Standard Features of Karl Fisher Kafi+ Smart
  • Advanced Microcontroller based user-friendly, state-of-the-art product design with User interactive software for ease of operation with protection against invalid entries.
  • Quick interchangeable imported burette assemblies with intelligent recognition for its volume size. Burette validation factor for dispensing correction is available for true end point volume.
  • System recognizes proper connectivity of other peripherals like Burette, Stirrer, Electrode, Pen Drive etc. Gives indication incase of improper connectivity.
  • Large memory capacity for method storage with suitable scientific parameters having GLP compliance.
  • Sample Name & Identification Number with Date and Time for authentication. Daily Auto Incremented Run number and Factory entered CUSTOMER NAME & Instrument Sr. No. on report printouts make the system foolproof and GLP compliant.
