The OPAX-1000 opacity sensor can be used in a variety of different ways. While many of our clients use the OPAX-1000 for product packaging and container opacity testing, another important capability for this sensor is in the monitoring of turbidity in water treatment applications.

Turbidity refers to level of impurities or foreign particulates found in a liquid. Visibly, turbidity produces cloudiness or haziness of varying degrees, with more turbidity producing a thicker, cloudier result. It’s a key indicator of water quality and is therefore highly relevant for water treatment.

A number of common terms and measurements are used for turbidity, including Formazin Turbidity Units (FTU), Formazin Nephelometric Units (FNU) and Nephelometric Turbidity Units (NTU). With the OPAX, it’s simple to use our unique system of two-digit Relative Opacity Units, offering users a quickly recognizable measurement from 0 to 99. In this way, an intuitive numerical output can be used and correspond with a pass/fail detection level or threshold for how pure the sample liquid is, or in other words, eliminating samples when there is too much turbidity present. This will help to not only identify potentially faulty end products, but also signal times at which an entire system or process needs to be adjusted due to a series of samples which register as beneath the minimum threshold.

The OPAX offers real-time quality control and precise, consistent measurement. Working at a distance of up to 300mm, and with three potential choices for light intensity, the sensor shoots its light at the liquid sample, and measures the amount of light which gets reflected back. When more light is reflected, more particulates are present, and turbidity is higher. It’s also important to take into consideration with detection levels and other measurements, how different particulates may reflect different amounts of light, or settle in a quicker amount of time.

Ultimately, the OPAX offers accurate real-time results which provide immediate insight and quick, easy and accurate recognition.

If you’re working with water treatment applications or similar manufacturing or industrial processes, then the OPAX may be just the solution that you’ve been seeking.
