COD/ammonia nitrogen two in one online monitoring instrument

The Tethys400 COD/ammonia nitrogen two in one online monitoring device is mainly used in fields such as river water and wastewater treatment.

The Tethys400 COD/ammonia nitrogen two in one online monitoring device is mainly used in fields such as river water and wastewater treatment.

The circulation pool can withstand extremely high concentrations of suspended particles, such as activated sludge, without the need for filtration, without clogging, and without affecting measurement results
Two parameters are measured using the same waterway and displayed simultaneously on the color touch screen in separate screens

Tethys400 COD/Ammonia Nitrogen Two in One Online Monitoring Instrument Parameters:

Main features:

The measurement principle of COD adopts ultraviolet absorption method, which has extremely high stability and low maintenance

The circulation pool can withstand extremely high concentrations of suspended particles, such as activated sludge, without the need for filtration, without clogging, and without affecting measurement results;

The measurement method of ammonia nitrogen is based on the ultraviolet absorption spectrum of ammonia in equilibrium with the liquid phase. This method has strong selectivity and does not cause any interference when measuring river water or wastewater;

When measuring ammonia nitrogen in the gas phase, there is no effect on the turbidity and chromaticity of the water being measured;

Two parameters are measured using the same waterway and displayed simultaneously on the color touch screen in separate screens;

→ Compact structure and high integration level
