Abbe Mark III Digital Abbe Refractometer


Entry Level Abbe Refractometer is Mainstay of Industrial & Academic Laboratories


The Reichert Abbe Mark III replaces the legendary Mark II Plus. It has all of the familiar features of the Mark II Plus together with new features usually found on more advanced refractometers.


The Mark III is a transmitted light refractometer which measures the light that passes through the sample as opposed to the light reflected off a surface of a fluid. A transmitted light refractometer, like the Abbe Mark III, will allow the user to view the actual shadow line. Transmitted light refractometers are preferable for some applications involving transparent, translucent, and semi-translucent liquids and solids that are difficult to measure on other types of refractometers.


Use it like you would the Mark II Plus; after placing your sample between the two prisms, simply look through the eyepiece, rotate the large side wheel until the shadowline intersects with the crosshairs, and then press the Read key.


The measurement will be displayed on the LCD screen along with temperature, date, and time. The measurement range of 1.3106 to 1.7000 (0.0 to 95.0% Solids) is one of the widest of any refractometer available. Measurement accuracy is +/-0.0001 refractive index (0.1% solids) is insured using software that automatically detects temperature equilibration.


You have a choice of controlling the instrument temperature with a water bath or using the built-in automatic temperature compensation in both percent solids and refractive index mode. The Mark III can hold 14 custom measurement scales in addition to refractive index and % Solids. The sample is illuminated using a special LED light source.


Note: Unit is supplied with 2 x RS232 serial communication ports that allow connectivity to a PC and printer.
