UDK 149 Automatic Kjeldahl Nitrogen Protein Analyzer (potentiometric)

Reference: VEL-F30200145

The UDK 149 is designed for maximum versatility and reproducible results when determining Kjeldahl nitrogen TKN, proteins, ammoniacal nitrogen, nitric nitrogen (Devarda), TVBN, sulfites, phenols, volatile acids, cyanides, and alcohol content.

UDK 149 can be used in combination with several models of external potentiometric titrators for higher sample throughput and direct output of the final result.

Connection to various external titrators for automated processing and efficient operations
Premium result accuracy and precision
Programmable boric acid, water, sodium hydroxide addition
Selectable steam generation output level 10% – 100%
Auto removal of residues from sample tube
Clear and intuitive operations thanks to the Smart User Interface and digital display
Maximum safety for the operator
Unmatched flexibility with a wide accessory range
