Overview

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.

DDM2911: This is the top-of-the line system with a resolution of 0.00001 g/cm3, repeatability of 0.00001 g/cm3 and an accuracy of 0.00005 g/cm3.
