Water Level Sensor section
1. Equipment introduction:
Organic matter dissolved in water has an absorption effect on ultraviolet light. Therefore, by measuring the absorption degree of these organic matter to 254nm wavelength ultraviolet light, the total amount of organic pollutants in water can be measured. The sensor uses two light sources, one 254nm ultraviolet light and one 365nm ultraviolet reference light, which can automatically eliminate the interference of suspended matter and achieve more stable and reliable measurement values.
2. Application direction:
Suitable for scenarios such as drinking water treatment plants, tap water, swimming pools, river water, and corporate wastewater discharge, it can continuously monitor COD concentration in water.
3. Advantages and features of equipment:
Dual light path design: using 254nm ultraviolet light and 365nm reference light to automatically eliminate suspended solids interference;
Low power consumption: Built in power-off information storage, suitable for various usage scenarios;
Corrosion resistance: 316L stainless steel shell enhances equipment durability;
No reagents: The measurement process is pollution-free, economical and environmentally friendly;
Self cleaning: Equipped with a self-cleaning brush to prevent biological attachment and extend maintenance cycles.
