Saccharimeters – 4 Models To Meet Your Application Requirements

The Rudolph Saccharimeter product line, the AUTOPOL® 589, 880, 880 Plus, and 880T Automatic, Digital instruments 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 75 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.

— Arnel Negranza, Chief Chemist, Western Sugar, USA

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

Comprimentos de onda duplos

The most important feature of the AUTOPOL® IIZ, 880, 880 Plus and 880T 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.
Saccharimeter Purity Screen

Correção do comprimento da diluição e da pilha

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.
Sugar Concentration Screen

Calibração saccharimeter automática

Calibrar o AUTOPOL ® é rápido e simples. Primeiro, coloque uma placa de controle de quartzo Rudolph padrão de calibração nos trilhos ópticos e insira o valor da placa de quartzo na janela apropriada. Em segundo lugar, introduza a temperatura para corrigir a medição ICUMSA standard temperature of 20°C or the Tropical reference temperature of 27.5°C. Third, press Save and the calibration is complete. (See Technical Bulletin 913 for more details on Rudolph Calibration Standards)

Correção automática de temperatura

Temperature correction sugar testing
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:
Temperature Control Sugar Testing

  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.

 

 Choosing a Cell and a NIST Traceable ICUMSA Compliant Calibration Standard

Temperature Probe Insertion Options


All Autopol Saccharimeters come with a Temperature Probe so that sample temperature can be displayed and printed. The temperature probe is built into the sample compartment and can be inserted into the polarimeter cell.

Automation and continuous sampling


Cells are available in 25mm, 50mm, 100mm and 200mm optical path lengths with necessary fittings for any application.

Pour in sampling with temperature correction

Cells with stainless steel funnels and exit tubing are available in 50mm, 100mm and 200mm optical path lengths.

TempTrol™ Quartz Plates

Allow for temperature control and correction. Standard Quartz Plates allow for temperature correction only.

Popular Saccharimeter and Refractometer Combinations

Autopol 880 or Autopol 880T PLUS with J457 optics unit which can come in drop sample or with a Pour-In Funnel option (PTW). The refractometer optical unit shares the polarimeter display 

The J457-OM-CC is also quite popular with sugar factory labs. The non contact cover (CC) with built in electronic heating and cooling improves performance in harsh conditions. The J457 comes with the SmartMeasure™ solution that allows the operator to never touch the display.  The instrument instructs when to load and clean a sample.  The solution improves accuracy and reduces cleaning and loading errors. It is also very popular for factory environments where air temperature varies dramatically: cold at night and hot during the day.

 Measuring Purity with Ethanol

Purity software is standard on the Autopol® 589, 880, 880 PLUS and 880T, just add a Refractometer
and read BRIX, POL and PURITY simultaneously on the Autopol’s® large color backlit display.

Sample Specific Programs

All AUTOPOL® models come with purity software and an unlimited number of methods 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. dilution

Purity Software is standard on the Autopol® IZ and IIZ shown below with the J157-CC PLUS

Purity

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 method keys. The factory operator simply presses the preassigned method key to start measurement.
