The CellOx 325 by WTW is a high-performance galvanic dissolved oxygen (DO) sensor, specifically designed for professionals who require accurate and reliable measurements in various aquatic environments and aqueous solutions. Whether for environmental monitoring, wastewater treatment, or laboratory applications, the CellOx 325 is engineered to deliver precise results quickly and efficiently.
One of the standout features of the CellOx 325 is its membrane-covered galvanic sensor, which requires no polarization time. This functionality allows users to perform instant measurements, enhancing workflow efficiency in situations where time is critical. The sensor requires minimal maintenance, reducing downtime and ensuring consistent performance over extended periods of use.
Calibration of the CellOx 325 is simple and intuitive, thanks to its air calibration system. By using air saturated with water vapor in the calibration vessel, users can quickly and accurately calibrate the sensor, ensuring it is always ready for precise measurements. This convenience makes the CellOx 325 an ideal choice for both field and laboratory use.
The sensor is equipped with a 1.5 m fixed cable ending in a waterproof 8-pin plug (IP67), providing robust connectivity even in challenging conditions. The CellOx 325 is designed to withstand harsh environments, with a sensor body resistant to pressure up to 6 bars and capable of operating at depths of up to 20 meters. This durability, combined with its precise measurement capabilities, makes it suitable for a wide range of applications, from shallow streams to deep wells.
The CellOx 325 offers an impressive measurement range, capable of detecting oxygen concentrations from 0 to 50 mg/L, oxygen saturation from 0 to 600%, and partial oxygen pressure from 0 to 1250 mbar. This versatility allows it to be used in various conditions and environments, providing reliable data for critical decision-making processes.
Temperature measurement is also integrated into the sensor, with a range of 0 to 50°C. The sensor's rapid response time, with 99% of the final value displayed in less than 60 seconds, ensures that readings are both fast and accurate. This quick response is crucial for applications where real-time monitoring and adjustments are necessary.
Constructed with high-quality materials, the CellOx 325 is designed for longevity and durability. The working electrode is made of gold, while the counter electrode is made of lead. The body, connection head, and cable gland are made of POM, a robust and durable polymer, while the membrane head is made of FEP with a thickness of 13μm, ensuring precise and stable measurements.
To enhance its usability, the CellOx 325 comes with several essential accessories, including the OxiCal®-SL calibration and storage vessel, which helps maintain the accuracy and longevity of the sensor. Additional accessories, such as a magnetic stirrer and various flow and agitation accessories, are available to tailor the sensor's application to specific needs.
The CellOx 325 by WTW is an exceptional tool for professionals who require precise, reliable, and easy-to-use dissolved oxygen measurement capabilities. Its robust design, combined with a comprehensive range of features, makes it an indispensable instrument for a wide variety of water quality monitoring applications.
