Digital Chlorophyll A Sensor

Digital Chlorophyll A Sensor

The Digital Chlorophyll A Sensor is an advanced tool designed to measure the chlorophyll a content in water, providing critical insights into algae levels and the trophic state of a waterbody. This measurement is essential for monitoring water quality, managing aquatic ecosystems, and ensuring the health of drinking water sources.

This sensor is compatible exclusively with the Sper Scientific 870001 Multi-Parameter Water Quality Analyzer, delivering seamless integration and reliable performance.

How It Works

The sensor uses the unique light absorption and emission properties of chlorophyll a, which exhibits distinct spectral peaks. By emitting specific monochromatic light wavelengths into the water, the sensor detects the light emitted at another wavelength. This emitted light is directly proportional to the concentration of chlorophyll a, ensuring precise, real-time data collection.

Key Features

1. Precision and Reliability

• Advanced optical compensation ensures accurate data by counteracting LED drift caused by temperature changes or prolonged use.
• Integrated ambient light rejection and isolated optical frequencies reduce interference for consistently reliable results.

2. Low Maintenance

• Internal diagnostics simplify maintenance by reducing the need for frequent manual checks.
• One- or two-point calibration minimizes time spent on setup while maintaining accuracy.
• Reduced calibration solution requirements make upkeep more cost-effective and convenient.

3. Cost-Effective Customization

• Tailor your setup by installing only the sensors you need, saving on unnecessary hardware and minimizing expenses.
• Easily scalable for different monitoring applications, making it ideal for both small-scale and large-scale projects.

4. User-Friendly Design

• Calibration data is stored within the sensor itself, enabling plug-and-play compatibility with any sonde in your system.
• Intuitive setup and operation make it accessible for both experienced professionals and new users.

5. Versatile Applications

• Perfect for a wide range of water monitoring needs, such as:
  • Chlorophyll a detection at water treatment plant inlets.
