Dissolved Oxygen Sensor (499ADO)
The Model 499ADO sensor is designed for the continuous determination of dissolved oxygen in water in the range 0 to 20 ppm. The primary application is aeration basins in municipal and industrial wastewater treatment plants. The sensor can also be used to measure dissolved oxygen in aquaculture ponds.
Data Sheet

Dissolved Oxygen Sensor - Trace DO (499ATrDO)
The 499A TrDO is a membrane-covered amperometric sensor. The sensor consists of a gas-permeable Teflon² membrane stretched tightly over a gold cathode. A silver anode and an electrolyte solution complete the internal circuit. During operation, oxygen diffuses from the sample through the membrane to the cathode. A polarizing voltage applied to the cathode converts all the oxygen entering the sensor to hydroxide ions. The reaction produces a current between the cathode and the anode, which the analyzer measures. The current is directly proportional to the rate at which oxygen reaches the cathode, which is ultimately proportional to the concentration of oxygen in the sample.

Dissolved Oxygen Measuring System (DO)
The Model DO-03/04 is a complete system for the determination of dissolved oxygen in wastewater aeration basins. It consists of a sensor, an analyzer, a handrail mounting assembly, a sensor washer head, and an air compressor. A timer in the analyzer allows the user to customize the air blast cleaning cycle.

Dissolved Oxygen Sensor (430)
The Rosemount Analytical Model 430 Dissolved Oxygen Sensor, used with the Model 1181 Dissolved Oxygen Analyzer, measure oxygen levels in a variety of applications. The most widely used application is the secondary phase of the waste treatment process where a critical dissolved oxygen level must be maintained for the digestive process to occur. Other applications include water quality monitoring in natural bodies of water such as rivers and streams, or any location where adequate oxygen content is important to sustain aquatic life.

Dissolved Oxygen Sensor - ppb (Bx438)
The Model Bx438 sensor is designed to monitor trace levels of dissolved oxygen in beer and other carbonated beverages. The Bx438 sensor utilizes a robust membrane, which increases the life of the membrane. The sensor is designed to withstand significantly more clean in place (CIP) cycles than other dissolved oxygen sensors.

Dissolved Oxygen Sensor - Steam Sterilizable/Autoclavable (Gx448)
Emerson Process Management, Rosemount Analytical, sterilizable dissolved oxygen sensors are designed to exceed industry standards. Other dissolved oxygen sensors used for biopharmaceutical applications have less reliable performance and high maintenance requirements, resulting in high costs and/or short sensor life. The Rosemount Analytical Model Hx438 and Gx448 sensors are a result of many years of experience in sensor manufacturing and have resolved these problems.
