Features

  1. The cover is made of specific powder-coated steel plate, resists chemical reagents and mechanical erosion
  2. Simple structure, button control, easy to operate
  3. Optimized internal configuration, convenient to install and maintain
  4. Touch buttons to add distilled water, alkali, and vapor-controlled, no need to contact with the reagent
  5. Short distillation duration, work efficiency enhanced

Differences between different models of Kjeldahl Analyzers

The DW-ATN-100 is Manual, While The DW-ATN-300 is Automatic.

Neither the DW-ATN-100 nor the DW-ATN-300 Includes a Titration Device; The User Can Perform The Titration Process Manually.

Both the DW-ATN-100 And DW-ATN-300 Require An Optional Pretreatment Digestion Furnace.

FAQ

Check cooling water circulation switch and unclog condenser pipeline to maintain continuous cooling water flow, otherwise ammonia gas will escape and lead to low test results.

Insufficient sodium hydroxide or excessive acidity of digested liquid. Appropriately increase the injection volume of lye to fully neutralize acid and release ammonia.

Check whether the indicator fails and eliminate air bubbles in titration pipeline. Replace mixed indicator regularly and observe the end point in standard operation.

Rinse distillation and titration pipelines with pure water after each test. Regularly clear crystal blockages in waste pipelines to avoid pipeline corrosion caused by residual strong acid and alkali.

Nitrogen impurities exist in distilled water or reagents, and digestion tubes/distillation cups are unclean. Replace nitrogen-free pure water and fresh reagents, thoroughly clean all containers and retest blank.
