Features

A Large Size Color LCD Screen. A large size Color LCD screen provides all the information that the analyst requires. Real-time titration curves can be a great source for method development. Two-Channel expansion capability. An optional coulometric kit is available that will convert the unit to a two-channel coulometric titrator. With this factory-installed kit, you'll be able to quickly and efficiently run both routine samples and those problematic samples that require special reagents (e.g., aldehydes and ketones). Innovative cell design decreases maintenance over the life of the cell. Replaceable membrane combines the superior precision of a ceramic frit with the ease-of-maintenance of a fritless system. Convenient, quick, and safe electrode cable attachment also standard. GLP compliant instrument validation promises reliable results. GLP compliant instrument validation functions are provided to promise reliable results, such as the life of reagents, the life of electrodes, etc Complete control from a PC or laptop with included FDA 21CFR Part 11 compliant software.
