The ZA-COD100 series COD sensor launched by Suzhou Zhongang Instrument is an environmentally friendly COD/TOC sensor that does not require reagents, is pollution-free, and is more economical and environmentally friendly. Compact in size, easier to install, and capable of continuous online water quality monitoring. Automatically compensates for turbidity interference, equipped with an automatic cleaning device, and maintains excellent stability even under long-term monitoring.

Application areas: rainwater, municipal sewage, industrial wastewater, surface water, drinking water, seawater, natural water bodies, water treatment industry, industrial process control, and other fields.

Measurement principle:
Many organic compounds dissolved in water have an absorption effect on ultraviolet light. Therefore, by measuring the absorption of these organic compounds by 254nm wavelength ultraviolet light, the total amount of organic pollutants in water can be measured. The ZACOD100 series sensor uses two light sources, one 360 and one 360mm ultraviolet reference light, which can automatically compensate for the attenuation and turbidity effects of the light path, thereby achieving more stable and reliable measurement values.
characteristic:
No need for reagents, no pollution, more economical and environmentally friendly
N can measure parameters such as SAC, COD, TOC, etc
Automatically compensating for turbidity interference, with excellent testing performance
N digital sensor, RS-485 output, supports MODBUS
