Kjeldahl – Hanon

K1100/K1100F Automatic Kjeldahl Analyzer

K1100/K1100F Automatic Kjeldahl Analyzer is an automatic device integrating distillation and titration functions designed based on classic Kjeldahl nitrogen determination method. It’s equipped with the latest core control system, powerful automation and high-quality components, can easily achieve automatic waste discharge and cleaning of digestion tubes and titration cups, control system supply and real-time detection of condensation temperature. High-accuracy charging pump and titration system ensure test results accuracy, and multiple fluid level detection gives smooth test process.


  • Automatic distillation, titration, calculation, printing, drain and cleaning function, safety and saving-time
  • Visible titration cup design gives operator real-time control of the whole test process
  • Steam flow is controllable, satisfying different test requirements
  • Regent barrel enjoys fluid absence warning function, ensuring smooth test going
  • High-precision charging pump and titration system enssure test result accuracy
  • Large LCD touch screen gives visual operation and abundant information, enabling user to have a good command of it
  • USB or RS485 interface is optional for PC connection
  • Distilled liquid temperature is detected real time. Emergency stop against temperature anomaly
  • Double distillation model meets different experiments, ti retard the speed of acid-base reaction
  • Digestion tube fasy drain function is used to avoid operator touch distilled hot reagents, protecting operators
  • Printer is built in
