Accurate, Reliable, Versatile and Flexible. Denver Instrument’s volumetric titrators are the ultimate automated solution. Simple enough for routine testing but equally suited for advanced analysis and reporting.
Small foot print for minimum counter space, titrant bottle holders to prevent spills, splash-proof instrument casing and only 5 kilogram weight are a few of the innovative features of the Denver Instrument titrators.
4 menu screens to select methods, reagents, electrodes and stirring speeds assist you in the set-up of the titrator for your applications. Predefined electrodes and reagents, each with its own standardization criteria, saves you time in setting up your applications. Select one of the preprogrammed methods for out of the box operation; or customize these methods by modifying, then storing up to 50 methods in non-volatile memory.
Method, electrode and reagent libraries. Select a pre-programmed method from our list or create up to 50 of your own. Predefined electrode and reagent libraries mean you save time and effort setting up your applications. Store up to 30 different electrodes and reagents each with their own standardization and acceptable limit criteria.
The titration assistance program checks the method and if necessary directs you to the appropriate screen for correction. You can enable password protection for routine titrator operation use or disable password protection for supervisor method development.
Numeric keypad, navigation arrows and menu driven messages makes operation of the titrator easy.
Store up to 200 results in non-volatile memory and review your titration data via the instrument display, optional serial printer or laboratory computer. Time and date stamp of all titrations means full traceability of QC samples (if required) and regular samples.
