Installation and Maintenance

How to install COD sensor?

1. Although the COD sensor does not have specific orientation requirements when placed in water, it is recommended to place it horizontally for optimal positioning. This helps avoid the impact of debris and foreign objects in the water on the measurements.
2. When suspending the sensor, ensure it does not collide with the container walls due to water flow. If the water flow at the measurement point is fast, make sure to securely fix the sensor.
3. The device should be placed in an area free from bubbles, and when installing the sensor, the depth below the water surface should not exceed 2 meters. Considering water level fluctuations, it is advised to submerge the sensor at least 30 cm below the lowest water level.
4. The device is equipped with an NPT3/4 thread and can be used with our waterproof pipe. The cable should pass through the pipe, and the sensor can be screwed into the waterproof pipe thread.

How to maintain COD sensor?

1. Regularly check the measurement window for any attachments. It can be cleaned with tap water or wiped with a damp soft cloth. For stubborn stains, add a small amount of household detergent to tap water for cleaning. Be careful not to scratch the measurement window during the process.
2. Periodically inspect whether the self-cleaning brush is functioning properly and check for any damage.
3. If the measurement readings are too high, too low, or consistently unstable, check whether the sensor’s measurement window is clean.
4. After 18 months of continuous use, the dynamic sealing component of the self-cleaning device should be returned to the factory for replacement. The actual replacement time may vary depending on the frequency of self-cleaning.
5. The device should be calibrated before each use. For long-term use, calibration is recommended every three months. The calibration frequency should be adjusted based on the monitoring environment.

COD Sensor FAQs

What is COD?

COD (Chemical Oxygen Demand) is an indicator used to measure the amount of reducing substances in water. These substances are primarily organic matter, making COD a key parameter for assessing organic pollution levels in water. A higher COD value indicates a higher level of organic pollution in the water body.

What is a COD sensor?

A COD (Chemical Oxygen Demand) sensor is a device used to measure the level of organic pollution in water. COD represents the amount of oxygen consumed when organic matter in water is oxidized and decomposed, typically expressed in mg/L.

How does a COD sensor work?

Our COD sensor uses the ultraviolet absorption method. Its measurement principle is based on the absorption characteristics of organic matter at ultraviolet wavelengths. By measuring the attenuation of 254 nm wavelength light as it passes through the water, the sensor calculates the COD value at the measurement point.

What is the Ultraviolet Absorption Method?

The Ultraviolet Absorption Method (UV method) is a physical technique for COD detection. This method does not require chemical reagents and is based on the selective absorption of specific wavelengths of ultraviolet and visible light by organic substances in water. By measuring the absorption of monochromatic light by the water sample, the concentration of organic matter is determined, establishing a relationship between absorbance at a specific wavelength and the COD value. The COD value mainly depends on the composition and concentration of organic matter, which strongly absorbs light at 254 nm. By measuring the absorbance of wastewater at 254 nm and using a pre-established correlation between absorbance and COD concentration, the COD value is calculated.

What’s in the packing list?

Loại RS485: Self-cleaning COD sensor, 5m cable, certificate of conformity, warranty card, etc.
Analog Type: Self-cleaning COD sensor, Wang-shaped shell conversion module, 5m cable, certificate of conformity, warranty card, etc.

What should we pay attention to when using COD sensor?

1. The device contains sensitive optical and electronic components; ensure it is not subjected to strong mechanical impacts.
2. Avoid excessive tension or stress on the cables during installation.
3. Prevent the device from prolonged exposure to direct sunlight.
4. Do not touch the measurement window with your hands.
5. Avoid any damage to the measurement window.
6. Ensure no bubbles adhere to the device surface, especially the measurement window, during measurement and calibration.
7. Avoid applying any direct mechanical stress to the device during use.
8. Do not forcibly rotate the self-cleaning brush shaft.

What are the applications of COD sensors?

In addition to traditional industrial wastewater and municipal sewage monitoring, COD sensors can also be applied in various fields such as environmental monitoring, healthcare, and food processing. In environmental monitoring, they can be used to measure the organic matter content in natural water bodies such as lakes, rivers, and oceans, providing data support for environmental protection agencies. In the healthcare sector, they can detect organic substances in intravenous fluids to ensure medical safety. In the food processing industry, they can monitor organic matter in food wastewater and during processing to ensure product quality.
