Autopol IZ & II Z Saccharimeters

Saccharimeters – 4 Models To Meet Your Application Requirements

The AUTOPOL® 589, 880, 880 Plus, and 880T Automatic Digital Saccharimeters provide 0.01°Z repeatability and accuracy, time proven measurement technology and the critical features necessary for today’s sugar analysis.

Saccharimeters with the features Sugar Chemists Demand

Rudolph Research Analytical knows that Sugar Technologists around the world demand 24 hour operation, 7 days a week. Regardless of the 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 an Automatic 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.

Autopol® 589, 880, and 880T, and 880 Plus Saccharimeter Important Features

Dual Wavelengths

The most important feature of the AUTOPOL® models IIZ, 880, 880 Plus and 880T are their ability to measure at two wavelengths: 589 nm and 880 nm (NIR). Select 589 nm for conventional analysis using chemicals or lead clarifiers, or select 880 nm for polarimetric sugar measurements in the near infrared (NIR). 880 nm is above the absorption level of most dark sugar factory solutions allowing measurement of filtered but non-lead clarified juices. The dark sample measurement bar gets darker in proportion to the darkness of the sample being measured. When the bar is completely dark the instrument has reached its measurement limit.

Dilution and Cell Length Correction

Whether your sugar analysis requires a 25mm, 50mm, 100 mm or 200 mm cell, whether you use 1/2 normal (13g/100ml), 1/4 normal (6.5g/100ml) or full weight sugar solutions, the AUTOPOL® 589, 880, 880 Plus and 880T  saccharimeters provide the correct multiplier to display the reading as if the sample were prepared as a 1 normal solution in a 200 mm optical pathlength cell.

Automatic Saccharimeter Calibration

Calibrating the AUTOPOL® is quick and simple. First, place a Rudolph Quartz Control Plate calibration standard on the optical rails and enter the Quartz Plate value in the appropriate window. Second, enter the temperature to correct the measurement to either the ICUMSA standard temperature of 20°C or the Tropical reference temperature of 27.5°C. Third, press 2 buttons and calibration is complete. (See Technical Bulletin 913 for more details on Rudolph Calibration Standards)

Automatic Temperature Correction

All AUTOPOL® Saccharimeter models have a temperature probe in the measurement compartment. The probe can be inserted into all 14 style, 40T style, 41T style and 33 style measurement cells.

The AUTOPOL® displays the temperature source and type of correction. Utilizing factory programmed temperature coefficients the AUTOPOL® can make the following types of temperature corrections:

  1. A 30° C sucrose sample can be measured by the temperature probe and corrected to 20°C or 27.5°C or a customer defined temperature.
  2. A 29°C sucrose sample in a Type 14 center fill glass cell can be measured by the temperature probe inside the saccharimeter sample chamber and corrected to 20°C.
  3. A Quartz Plate measured at 25°C by the chamber temperature probe and then automatically corrected to 20°C.
