The ADS550 is a wet section for the Navigator 500 dissolved oxygen analyzer, designed for continuous monitoring of dissolved oxygen in high-purity water applications such as power station boiler feedwater. It houses a maintenance-free, disposable galvanic sensor and integrates a temperature sensor and flow regulating valve within a compact enclosure. The wet section connects to the Navigator 540 transmitter, supporting measurement ranges from 0 to 20,000 ppb with an accuracy of ±5% of reading or ±1 ppb, whichever is greater, and a response time of 1 minute for a 90% step change. It operates with sample temperatures from 5 to 55 °C and maximum sample pressure of 2 bar gauge. The enclosure is rated IP54, with dimensions of 480 mm height, 290 mm width, and 185 mm depth, and weighs 4.5 kg. It requires 24 V DC power supplied by the transmitter and consumes up to 8 W.
Featuring a separate sensor section and transmitter, the Navigator 500 Dissolved Oxygen gives users the option of adding up to four wet-sections to one transmitter, enabling measurement of samples from different measuring points. This not only offers an economic and compact solution, but allows operators to mix and match other parameters within the Navigator 500 range to reduce installation footprint and cost.
