Vasthi VEOCOD1005 Series COD Analyzer is a new generation of environmental protection type COD or TOC Analyzer launched by our company that is reagent-free, pollution-free, and more economical and environmentally friendly. Smaller size, more convenient installation, and online continuous water quality monitoring With automatic compensation for turbidity interference and automatic cleaning of the device, even long-term monitoring still has excellent stability.
Many organic substances dissolved in water absorb ultraviolet light. Therefore, the total amount of organic pollutants in water can be measured by measuring the absorption of these organic substances by ultraviolet light at a wavelength of 254 nm. The VEOCOD1005 series analyzer uses two light sources, one 254 nm ultraviolet light and one 850 nm infrared light, which can automatically compensate for the optical path attenuation and turbidity effects, thus achieving more stable and reliable measurement values.
FEATURES :
- Digital sensor, RS-485 output, and support for MODBUS
- No reagents, no pollution, more economical and environmentally friendly
- can measure COD, TOC, and other parameters
- Automatic compensation for turbidity interference results in excellent test performance.

It is an industrial online COD (Chemical Oxygen Demand) analyzer used for continuous monitoring of organic pollution in wastewater.
It measures Chemical Oxygen Demand (COD) to assess the amount of oxidizable organic contaminants affecting water quality.
Ideal for wastewater treatment plants (ETP/STP), industrial effluent monitoring, food & beverage, chemical processing, and environmental compliance.
Yes — it provides isolated analog outputs, RS-485/Modbus communication, and configurable alarm outputs for integration with control systems and SCADA.
Key features include automatic sample handling, high-accuracy sensors, stable performance, and low maintenance for continuous COD monitoring.
