The RA-620 Refractometer is the ideal choice for quick and reliable measurements of liquid samples with a refractive index in the range between 1.32 and 1.70.
This instrument is ideally suited for the quality control and concentration measurements in the pharmaceutical, chemical, aroma, flavor and fragrance and petrochemical industry. It conforms to the specific requirements, methods (like US, European Japanese and UK Pharmacopoeia), norms (like ASTM 1218) and regulations of these industries.
Maximal efficiency with minimal space requirements:
The RA-620 fits on a standard A4 page.
High-grade aluminium casing – no plastic.
Optimal ease of use
thanks to a large color touch screen and sophisticated barcode features.
Comfortable handling through ergonomically favorable design
The shallow and therefore easy to clean measuring cell is located in front of the display. The sample cover, when opened, protects the display against splashes.
Quick and highly accurate temperature control
in the range of 5 to 75°C by means of a solid state thermostate developed based on KEM’s long lasting expertise in thermal conductivity measurement. Highly accurate measurements only take a few seconds to perform.
Extremely simple user guidance ensures fail safe operation
Visual indication of concentration ranges, easy to follow step-by-step guide for calibrations and the visual representation of the Abbe image to get aware of problematic samples or insufficient cleaning are just a few examples of the features which ensure reliable results.
Ideally suited for concentration measurements
In addition to the already bulit-in scales up to 100 concentration tables can be stored in the instrument.
Hassle-free, operating system independent connection to PC – no special software required.
Whether you are using Windows, OSX or Linux: All you need to control the instrument and to collect the measuring data is your preferred Web browser like Firefox, Google Chrome or Internet Explorer. If you do not want to connect your instrument directly to a PC, measuring data can easily be transferred by means of an USB memory stick.
