Auto-Clean: A Revolution in Dissolved Oxygen Sensing

In the realm of environmental monitoring and water treatment, accurate and reliable dissolved oxygen (DO) measurements are paramount. DO levels play a critical role in various applications, from wastewater treatment and aquaculture to industrial processes and environmental research. Traditional DO sensors often suffer from fouling, which can significantly impact their accuracy and longevity. This is where the revolutionary Auto-Clean technology comes into play.

What is Auto-Clean?

Auto-Clean is an innovative feature incorporated into certain DO sensors, designed to automatically remove fouling from the sensor's membrane. Fouling, caused by the accumulation of organic matter, inorganic particles, and microorganisms, can significantly hinder DO readings.

How does Auto-Clean work?

Auto-Clean technology typically employs one of two methods:

  1. Mechanical Cleaning: This involves a physical cleaning action, such as a wiper blade or a pulsating flow of clean water, to dislodge fouling from the sensor membrane.
  2. Electrochemical Cleaning: This method utilizes an electric current to generate electrochemical reactions that break down and remove fouling.

Benefits of Auto-Clean:

  • Improved Accuracy: Auto-Clean ensures that the sensor membrane remains clean, guaranteeing more accurate and reliable DO readings.
  • Reduced Maintenance: By automatically removing fouling, Auto-Clean technology significantly reduces the need for manual cleaning, minimizing downtime and maintenance costs.
  • Extended Sensor Life: Auto-Clean prevents the build-up of fouling, prolonging the lifespan of the sensor and reducing the need for frequent replacements.
