Features
|
| Advanced user-friendly Micro-Processor Controller, state-of-the-art design with alphanumeric splash-proof soft keyboard and interactive software in dialogue mode for ease of operation with protection against invalid entries. |
| Vortex stirrer for vigorous and homogenous stirring, with specially designed glass propeller for chemical inertness. |
| A quickly interchangeable calibrated burette with intelligent recognition for its volume size. Burette factor for dispensing corrections, also available for true end point calculations. |
| Temperature Sensor with 4-line measurement technique ensures correct temperature indication. |
| Composite Differential Electrode Amplifier unit for Potentiometric and Voltametric/Karl Fischer Titrations, with connectivity to various electrodes. |
| During titration, measured variables or the pH value is shown on the display together with dispensed volume and number of EP’s detected. |
| User selectable End Point (EP) evaluation up to 9 EP’s during the run, and calculation by first, last, largest, all or selected EP’s with display of results and printout. |
| Reprocessing of threshold and recalculation of EP without performing the new run. |
| Alphanumeric entry of sample name, titrant name, identification number, date with type of electrode used for authentication. |
| Daily auto incremented run number and factory entered customer name and instrument Serial Number shown on report printouts, making the system Fully GLP Complaint. |
| Dispenser facility for fixed volume dosing or dilution, allowing manual titration with user defined dose and mV indication. |
| Pre-dispense facility with selectable dose and time, for quick titrant without disturbing the titration trend. |
