The rising use of nano scaled particles demands new characterization tools. Especially for polishing, grinding and lubricant-suspensions the exact knowledge of the concentration is needed. Based on a new measurement method Aello developed a device, which hasn’t the disadvantages of ultrasonic and coriolis methods.

The Aello 1551 measure the concentration of nano scaled particles. Also the device can determine the type of solids. It was specifically designed for in process installation and completes the Aello product range of plug in sensor probes (e.g. 1500 and 1520). The main applications range from automation for CMP slurry handlings plants to sewage treatment. The used measurement principle owns the advantage of low operating costs and a reasonable purchase price. The device is easy to operate and user friendly to handle. The measurement data can be exported via standard interface to any external programs. A free programmable output permits a direct process control by the sensor.
