The Atago 3489 PR-40DMF Palette is a digital refractometer that measures dimethylformamide concentration (0.0 to 40.0% [w/w]), has + or - 0.3% measurement accuracy, automatic temperature compensation (ATC), a user-scale function, and external light interference (ELI). A refractometer measures the refractive index of a liquid or solid in a sample, converts it to concentration in units of percent by weight, and displays the results. Refractometers are commonly used in the optical, chemical, geological, ecological, culinary, food and beverage, pharmaceutical, and educational industries, and for water-testing applications.
This refractometer features programmable user scales that enable control of various liquid concentrations. The unit has a digital, LED-illuminated display of salinity concentration, or temperature in degrees C. It has external light interference (ELI) technology for accurate measurement near windows or outdoors. The unit measures from one drop of sample, and provides measurement results in three seconds, in a sample measurement temperature range of 5 to 40 degrees C. It has ATC for accuracy, and can be calibrated with distilled water. The unit’s sample well is made of stainless steel 316 for durability. The refractometer works with a 9V battery (included), and comes with a carrying case. The 3489 PR-40DMF has Ingress Protection (IP)-64 rating for protection against dust and liquids.
