Volumetric Karl Fischer titrator, T930

Volumetric Karl Fischer titrator for water content determination from 0.001% to 100%, with a 10-inch Android touchscreen and FDA 21 CFR Part 11 compliance.

• 10-inch TFT touchscreen running Android: parameters are set and changed with a tap, and data screens are browsed by swiping left or right, for simple, efficient operation
• Modular menu structure gives fast, direct access to every sub-screen for efficient navigation
• The titration curve, parameters and results are displayed in real time during the measurement, so the whole titration can be monitored as it runs
• Results in multiple units, including mg%, ppm, H₂O, ml, mg/ml and mg/g; data retrieval function for quick access to stored records
• V-T and E-T curves can be switched at any time and zoomed in or out manually; 8 GB of storage for methods, data, traceability documents and more
• Sealed reagent management system: the reagent is replaced automatically without opening the titration cell, so moisture from the air cannot enter; the cell re-equilibrates quickly after a reagent change, and operator contact with the toxic reagent is reduced
• Injection ports in several sizes to suit different ways of introducing the sample
• Waste overflow protection prevents the waste bottle from overflowing when full
• Magnetic stirrer as standard, with manual and automatic stirring
• 5 ml burette as standard; 1 ml and 10 ml burettes optional
• Integrated burette system with light-protected tubing to prevent reagent degradation
• Plug-in, fall-proof reagent bottle rack, freely configurable, for 250 ml, 500 ml and 1000 ml bottles
• Dynamic continuous dosing: the dosing rate adjusts automatically from 0.02 µl/s to 0.1 ml/s for precise, flexible reagent addition; a drift resolution of 0.1 µg/min and a dedicated PID algorithm improve accuracy and repeatability and shorten the analysis time
• Built-in methods with one-touch start: titer determination, blank value, water content and other methods are preset; once the sample is added, the instrument detects it and starts the measurement automatically. Analysis parameters can also be customised for specific samples
• Four end-point criteria: relative drift stop, absolute drift stop, end-point delay and maximum time stop, for precise, reliable results even with complex or difficult samples
• Complies with FDA 21 CFR Part 11
• Audit trail: every operation executed on the instrument is recorded in the background
• Four-level user permission management; the permissions at each level can be customised
• Electronic signature and tamper-proof data output for secure, verifiable data integrity
• Password security: passwords can be given an expiry date, after which a change is enforced before the instrument can be used again; password complexity and password ageing period are configurable
• Screen lock after a set time; the instrument keeps working in the background while the screen is locked
• Wi-Fi, USB, RS232, BNC and other interfaces; remote printing on a Wi-Fi printer or printing via RS232, and a mouse and keyboard can be connected to operate the instrument
