Portamess 911 Oxy: A High-Performance Portable Analyzer for Dissolved Oxygen Measurement
The Knick Portamess 911 Oxy is a portable measurement device designed for the precise analysis of dissolved oxygen in various environments. Utilized in water industries, environmental monitoring, research, and industrial processes, it enables reliable and rapid analyses both in the laboratory and on-site. Its high-visibility LCD screen provides a clear display of measured values, either as a percentage of saturation or oxygen concentration (mg/L). The intuitive interface ensures quick and efficient operation, facilitating use even in demanding conditions.
Designed to withstand field constraints, the Portamess 911 Oxy features a robust construction and IP66 protection, making it resistant to water splashes and chemicals. Its ergonomic housing, comfortable to handle, includes a sensor compartment (quiver) with a moistened felt, ensuring optimal storage of the probe. This configuration allows for immediate measurement readiness without frequent maintenance.
The device is powered by three AA batteries, providing approximately 1000 hours of autonomy. It also features an internal memory capable of storing 200 timestamped values, aiding in measurement traceability. The RS232C interface allows for easy data transfer to a PC for analysis in various formats, including Excel. These features are particularly valued in Good Laboratory Practice (GLP) and ISO 9000 quality management systems.
The precision of the Portamess 911 Oxy is ensured by an amperometric membrane oxygen sensor, providing stable and repeatable measurements. The device covers a wide measurement range from 0.00 to 60.00 mg/L for oxygen concentration and 0.0 to 600.0% for saturation. Automatic barometric and thermal compensation ensures optimal accuracy under all usage conditions.
