This is Rudolph’s most popular saccharimeter. It is used by 98% of all US sugar mills, 100% of all US customs labs and can be found in thousands of sugar mills around the world. It has 0.01 accuracy and is available in both 2 and 4-wavelength versions. Recommended for the sugar industry, the Autopol® 880 digital saccharimeter is a dual wavelength microprocessor-based digital saccharimeter capable of measuring at both 589 nm and 880 nm. The 880 nm ICUMSA Approved near infrared wavelength allows measurement of dark sugar factory juices, while the AUTOPOL® Automatic Saccharimeter Purity Mode allows simultaneous measurement and display of PURITY, BRIX, and POL.
Dual Wavelengths
The most important feature of the AUTOPOL® saccharimeter models IIZ, 880 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® 880 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 path-length cell.
Automatic Calibration
Calibrating an AUTOPOL® saccharimeter 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® 880 displays the temperature source and type of correction. Utilizing factory-programmed temperature coefficients the AUTOPOL® 880 can make the following types of temperature corrections:
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.
A 29°C sucrose sample in a Type 14 center fill glass cell can be measured by the temperature probe inside the sample chamber and corrected to 20°C.
A Quartz Plate measured at 25°C by the chamber temperature probe and then automatically corrected to 20°C.
Rudolph knows Sugar Technologists around the world demand 24-hour operation, 7 days a week for up to 9 months out of the year. They expect 0.02 °Z reproducibility and accuracy. Rudolph Research understands these demands and requirements because Rudolph has been serving the sugar industry since 1940. Throughout those sixty plus years, 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 consistent with Rudolph’s over 5,000 instruments installed worldwide, with many of those instruments still in operation after 25 years of service.
