature must be precisely noted.
Core Design and Optical Excellence:
The R-8 features completely sealed optics ensuring reliable operation even in tropical regions and under extreme operating conditions. Operational efficiency is maximized through a single eye-piece, which allows the user to simultaneously read the calibrated scale and view the demarcation shadow line. Focusing the boundary line of total reflection and taking the reading is performed within the same field of view, making the operation efficient.
Robust and User-Friendly Mechanics:
A defining feature of the Model R-8 is its horizontal prism, which facilitates the easy application of test samples and prevents test liquids from flowing down. The prism box itself is constructed from Stainless Steel, allowing for the testing of highly corrosive materials without fear of damaging the box. The instrument also includes a compensator designed to offset dispersion inherent in the medium under test. The compact overall design safeguards all delicate optical and mechanical parts against potential mechanical, thermal, or chemical damage.
Precision Temperature Management:
Refractive Index measurements are highly dependent on temperature. To ensure accuracy, the R-8 is equipped with several features for strict temperature control:
• Water Jacketed Prism Box: The prism mounts are equipped for fluid circulation, allowing connection to a Thermostatically Controlled Circulating bath for maintaining constant temperature during measurements.
• Integrated Digital Temperature Indicator (DTI): The DTI is a compact and rugged system providing easy and accurate determination of the prism temperature, which is essential for precise results.
• High Resolution: The DTI utilises a PT-100 probe offering a resolution of 0.1 °C with a repeatability of 0.5 °C.
• Clear Display: The temperature reading is presented on a bright LED or LCD display.
Measurement Versatility and Illumination
The R-8 offers dual graduations for Refractive Index ($n_D$) and Brix Percentage (Sugar), along with the capability for the measurement of Dispersion.
Illumination can be managed based on sample type, offering the advantage of operating on either Transmitted light or Reflected light. This flexibility is particularly useful when measuring highly coloured samples, plastic substances, or dark or solid samples accurately.
When fitted with the compact lighting system (often integrated with the digital indicator unit), the need for an external light source is eliminated. An intensity controller is built into the indicator panel, allowing the user to adjust the Prism Box illumination intensity to achieve a sharp and well-defined demarcation shadow.
Applications:
The ADVANCE Model R-8 Abbe Refractometer is ideal for quality control and research in various fields, including Pharmaceuticals, Sugar production, Paper manufacturing, Educational Institutes, and essential oil analysis.
