Portamess® Oxy 91 : Versatile Dissolved-Oxygen Measurement

The Portamess® Oxy 913 is an advanced dissolved oxygen meter from Knick, designed for users requiring precision and flexibility in their measurements. Combining portability with robust features, this device is ideal for laboratories, environmental monitoring, aquaculture, and various industrial applications. Its cutting-edge technology ensures accurate readings, making it a reliable tool for scientists and technicians.

The Oxy 913 features a sleek and ergonomic design, facilitating handling and transport. The device is housed in a sturdy blue casing, resistant to shocks, chemicals, and water (IP 66 protection). The large, easy-to-read LC display measures 67 x 35 mm and is equipped with anti-reflective natural glass, ensuring clear visibility in various lighting conditions.

User interaction is simplified thanks to a smooth membrane keypad that is durable, easy to clean, and resistant to deposits. The integrated real-time clock with date function enhances data management, allowing users to track measurements over time.

The Portamess® Oxy 913 excels in measuring both the concentration and saturation levels of dissolved oxygen, offering a range of 0.00 to 60.00 mg/l and 0.0 to 600.0 %, respectively. The measurement is precise, with a typical error margin of only 0.5 % of the measured value. This makes the Oxy 913 suitable for high-stakes environments where accuracy is essential.

The device can automatically calibrate in air thanks to its built-in calibration chamber, ensuring minimal user intervention and a streamlined workflow. Furthermore, the calibration timer can be set between 0 and 14 days, with a default setting of 6 days, reinforcing reliability during continuous use.

One of the remarkable features of the Portamess® Oxy 913 is its data logger, capable of storing up to 200 measured values, complete with timestamps and indices. This allows for manual recording, interval-controlled recording (from 5 seconds to 60 minutes), or event-controlled recording based on specified measurement changes. When connected to a PC, the device can continuously log an unlimited amount of data, providing significant advantages for extensive monitoring projects.

To facilitate data transfer, the Oxy 913 includes a bidirectional RS 232 C interface. This allows smooth communication with printers or PCs, significantly reducing the risk of manual transfer errors. The device is compatible with various quality management documentation systems, including ISO 9000 and GLP.

The Oxy 913 is equipped with innovative features designed for user convenience. The Sensoface® sensor diagnostic uses intuitive "smileys" to convey the status of the sensor, allowing users to quickly assess the operational condition of the device. The integrated and removable sensor quiver includes a moisturizing fleece, ensuring optimal sensor performance and ease of replacement.

To enhance the functionality of the Portamess® Oxy 913, several accessories and software options are available. The SW 109 transfer software allows users to record measurement data and memory contents in tabular form, facilitating data management and analysis. It also enables data transfer to other Windows applications, including Excel.

The Portamess® Oxy 913 from Knick represents a combination of portability, advanced measurement technology, and user-friendly design, making it an essential tool for anyone needing reliable dissolved oxygen measurements. Whether in a laboratory or in the field, this device promises precision and efficiency, paving the way for informed decision-making and effective monitoring.
