Key Features
The new ultra compact lighting arrangement for Abbe Refractometer Model R - 8 eliminates the tedious process to arrange for an external light source to read the scale & view the demarcation shadow and is also provided with intensity adjuster to provide the best intensity. The lighting arrangement unit consists of 3 basis parts: Prism Illuminator, Scale Illuminator and Digital temperature Indicator cum Intensity Controller
- Single Eye-piece for reading the Scale and to view the Demarcation Shadow
- Completely sealed optics for operation in tropical regions and extreme operating conditions.
- Dual graduations of Refractive Index & Brix.
- Measurement of Dispersion of liquids with conversion table.
- Horizontal Prism to prevent flowing down of test liquid and for customer convenience.
- Water Jacketed Prism Box which can be connected to Circulating Thermostat for Temperature Maintenance.
- Compensator to compensate for Dispersion in the Medium under test.
- Compacting Lighting System for both Prism Box & Scale illumination

Accurate Measurement for Liquids and SolidsThis refractometer delivers reliable readings for a wide refractive index range, ensuring precise analysis of both liquids and solid samples. With a shadowline visual method, it is widely used for Brix and refractive index measurements in research and industrial labs.
Efficient Temperature ControlEquipped with an external thermostat arrangement, the device maintains prism temperature between 0C and 70C for consistent results, allowing users to handle varied environmental conditions and sample requirements.
User-Friendly OperationManual controls and easy zero calibration make the refractometer straightforward to use, even for technicians with limited experience. The analog scale allows for quick readings, while its robust build ensures reliability.
FAQs of Abbe Refractometer CLS:
Q: How is the refractive index measured using the Abbe Refractometer CLS?
A: The refractive index is determined visually via the shadowline method on the analog scale, allowing for precise and immediate readings in the 1.3000 to 1.7000 nD range.
Q: What types of samples can be tested with this refractometer?
A: It is suitable for both liquid and solid specimens. Only a small drop of sample is needed for each test, making it efficient for labs where sample volume is limited.
Q: When should temperature control be used during measurement?
A: Temperature control via the external thermostat is recommended when measuring samples sensitive to temperature variations or when working outside ambient conditions, to ensure accuracy in readings.
Q: Where can the Abbe Refractometer CLS be installed?
A: This equipment is designed for table-top mounting, ideal for laboratory and research settings. It requires a standard 220V AC, 50 Hz power supply and can be utilized in environments up to 85% relative humidity.
Q: What is the process for calibrating the refractometer?
A: Zero calibration of the refractometer is straightforward and can be performed easily before measurements, ensuring continued accuracy and reliability of results.
Q: What are the benefits of using a prism with a thermostat arrangement?
A: The thermostat arrangement enables precise control of prism temperature, leading to consistent measurement conditions and improved reproducibility of results, particularly for temperature-sensitive samples.
Q: How fast does the device respond during testing?
A: This refractometer provides immediate response to sample measurements, with manual operation allowing users to process tests quickly and efficiently.
