0.1mg/L COD Water Quality Sensor

KCD310 Online COD Sensor No Reagents No Pollution Small Size More Convenient COD Turbidity And Temperature

1.Principle

Many organic compounds dissolved in water absorb ultraviolet light. Therefore, the content of dissolved organic pollutants in water can be accurately measured by measuring the absorption of these organic compounds to 254 nm wavelength UV light. KCD310 online COD sensor uses two light sources, one ultraviolet light to measure COD content in water, the other reference light to measure turbidity of water, in addition, the optical path attenuation is compensated by a special algorithm, which can eliminate the interference of particulate impurities to a certain extent, so as to achieve a more stable and reliable measurement.

 

2.Features

  • No reagents, no pollution, economic and environmental protection
  • Small size, more convenient installation, online continuous water quality monitoring
  • Cod, turbidity and temperature can be measured
  • Automatically compensates for turbidity interference
  • With a cleaning brush to prevent biological adhesion
  • Small drift, fast response, more accurate measurement
  • Even long-term monitoring is extremely stable
  • Maintenance-free, long service life and low cost
  • Digital sensor, RS-485 interface, Modbus/RTU protocol
  • Low-power electronics, anti interference design

Tips:COD Test Procedures

  1. Prior to completing the COD test, a series of known standards are prepared using KHP (potassium hydrogen phthalate). Most wastewater samples will fall in the high range, so standards of 100, 250, 500 and 1000 mg/L are typically prepared. COD standards can also be purchased.
  2. A COD reactor/heating (150°C) block and a colorimeter are turned on so that both instruments can stabilize.
  3. Pre-prepared low-range (3-50 ppm) or high-range (20-1500 ppm) vials are selected for the COD test based on expected results. Both ranges can be used if expected results are unknown.
  4. One vial is marked as a “blank,” and three or four vials are marked with known standard levels. Two vials are then marked for the wastewater sample to make a duplicate run. Note: If multiple wastewater samples are being run, at least 10% of samples are duplicated.
  5. 2 mL of liquid are added to each vial. In the case of the “blank,” 2 mL of DI water are added. 2 mL of each standard are added to the corresponding vials. If the wastewater sample is tested at full strength, then 2 mL is added to the corresponding vial. If dilution is required, then serial dilutions are performed and 2 mL of the diluted sample are added to the corresponding vial.
  6. Each vial is mixed well and placed into the reactor block for two hours. After two hours, the vials are removed from the block to a cooling rack for about 15 minutes.
  7. The colorimeter is set and calibrated per the specific instructions for that unit (i.e., proper wavelength, blank and standards) and each vial is placed in the unit and the COD concentration read.
  8. If the sample was diluted, the corresponding multiplication is made.
