The 2909 has a resolution of 0.0001 g/cm3, repeatability of 0.0001 g/cm3 and an accuracy of 0.0003 g/cm3 with a single calibration and measurement through multiple temperatures and 0.0002 g/cm3 with a single calibration at the measurement temperature.

RUDOLPH DENSITYMETER DDM RANGE: All the models of the DDM range are totally automatic, digital and have a built-in, touch-sensitive screen. They can control the temperature of the sample through electronic heating and cooling – Peltier method. The VideoView which is patented in the name of Rudolph comes with the basic unit. The entire U-tube is also scanned with a 10X camera. This ensures even the smallest bubbles to be magnified 10 times and the images are shown live in the screen. The range is between 0 – 3 g/cm3. The min volume of sample required is 1ml. The systems are equipped with 5 USB Ports, 2 RS232 Ports, Ehternet Port for Network Connection, Keyboard, Barcode Scanner, Mouse, Network capabilities.
They have a built-in 8GB Non-removable Compact Flast Internal Memory and the entire system would be driven by Embedded Win 7 OS. With calibration in one temperature the system works throughout the temperature range.

DDM2909: This is the top-of-the line system with a resolution of 0.0001 g/cm3, repeatability of 0.0001 g/cm3 and an accuracy of 0.00035 g/cm3.

MODEL J457:  The top-of-the line model J457 has many intelligent features inbuilt.  The range, resolution, repeatability and the accuracy are the same as 357. The temperature range of the sample is 10 Deg C to 110 Deg C.  The builtin Smart Measure identifies (a)  whether there is any sample residue on the prism surface (b)  whether the amount of sample in the prism is sufficient for measurement (c)  whether there is any sample contamination or improper cleaning (d) whether there are air bubbles in the sample etc..

MODEL J357:  J357 has a range of 1.26 to 1.72RI / 0 – 100Brix with a resolution of 0.00001RI / 0.01 Brix, reproducibility of +/- 0.00002RI / +/- 0.015Brix & accuracy of +/- 0.00004RI / +/- 0.03Brix.  The temperature of the sample can be controlled between 15 to 100 Deg C and with Optional it would be between 10 to 120 Deg C.

MODEL J257: This model is similar to 157 and has a range of 1.26 to 1.72RI / 0 – 100Brix with a resolution of 0.0001RI / 0.01 Brix, reproducibility of +/- 0.0001RI / +/- 0.01Brix & accuracy of +/- 0.0001RI / +/- 0.1Brix. The temperature of the sample can be controlled between 15 to 70 Deg C.

MODEL J157:  The J157 also has a contact presser.  The advantage of this model is that it can also control the temperature from the presser.  This feature becomes very important when samples are volatile in nature.  When the temperature is not controlled from the top the possibility of uneven temperature maintenance and the evaporation of the volatile sample is a real possibility.  This problem has been efficiently addressed by Rudolph from model J157 and above.

J157 controls the temperature of the sample between 15 Deg C to 50 Deg C automatically through Peltier.  The measurement range is 1.33 to 1.53RI / 0 – 100Brix.  It has a resolution of 0.00001RI / 0.01Brix, reproducibility of +/- 0.00002RI / +/- 0.01Brix & accuracy of +/- 0.00002RI / 0.01Brix.
