Sugar Testing Saccharimeter
The Autopol 589 saccharimeter from Rudolph Research Analytical provides the same features, measuring speed and accuracy of the Autopol 880 but at the single wavelength of 589 nm. For 0.01°Z accuracy sugar testing and payment.
589 nm is for countries and applications where lead or other suitable clarifiers are being used. This model works at 589 nm and is not compliant with ICUMSA testing at 880 nm.
Dual Wavelengths
The most important feature of the Autopol 589 is the 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 Autop[ol is quick and simple. First, place a quartz control plate calibration standard on the optical rails and enter the quartz plate value in the appropriate window. Then 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. Finally press Save and the calibration is complete.
Automatic Temperature Correction
Utilizing the temperature probe located in the measurement compartment, temperature correction to 20ºC, 27.5ºC or other user defined temperature is performed easily and automatically by the Auyopol 589. 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:
- 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 saccharimeter 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
Temperature Probe Insertion Options
The temperature probe in the sample compartment can be inserted into the polarimeter cell.
Automation and Continuous Sampling
Cells are available in 25mm, 50mm, 100mm and 200mm optical path lengths with fittings for any application.
Pour in Sampling
Stainless steel cells are available in 50mm, 100mm and 200mm optical path lengths.
Optics
No matter which Autopol saccharimeter you choose it will feature the same high quality optics. While other manufacturers use Polaroid plastic dichroic sheet polarizers, Rudolph Research employ Glan Thompson Calcite polarizers in all its models. High quality polarizing prisms are important because they are two of the most critical optical components in a saccharimeter. Polaroid polarizers are made of a polymeric plastic where the molecules are stretches and oriented in a specific direction so as to linearly polarize light. These types of plastic sheet polarizers are cheap, vulnerable to heat and warping, deteriorate from moisture and have greater light absorption than Calcite polarizers. In many cases the plastic polarizers must be replaced in as little as 3 years whereas Rudolph guarantees its prisms over the life of the Saccharimeter. Glan Thompson calcite polarizers are comprised of a carbon crystalline structure similar to diamond and have excellent light transmission characteristics. The quality of these prisms is such that they are guaranteed over the life of the saccharimeter.
Purity Software Definitions
The Autopol 589 always displays Purity as if it were reading a 1 normal solution as defined in SPS-1: 3.1 The “normal sugar solution” is defined as 26.0160 g of pure sucrose weighed in vacuo and dissolved in water at 20.00°C to a final volume to 100.000 cm3. This corresponds to 26.000 g weighed in air under normal conditions (1013 mbar, 20°C, 50% relative humidity) and dissolved in water to a final volume of 100.000 cm3. Therefore, Rudolph displays:
% Sucrose = °Z reading corrected for dilution
Example: a 1/4 normal wt. solution reading 13.70°Z will read (4 x 13.70°Z) 54.80% Sucrose.
%RDS-OP = Refractometer dissolved solids or Brix prior to dilution
Example: a 3:1 dilution having a refractometer Brix reading of 14.30 would read 42.90 %RDS-OP (14.30 Brix x 3)
%PURITY = %Sucrose x 100 x apparent density polynomial, %RDS-OP
Also available the Autopol IZ and IIZ, the Autopol 880 and 880T and the 880 Plus and 880T Plus.
