Features

A Large Size Color LCD Screen. A large size Color LCD screen provides all information which operator will need. Real-time titration curve 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. GLP compliant instrument validation promises reliable results. GLP compliant instrument validation functions are provided to promise reliable results, such as information of life of reagents, life of electrodes, etc. Complete control from a PC or laptop is now standard with RS-232 cable included.
