Galvanic DO Monitoring and Control System

Model 2100 Galvanic DO Analyzer

Model 2100 Galvanic DO Analyzer

The Reliant Model 2100 Dissolved Oxygen (DO) Monitoring and Control System is a rugged, full featured dissolved oxygen analyzer which utilizes a long life, low maintenance galvanic DO sensor.

The Model 2100 Galvanic DO Analyzer provides the user with exactly what they need for continuous DO monitoring and control of important aeration processes - a solid DO reporting system, that seldom requires maintenance or recalibration, always has the correct DO/temperature reading, and communication capabilities to whatever data collection system that might be required. All of this at a lower than reasonable price.

With analyzer features like a backlit display, 72 hour trending on the display, both digital and two analog outputs, and two control relays, the Model 2100 offers the functions of a full-powered, continuous monitoring and control analyzer at close to the price of a portable DO meter. Combined with the rugged reliability and accuracy of a galvanic DO sensor, the Reliant Model 2100 system is the most reasonably priced DO meter on the market.

Model 20 Galvanic DO Sensor

The Model 20 Galvanic DO Sensor utilizes proven galvanic sensing technology – without a question the most accurate and reliable DO sensing technology ever developed. The pure platinum cathode makes the sensor incapable of being poisoned by other gases often found in impure waters, such as hydrogen sulfide. This sensor utilizes the only DO sensing technology that is successful in continuous de-nitrification monitoring and control applications. It is also the only sensor design that can be used continuously in very violent pure liquid oxygen injection systems. Complete systems are supplied with over 5 years of sensor electrolyte and membranes.

When used correctly these Teflon® membranes will last well over a year and can be made to require a minimum of maintenance.

Optical DO Monitoring and Control System

Model 2400 Optical DO Analyzer

The Reliant Model 2400 Optical Dissolved Oxygen (DO) Monitoring and Control System is an economical, full featured optical dissolved oxygen analyzer and a long-life optical sensor that remains in calibration for at least a year.

The Model 2400 Optical DO Analyzer provides the user with exactly what they need for continuous DO monitoring and control of important aeration processes - a solid DO reporting system, that seldom requires maintenance, always has the correct DO/temperature reading, and communication capabilities to whatever data collection system that he might require. All of this at a reasonable price.

With analyzer features like a backlit display, up to 72 hour trending on the display, both digital and analog outputs, and two control relays, the Model 2400 offers the functions of a full-powered, continuous, monitoring and control analyzer at close to the price of a portable DO meter.

Model 24 Optical DO Sensor

The Model 24 Optical DO Sensor utilizes luminescent sensing technology. This sensor is CE approved and is also approved by the ASTM International Method D888-05. This sensor is stable and efficient in very low DO and has a top end range of 20 PPM. The Model 24 is a true Smart sensor that allows for "plug and play" capability. It incorporates the Universal Modbus RS485 protocol which allows up to 4 sensors to be connected to the Reliant Water Model J-240 Communications Module.

The Model 24 can be Jet Cleaned with air by using the unique, heavy duty, Reliant Model SCM Sensor Cleaning Module. This air cleaning system can handle from 1 to 4 Model 24 sensors.

If house water is available without freezing 12 months of the year, the Model SCM-5 is another Jet Cleaning method that can be used for continuous maintenance free service from the Model 24 sensor.

True Smart Sensor Functionality

True Smart Sensor Functionality

For users that have complete SCADA control in their plant, Reliant Water offers the J-240 Communications Control Module. Each J-240 Communications Module can accept up to 4 Model 24 Optical DO Sensors. Each sensor protocol continuously reports both DO and temperature to the plant's central control computer system. The J-240 Module can be located wherever it is most convenient for mounting up to 4 Model 24 sensors.
