UV254 COD/TOC Sensor ZWIN-COD1006

PRODUCT INTRODUCTION

Many organic substances dissolved in water have an absorption effect on external light, Therefore, by measuring the degree of absorption of these organic substances to 254nm wavelength ultraviolet light, the total amount of organic pollutants in the water can be measured. The UV254COD/TOC online analyzer uses two light sources, one 254nm ultraviolet light and one 365nm reference light, which can automatically compensate for the attenuation of the light path and the influence of turbidity, thereby achieving more stable and reliable measurement values.

PERFORMANCE PARAMETERS

1.Measurement principle: dual beam absorbance method:254nm(COD detection)；365nm reference light (eliminating the interference of suspended matter)
2. Measurement parameters: Simultaneous measurement of CODcr, TOC, turbidity and temperature. BOD,CODMn and other parameters can be converted.
3.Measurement optical path: 6mm or 1mm.
4. Range (6mm): CODcr: 0-500mg/L; TOC: 0-250 mg/L (both using potassium hydrogen phthalate solution,KHP); turbidity: 0-500NTU.
Range (1mm): CODcr: 0-3000mg/L; TOC: 0-1500 mg/L4 (both using potassium hydrogen phthalate solution,KHP); turbidity: 0-3000NTU.
5.Accuracy: CODcr and TOC are both 5%; turbidity accuracy is 3%.
6. Resolution: CODcr is 0.01mg/L; TOC is 0.1mg/L ; Turbidity resolution is 0.1NTU.
7. Response time: 1s.
8. Light window cleaning method: automatic cleaning with standard cleaning brush.
9. Sensor compensation: supports automatic compensation of temperature and turbidity.
10.Temperature application range: 0-45°C.
11. Protection level: lP68. Maximum pressure: 1 bar.
12. Calibration method: 1 or 2 points.
13.Communication method: RS485 (Modbus RTU).
14. Power supply voltage: 12V DC+5%.
15. Power consumption: ≤0.6W (when not cleaning).
16.Cable length:10m(customizable).
17. Housing material: POM and stainless steel 316L.
18.Installation method: immersion installation.
19.Probe size (DXL):ф50mmx214mm.
