Regardless of the necessary for sugar analysis. accuracy and budget demands, Rudolph Research has a solution. The reason we understand the sugar industry’s demands and requirements is because Rudolph has been serving the industry since 1940. Throughout those fifty plus years of service, Rudolph has dedicated itself to manufacturing quality instrumentation and providing superior technical and service support, both directly and through its worldwide dealer network. This dedication is demonstrated by Rudolph’s installed base of over 5,000 instruments worldwide, with many of those instruments still in operation after 25 years of service. Why Choose A Rudolph Saccharimeter? Just listen to our customers: “...how pleased we are with the AUTOPOL instrument here at Lula-Westfield. Its performance has proven to be both reliable and accurate...” – A.H. Newchurch, Jr., Chief Chemist, Lula-Westfield, USA “...the biggest difference I’ve seen having the AUTOPOL 880 is how stable the readings are even with dark samples. There is no guessing the final answer.” – Arnel Negranza, Chief Chemist, Western Sugar, USA Autopol® 589, 880, 880 Plus and 880T Important Features Dual Wavelengths Automatic Dark sample measurement bar The most important feature Calibration of the AUTOPOL® models Calibrating the IIZ, 880, 880 Plus and 880T AUTOPOL® is quick have the ability to measure and simple. First, place a at two wavelengths: 589 nm Rudolph Quartz Control and 880 nm (NIR). Select Plate calibration standard 589 nm for conventional on the optical rails and analysis using chemicals or enter the Quartz Plate lead clarifiers. Select 880nm value in the appropriate for polarimetric sugar window. Second, enter measurements in the near the measurement infrared (NIR) which is above the absorption level of most dark sugar temperature. Third, press 2 buttons and calibration is complete. factory solutions thereby allowing measurement of filtered but non-lead clarified juices. The dark sample measurement bar gets darker in Automatic Temperature Correction proportion to the darkness of the sample being measured. When the bar All AUTOPOL® models have a temperature probe in the measurement is completely dark the instrument has reached its measurement limit compartment. The probe can be inserted into all 14 style, 40T style, 41T style and 33 style measurement cells. Dilution and Cell Length Correction The AUTOPOL® displays the temperature source and type of correction. Whether your sugar analysis requires a 25mm, 50mm, 100 mm or Utilizing factory programmed temperature coefficients, the AUTOPOL® 200 mm cell, whether you use 1/2 normal (13g/100ml), 1/4 normal can make the following types of temperature corrections: (6.5g/100ml) or full weight sugar solutions, the (1) A 30° C sucrose sample can be measured by the temperature probe AUTOPOL and corrected to 20°C or 27.5°C or a customer defined temperature. ® 589, 880, 880 Plus and 880T (2) A 29°C sucrose sample in a Type 14 center fill glass cell can provide the correct be measured by the multiplier to display the temperature probe reading as if the sample inside the sample were prepared as a 1 chamber and corrected normal solution in a 200 to 20°C. mm optical pathlength cell.

Autopol® 880 Dual J457 Wavelength Saccharimeter Refractometer Large LCD Backlit Display Shown with drop Shown with pour in sampling (Pour in sampling sampling is optional) Sample Specific Programs The AUTOPOL® models 589, 880, 880 Plus and 880T come with PURITy software and an unlimited number of sample specific programs which can be pre-defined for specific juices. This capability is advantageous in factory environments where the same type of samples are repeatedly measured. These programs allow for input parameters such as: multiplier, wavelength, and temperature correction to be prespecified. The PURITy software and a Refractometer also allow dilution on a weight/weight or weight/ volume basis which can also be prespecified for each sample name. Each program can be labeled with an alphanumeric and assigned to one of the function keys. The factory operator simply presses the preassigned function key to start measurement.
