Working Principles of the KDO300 Probe

To understand how the KDO300 Online Dissolved Oxygen Probe operates, it’s essential to delve into its working principles. The probe employs the amperometric method, a widely used technique for measuring dissolved oxygen. In this method, an electrode is used to measure the current generated by the electrochemical reaction between oxygen and a cathode. The current is proportional to the concentration of dissolved oxygen in the water.

The KDO300 probe consists of a sensing element with a cathode and an anode. When submerged in water, the cathode reacts with the dissolved oxygen, producing a current that is detected by the probe. The probe’s electronics then convert this current into dissolved oxygen readings, providing real-time data on oxygen levels in the water.

Calibration Procedures for Optimal Performance

Calibration is a crucial step to ensure the accuracy of dissolved oxygen measurements. The KDO300 Online Dissolved Oxygen Probe is designed to be easily calibrated, and regular calibration is recommended to maintain precision. Here is a step-by-step guide to calibrating the KDO300 probe:

  1. Prepare Calibration Standards: Obtain at least two calibration standards with known dissolved oxygen concentrations. These standards should bracket the expected range of dissolved oxygen in the measurement environment.
  2. Insert the Probe into Calibration Solution: Immerse the probe into the first calibration standard, ensuring that the sensing element is fully submerged. Allow the probe to stabilize for a few minutes to reach equilibrium.
  3. Calibration Procedure: Follow the manufacturer’s instructions to initiate the calibration procedure. The probe will automatically adjust its readings based on the known concentration of the calibration standard.
  4. Repeat with Second Calibration Standard: Repeat the process with the second calibration standard. This dual-point calibration enhances the accuracy of the probe across a broader range of dissolved oxygen concentrations.
  5. Verify Calibration: After calibration, verify the accuracy of the probe by measuring the dissolved oxygen concentration in a quality control sample. If the readings deviate significantly from the expected values, recalibrate the probe.

Maintenance Tips for Prolonged Performance

Ensuring the longevity and consistent accuracy of the KDO300 probe requires proper maintenance. Here are some maintenance tips to follow:

  1. Regular Cleaning: Clean the probe regularly to prevent biofouling and mineral deposits on the sensing element. Use a soft brush or a mild cleaning solution to gently remove any accumulated substances.
  2. Storage in Calibration Solution: When not in use, store the probe in a calibration solution to keep the sensing element hydrated and maintain its sensitivity.
  3. Inspect and Replace Membranes: Periodically inspect the condition of the membrane. If signs of damage or wear are detected, replace the membrane following the manufacturer’s guidelines.
  4. Battery Check: Ensure that the probe’s battery is in good condition. Replace the battery as recommended by the manufacturer to prevent interruptions in operation.
