The new CAS touch! Charge Analyzing System combines proven methods of particle charge measurement with the known great simplicity of handling and functioning of the previous CAS versions, but enhanced with new features and an immense reduction in weight and size.
Using standard techniques of titration, the CAS touch! determines cationic/anionic and acid/base demands of aqueous charge systems. Modern electronic components enable the high accuracy of measurement. Both, Streaming Potential (mV) and pH can be measured simultaneously, making it possible to easily determine isoelectric and flocculation points of a sample and examine the correlation between pH, titrant demand and streaming potential.
The CAS touch! uses integrated high precision titrators, optionally with 1 or 2 titration systems (CAS-I touch!, CAS-II touch!), while also a version for use with external or hand titration is available to the customer (CAS-E touch!).
Measurement / Result evaluation
The CAS touch! can be operated via Touch Screen, which displays the data including titration curves, optionally in combination with an external keyboard. Moreover, there is no need to adjust to a new software, as the device can also be used with the common easy-to-handle CAS PC software. The efficient testing procedures implemented in extremely user-friendly PC software make it very easy to handle. Different titration procedures are available: fixed increment titration, dynamic titration and back-titration are selectable from given procedures or are freely configurable. Default standard titration procedures and customer-specific processes can be stored in the CAS touch! via the PC software or Touch Screen. Data can be stored internally as well as externally on an USB flash drive, analyzed with PC software and exported to Excel (only two mouse clicks).
Transport / Assembly
The low weight device can easily be transported in a carry-on size case, which is especially important for chemical suppliers for customer visits.
After unpacking the device and connecting it to the mains voltage, the CAS touch! is ready for starting the measurement! There is no complicated assembly and no tubes are needed.
