Rosemount™ 499ATrDO Trace Dissolved Oxygen Sensor

The Rosemount 499ATrDO Trace Dissolved Oxygen (DO) Sensor is a membrane-covered amperometric sensor for the continuous determination of ppb-level dissolved oxygen in water. This dissolved oxygen sensor is ideal for applications with steam condensate and boiler feedwater. Accuracy: <20 ppb ±1 ppb>20 ppb ±5% of reading Drift: <4% over 60 days Temperature Range: 32 to 122 °F (0 to 50 °C) Measurement Range: 0.1 ppb to 20 ppm Pressure Range: 0 to 65 psig (101 to 549 kPa abs) Materials of Construction: Wetted Materials: Noryl™, Viton™, Teflon (TFE) and silicone
