Tethys400COD online monitoring instrument

Tethys400 (UV) water quality COD online monitoring instrument parameters:

Measurement principle:

The measurement principle is based on the ultraviolet absorption method, where the waterway in the flow cell is illuminated by ultraviolet light from a xenon lamp. Some components of ultraviolet light are absorbed through a flow cell for detection and analysis. Then, according to the Beer Lambert law, the absorption of this light is measured based on the absorption of unsaturated organic molecules at 254nm.

Main features:

The measurement uses UV absorption method, which has extremely high stability and low maintenance;

A new, responsive, and user-friendly color touchscreen interface;

The newly designed 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 ultraviolet xenon lamp flashes billions of times, and if measured once per minute, its lifespan is greater than 10 years;

→ Built in automatic cleaning system, low-cost 5% sulfuric acid cleaning solution is automatically injected into the sample circulation pool for cleaning, while performing automatic zeroing work;

Single circuit board design makes circuit maintenance extremely convenient;
