The term "Polymetron" is synonymous with reliable and accurate water analysis within the environmental and water treatment industries. This name, once associated with the renowned Swiss company Zellweger Analytics, Inc., now represents a legacy of innovation and precision in water quality monitoring.
Zellweger Analytics, Inc. was a pioneer in developing and manufacturing advanced water analyzers, earning a reputation for building robust, field-proven instruments. Their product line, encompassing the Polymetron brand, spanned a wide spectrum of applications, from basic conductivity and pH measurement to sophisticated multi-parameter analyzers for demanding industrial and environmental monitoring.
Here's a glimpse into the diverse range of Polymetron water analyzers:
1. Conductivity Meters: Measuring the ability of water to conduct electricity, these instruments are essential for monitoring water purity, salinity, and overall dissolved solids content. Polymetron conductivity meters were known for their high accuracy, stability, and user-friendliness.
2. pH Meters: Precisely measuring the acidity or alkalinity of water, Polymetron pH meters were widely used in water treatment plants, industrial processes, and environmental monitoring. Their robust design and reliable performance ensured accurate results even in challenging conditions.
3. Dissolved Oxygen Meters: Measuring the amount of dissolved oxygen in water is crucial for evaluating water quality, particularly in aquatic ecosystems. Polymetron dissolved oxygen meters were renowned for their accurate measurement of oxygen levels, even in low concentrations.
4. Turbidity Meters: Measuring the cloudiness or haziness of water, these instruments are essential for monitoring water quality and ensuring proper filtration. Polymetron turbidity meters provided reliable and consistent readings, aiding in efficient water treatment and environmental monitoring.
5. Multi-Parameter Analyzers: Combining multiple sensors for comprehensive water quality assessment, Polymetron multi-parameter analyzers were designed for demanding applications. These instruments could simultaneously measure various parameters like pH, conductivity, dissolved oxygen, turbidity, and more, offering a complete picture of water quality.
The legacy of Polymetron lives on: Although Zellweger Analytics, Inc. has since been acquired by Endress+Hauser, the name Polymetron remains a symbol of excellence in water analysis. The company's dedication to innovation and precision continues to shape the industry, ensuring that the Polymetron legacy of accurate and reliable water quality monitoring remains strong.
Today, Endress+Hauser continues to build upon the foundation laid by Zellweger Analytics, offering a comprehensive range of water analyzers and solutions that meet the evolving needs of the environmental and water treatment industries. The spirit of Polymetron, with its commitment to precision and reliability, remains at the core of their offerings.
