Used for assessing water content in petroleum and petrochemical products including oils, gasolines, solvents, and fluids as well as other products in the Pharmaceutical, Cosmetic, Automotive, Food/ Beverage and Agriculture industries. Volumetric Karl Fischer Titrator • Intuitive keypad and function guide display • Automatic and periodic elimination of bubbles which can form in the liquid circuit • Automatic drift monitoring and compensation • Flexible-can be used with different reagent brands • 2 x 5mL syringes- one for the KF reagent and the other for automatic dosing of standard for the titre ( second syringe can also be used for different factor reagent or special reagents for ketones, amines, etc.) Syringe volume dispensed in 40, 000 steps • 2 x built in pumps- one for dispensing the solvent and other for emptying the vessel • 2 x electrovalves- fitted to top of each syringe, control flow direction of solvent and reagents • Automatic rest cycle ( stand-by mode) if not used for 15 minutes • Programmable- several easy to use programs for titration and standardization • Results expressed in ppm, mg/ l, % , etc. • Connects to external PC keyboard for easy text and sample information data entry • Connects to different types of printers, PC’ s and balances • Data Logger- automatic data storage of last 55 analysis results The AKF6000 Compact Volumetric Karl Fischer Titrator is a versatile instrument capable of conforming to a multitude of Standard Test Methods. This fully programmable titrator offers several easy to use programs for titration and standardization. 4 standardization methods can be selected by the user. The AKF6000 then determines the reagent factor and automatically stores it in the titration programs. The AKF6000 is equipped with 2 Peristaltic Pumps capable of automatically dispensing a required volume of solvent into the titration vessel as well as emptying the contents of the vessel directly into a waste container. The built in Drift Monitoring System automatically determines the vessel drift after a titration has concluded. This drift value is then deducted from a later titration. The AKF6000 will prompt the user if the measured drift value is greater than the programmed limit value. Specifications Conforms to the specifications of: ASTM D789, D803, D890, D1123, D1152, D1193, D1348, D1364, D1568, D1631, D2072, D2575, D3401, D4017, D4377, D4672, D5460, D5530, E180, E203 Non-volatile memory: Up to 10 titration programs, Clock/ calendar, Header texts: 2 lines x 40 characters Name of up to 4 operators Program comments: 8 lines x 40 characters Up to 55 results stored in Data Logger Languages: English Spanish, French, Latin Display: Graphic backlit LCD, 128 x 64 dots Keypad: Membrane, 7 keys, guaranteed up to 6 million strokes per key Material: PET with protective treatment Measuring ranges: From 0.1 mg up to 100% water Syringe volume: Standard syringe 5mL Resolution: 1/ 40000 of syringe volume Dispensing accuracy: ( as relative error) d0.2% for volumes higher than 10% of the syringe Dispensing reproducibility: ± 0.1% for volumes higher than 10% of the syringe Liquid contact materials: Syringe: borosilicate glass and PTFE Electovalve: PTFE and KEL-F Tubes: PTFE Inputs and outputs: Polarized electrode, BNC connector For external keyboard, miniDIN connector RS232C bidirectional for PC or printer, telephone connector RS232C for balance, telephone connector Stirrer control: On/ Off and speed, RCA connector Electrical Requirements: 90-264VAC, 47-63 Hz, 24V DC Electrical safety: Meets EC, EN61010 EMC: Meets EC, EN 50081-2 and EN 50082-2 Permitted temperatures: Operating: 15-40° C Storage: -10-50° C
