Features

A Large Size Color LCD Screen. A large size Color LCD screen provides all the information that the analyst requires. For instance, real-time titration curves can be a great source for method development. Extremely wide range detection with maximum accuracy. This dependable workhorse has an extremely wide measuring range... From ppm to 100%, its automatic background compensation function allows accurate volumetric measurements of trace moisture levels. Two-Channel expansion capability. The AQV-2100S can also be converted to either a two channel volumetric titrator or a two channel volumetric-coulometric titrator. The volumetric conversion allows the use of two different strength titrants for maximum analytical flexibility. GLP compliant instrument validation promises reliable results. GLP compliant instrument validation functions provide important information such as the life of reagents, the life of electrodes, etc. FDA 21 CFR Part 11 compliant software package is also available.
