Potentiometric Auto Titrator

Titration or potentiometer is a instrument used for quantitative chemical analysis.Titra smart is provided with a two point auto calibration and standardisation (zero offset). The potentiometric Autotitrator Titra smart is capable of displaying pH and mV of the sample with temperature compensation. The liquid path comprises Teflon material and glass tight burette which creates chemically inert system for any sensitive analysis.

The 21 CFR part 11 compliance has audit trail which logs all the activities with search facility, report generation and printing. There is also a Electronic Signature functionality in Titra smart. As a standard the potentiometric smart Titrator has a manual archive and data backup facility.

Potentiometric Auto Titrator
Standard Features of Potentiometric Auto Titrator Titra Smart
  • User interactive for ease of operation with protection against invalid entries.
  • Vortex stirrer for vigorous and homogenous stirring with specially designed glass propeller for total chemical inertness.
  • Quick interchangeable imported burette assemblies with intelligent recognition for its volume size. Burette factor for dispensing corrections is available for true end point calculations.
  • System recognises proper connectivity of other peripherals like Burette, Stirrer, Electrode etc. gives indication in case of improper connectivity.
  • Composite Differential Electrode Amplifier unit for Potentiometric and Voltametric / KF Titrations, having connectivity to various Electrodes. Temperature Sensor with 4-line measurement technique ensures correct temperature indication.
  • Large memory capacity for method storage with suitable scientific parameters having GLP compliance.
  • Standardised modes of titration, namely incremental, equilibrium of titration.
  • By selecting titration method, instrument prints the type of appropriate electrode.
  • During titration, the measured variable i.e. electrode potential (mV) or the pH value is shown on the display together with dispensed volume and number of End Points (EP) detected.
  • User selectable End Point (EP) evaluation up to 9 EP during the run, and calculation by first, last, largest, all or selected EP with display of results and printout.
  • Audit Trail for all activities with search facility, report generation and printing.
  • 200 User IDs with alphanumeric entries of user name, password and role based privileges selection.
  • Multi-level roles with password protection and complexity.
  • User authentication is per formed for each and every operation done.
  • Customizable PDF report file can be created through print.
  • USB Printing eliminates the need of serial port to connect with instrument. The user can take printout on any local or network printer as well.
  • Electronic signature functionality.
  • Manual Archive and Data Backup facility available.
