Sartorius - Model CCL1007 -Vacuum Comparator

• The comparator is protected from environmental effects by a pressure-stable, non-magnetic aluminum chamber.
• The unique three-point holder is capable of handling both cylindrical weights and silicon spheres efficiently.
• The weigh cell is located in the upper section of the vacuum chamber. The weighing pan for the substitution weights is accessed via the upper loading hatch.
• The motors that drive the load alternator and the weight changing device are located outside the vacuum chamber. This reduces interference caused by temperature fluctuations.
• All components inside the vacuum chamber are completely resistant to high vacuum and, therefore, will not outgas under vacuum. This prevents any contamination of the weights.
• The more than 20 vacuum flanges enable additional sensors to be introduced into the vacuum chamber, which has sufficient space to accommodate additional measuring instruments.
• Inclusive Printer and PC

Sartorius has mastered the core disciplines of weighing like no other company. Sartorius sets new standards in mass metrology. In cooperation with the Bureau International des Poids et Mesures and the Institute for Process Measurement and Sensor Technology of the Technical University of Ilmenau, Sartorius has developed a mass comparator — the CCL1007 — that is capable of determining differences in mass to an accuracy of 0.1 μg for weights of 1 kg — even under high-vacuum conditions.
