Automatic Detection 

Acid addition, alkali addition, distillation, titration, result calculation and printout are fully automatic, and automated sample testing

Sample Explosion Proof

Unique sample dilution and alkali addition methods can be set arbitrarily according to different user samples to prevent the occurrence of sample bumping and improve the measurement accuracy

Alkali Pump Anti-crystallization

The self-developed alkali pump anti-crystallization technology solves the problem of alkali pump crystallization and improves the reliability of the instrument

Steam Adjustable

The steam flow can be automatically adjusted to better achieve the distillation effect and ensure the accuracy of the experiment

Dual Mode Titration

Using dual-mode titration, the combination of thickness and fine titration will ensure the high accuracy of the results; the titration method conforms to AOAC, EPA, Din, ISO and other certification methods, and the titration adopts the officially recognized color titration method

End Point Judgment

End-point color user fine-tuning technology and end-point color learning technology ensure the adaptability of accurate testing and show more humane care

Titration Vessel Empty

After the sample is distilled, the instrument automatically completes the emptying of the residual waste liquid in the sample tube, and the titration cup is automatically drained and cleaned.

Safe Protection

Multiple intelligent protections such as digestive tube presence detection, safety door, condensate detection, steam generator overheating, overpressure protection, liquid level detection, etc. ensure the safety of instruments and operators
